These instructions are only for the Firmware Version: 3.6. This document was last edited on February 28, 2023

EtherNet/IP Connection Parameters Starting from version 3.6 two different ethernet modules (HMS and Hilscher) are used. An appropriate EDS file may be used to import the module in the PLC. In case a manual setup is performed then the following information may be used to set the module as a generic EtherNet/IP module in the PLC.

Assembly Instance Size Bit

Input 100 16 16-bit

Output 150 8 16-bit

Configuration 1 0 8-bit

PROFINET Connection Parameters Ethernet module configuration value based on the PROFINET GSDML file.

Input Module Slot 05 to 08 32 Bytes

Output Module Slot 01 to 04 16 Bytes

NOTE: For PROFINET systems the 16-bit data from the controller are split into two bytes and byte swapped. The register map shown below is how the 16-bit data is stored in the controller and sent out through the ethernet network. The PROFINET PLC might read the data in little endian format with the least significant byte first. So the 16-bit data from the controller would need to be byte swapped to read the correct 16-bit value.

EtherCAT Connection Parameters Ethernet module configuration value based on the supplied ECS File. The EtherCAT master will set all the information automatically based on the FMMU setting in the ECS file. The information provided is only for reference.

Input 0x1100 32 8-bit

Output 0x1D00 16 8-bit

Open Modbus/TCP Ethernet module configuration for Open Modbus/TCP. Reading or writing beyond the size provided here would provide random values. Address Size Bit Function Codes Supported

Input 30001 16 16-bit 04

Output 40001 8 16-bit 03 or 06 or 16

14-15 0-3 Sensing mode 0: edge sensing mode

1: contrast position sensing mode

Note: If both the left sensor and the right sensor bits are set then the configuration corresponds to center sensor mode. A single sensor may be used to measure the position of the two edges of the web, if the width of the web is smaller than the sensing window of the sensor.

Sensor 1/Sensor 2 Left Edge If sensing mode is edge, then this register will provide the left edge of the web.

Note: If the sensor orientation is set to the right sensor then this value would be zero. Note: If the sensor orientation is set to the right sensor or if the sensor mode is contrast, then this value would be meaningless.

Sensor 1/Sensor 2 Right Edge or Contrast If sensing mode is edge, then this register will provide the right edge of the web. While in contrast mode this register will provide the contrast position. In edge mode this register value is meaningful with either the right sensor or with center sensor.

Note: While in contrast mode if the sensor sees no contrast then this value would equal to the number of pixels in the sensor.

In either sensor orientation (left or right) the measured position increases as the web moves from left to right.

Note: If no sensor bit is set or if no web bit is set then the value in the sensor position output register is meaningless.

Sensor Orientation Completely open Fully covered

Left sensor orientation Number of pixels 0

Right sensor orientation 0 Number of pixels

Note: The output when the web completely covers the sensor or when the web is completely outside the sensor window would be different based on the sensor orientation.

Note: If a single web (with two edges) is seen by the sensor, then the width of the web can be obtained by taking the difference between right and left edge positions.

Note: If a single web (with two edges) is seen by the sensor, then the centerline of the web can be obtained by taking the average of left and right edge position.

Sensor 1/Sensor 2 Coverage The sum of individual widths of webs is provided as the coverage value. Individual width is defined as the region between two rising edges on an image captured. When one web with two edges is present, the coverage value will equal the web width. When multiple webs are present, then the coverage value would correspond to the sum of individual widths.

Note: When only one web (with both edges within the sensor field of view) is presented to the sensor the coverage value will be the same as the web width, The coverage value is computed based on edges seen by the controller. Hence, based on the controller settings if multiple contrasting features on the web are seen, then coverage value will not be the same as the web width.

Note: The complement of coverage is the gaps. So if a web is completely covering a sensor's viewing area, then a gap in the web can be detected by seeing a drop in coverage value. Sum of all gaps = Number of Pixels - Coverage.

Note: This measurement is an instantaneous raw measurement for each sensor. Enabling and disabling the filter in the controller will have no effect on the measurement output.

Quality Factor Registers The quality of the sensor measurement from the two sensors are provided in this register. Higher numbers correspond to good quality measurement while a low number indicates lower quality. The value of the quality factor ranges from 0 to 256. The eight most significant bits of register 6 correspond to the 8-bits quality factor from sensor 1 while the eight least significant bits correspond to the quality factor of sensor 2.

Actuator Position The position of the actuator is provided in LSB of this register. The 8-bit register has the actuator position percentage from 0 to 100. If the motor polarity is normal then the actuator position value will range from 0 to 100. If the motor polarity is reversed then the actuator position will range from 128 to 228.

Motor Polarity Motor polarity set on the SCU5 controller is shown in this register. Normal polarity is 1 and reversed polarity is 0. When in normal polarity the actuator will extend while jogging right and retract while jogging left. When in reverse polarity the actuator will extend while jogging left and retract while jogging right.

Sensor 1 /Sensor 2 Web Width When the SCU5 controller is set to provide the width, these registers provide the width output from the controller. Registers 14 and 15 are combined to provide a 32-bit value. The most significant 16-bits are provided in register 14 and the least significant 16-bits are provided in register 15.

Note: The web width measurement provided in this register is in the number of pixels. In order to convert that measurement to engineering units the conversion is as follows: 1 pixel = 0.0635 mm or 1 pixel = 0.0025 in.

Note: The web width measurement output includes the compensation factor that is calculated during the teaching process. For example, when two sensors are used to measure the two edge positions, the width measurement output includes the compensation based on the distance between the two sensors.

Note: The register will have a valid output only after the controller is taught for the nominal web width on the SCU5.

Note: If the filter is enabled the output provided would be the filtered output.

When the SCU5 controller is not set to provide width, then the registers provide the mean widths of the webs seen by each sensor. Register 14 will provide the mean width of the webs seen by sensor 1 and register 15 will provide the mean width of the webs seen by sensor 2.

Note: The mean width is computed by adding all the widths of the webs seen by each sensor and dividing it by thread count. This measurement is an instantaneous raw measurement for each sensor. Enabling and disabling the filter in the controller will have no effect on the measurement output.

Sensor Command Register The bits in the command register are organized as follow:

Bit # Value Label Description

0-1 0, 2 or 3 Sensor orientation 0: set sensor orientation to be right sensor 2: set sensor orientation to be left sensor 3: set sensor orientation to be center sensor

Bit 7 must be set to 1 in order for this functionality to work remotely.

2 0/1 Sensing mode 0: set the sensing mode to be edge mode 1: set the sensing mode to be contrast mode

3-5 0-7 Analog mode 0: Analog output is disabled.

1: Analog output is enabled and zero scale voltage/current is output. Note: This mode can be used during calibration while connecting the controller to a third-party controller that requires calibration. During the calibration, this mode can be selected to calibrate for zero scale output.

2: Analog output is enabled and full scale voltage/current is output. Note: This mode can be used during calibration while connecting the controller to a third-party controller that requires calibration. During the calibration, this mode can be selected to calibrate for full scale output.

3: Analog output is enabled and the analog output corresponds to the left edge position. Note: When the sensor is uncovered by the web the zero scale analog value would be output. As the web moves left to cover the web, the analog value would increase and reach the full scale value when the web completely covers the sensor.

4: Analog output is enabled and the right edge position is output. Note: When the sensor is uncovered by the web the zero scale analog value would be output. As the web moves right to cover the web, the analog value

These instructions are only applicable to the Firmware Version: 3.6 Document Date: February 28, 2023 All Right Reserved. Copyright © 2020 Roll-2-Roll Technologies LLC. Content subject to change without notice. Page 9 of 14

would increase and reach the full scale value when the web completely covers the sensor.

5: Analog output is enabled and the center line position is output. The centerline position is the average of the left and the right edge position of the web. Note: If only one edge is seen the output would be the average of the edge position within the window and the extreme position corresponding to the unseen edge.

6: Analog output is enabled and the width of the web is output. The width is computed by taking the difference between the rightmost edge position and the leftmost edge position. The analog output is proportionally scaled based on the sensor range. The ratio of the web width to the sensor range is output through the analog. If two sensors are used then the width would only correspond to the portion of the web that is seen by each sensor.

7: Analog output is enabled and the web coverage is output. The coverage is the percentage of the sensor covered by web(s). This is used when webs can have gaps or voids in them. Unlike width output, which takes the leftmost edge and the rightmost edge, the coverage will not include the gaps/void between the leftmost edge and the rightmost edge.

Note: There is only one analog output while two sensors can be connected to the controller. Please be aware that enabling the analog output for the sensors would result in unpredictable results. Always disable one sensor while selecting the output of the other sensor.

Note: If the sensor orientation is left sensor or right sensor then the analog mode selection value of 3 - 7 will have no effect. The analog output would always correspond to the respective orientation.

Note: The analog mode 2 has the highest priority followed by mode 1. If any one of the sensors have these bits enabled then the analog output will always provide the high or low output based on the priority. Always disable one sensor while selecting the output for the other sensor.

6 0/1 Find sensor 0: Disable find sensor operation 1: Enable find sensor operation by resetting the orientation and allowing the sensor to detect the web orientation. Note: This bit is momentary when set to one. Every time the find sensor operation needs to be enabled the bit needs to be cleared to zero before setting it to one.

7 0/1 Disable Auto 0: Enable the auto switch functionality for sensor orientation. Find sensor will Switch work only when this is cleared to zero. 1: Disable auto switch functionality so that the sensor orientation can be forced remotely. This bit must be set to one before bit 0 and bit 1 can be changed.

8-13* 0-63 Minimum contrast Minimum contrast: Minimum contrast required to accept an edge in contrast mode. Default value is 32.

14* 0/1 Sub Pixel 0: Disable sub pixel resolution Resolution 1: Enable 4x sub pixel resolution

15* 0/1 Static Threshold 1: Static thresholding algorithm 0: Dynamic thresholding algorithm

* A previous version of the firmware used all eight bits for contrast. The actual contrast value can only change from 0 - 100 on the display. The latest version would allow remote input between 0 and 63.

Sensor Brightness Command Register

Remote Light Control (RLC) Bit 15 on register 2 has to be set to 1 to allow remote control of LED brightness to take effect. If this bit is cleared to zero, changing any of the other bits in register 2 and 3 would have any effect on the LED brightness.

Remote Brightness Limit (RBL) Bit 14 on register 2 allows the user to set brightness limits remotely. In normal operation the brightness of the individual sensors are allowed to vary from 4% to 100%. However, power users can change that limit through ethernet by setting this bit and writing values to the two remaining 7-bit registers.

Maximum and Minimum Brightness Limit The maximum value for the brightness of the LEDs can be written to bits 13 - 7 while the minimum value can be written to bits 6 to 0.

Note: These maximum and minimum limits are for both the sensors even though the brightness for individual sensors may be different. The upper limit cannot be smaller than the lower limit value.

Note: If bit 15 is not set (or cleared to zero), this will have no effect.

Note: The limit value set through ethernet can change from 0 to 125 while the limit value set from the controller can change from 0 to 100.

Note: The limit will take effect even when the brightness is changed manually as well as if allowed to change automatically.

WARNING: When the ethernet connection is removed or disabled, the limits will be set permanently on to the controller settings. So if the controller would ever be used for standalone operation make sure to rewrite the lower limit to 5 and the upper limit to 125.

WARNING: If the Sub Pixel Resolution is enabled on the SCU5 controller while the bit 14 is cleared on the PLC, a power cycle will cause the controller to revert back to normal resolution. Please set or clear the bit through the Ethernet interface to ensure proper operation.

WARNING: If the Static Threshold is enabled on the SCU5 controller while the bit 15 is cleared on the PLC, a power cycle will cause the controller to revert back to Dynamic Threshold. Please set or clear the bit through the Ethernet interface to ensure proper operation.

Sensor 1/Sensor 2 Automatic Brightness Control (S1A and S2A) The automatic brightness control can be enabled or disabled by setting and clearing the appropriate bits in register 3. Bit 15 and Bit 7 in register 3 control this functionality. When the bits are set, the brightness is automatically adjusted by the controller and when cleared the brightness is frozen.

Note: If bit 15 in register 2 is not set (or cleared to zero), this will have no effect.

Note: When the automatic brightness control bit is cleared, the actual brightness value would be the last value before the operation. If needed, the user can then remotely adjust the brightness value by writing to the corresponding brightness register for the corresponding sensor after enabling the corresponding brightness override register.

Sensor 1/Sensor 2 Brightness Override (S1BO and S2BO) Bit 14 and bit 6 of register 3 allows a remote brightness override functionality. When these bits are set, the user can remotely set the brightness by writing a 6-bit value to the corresponding sensor.

These instructions are only applicable to the Firmware Version: 3.6 Document Date: February 28, 2023 All Right Reserved. Copyright © 2020 Roll-2-Roll Technologies LLC. Content subject to change without notice. Page 11 of 14

Sensor 1/Sensor 2 Brightness Override Value The brightness of Sensor 1 and Sensor 2 can be changed remotely by writing a value between 0 to 64 in these two 6-bit registers. The corresponding brightness override bit has to be set before these values can be accepted by the controller. This advanced feature is typically used by power users with a really good understanding of the brightness control algorithm.

Note: If automatic brightness control is enabled and a remote brightness value is written, then the automatic brightness control algorithm will use that value as the initial value for its algorithm. The final brightness may or may not settle to the override value. This functionality may be useful for some advanced applications.

8 0/1 Remote control 0: if cleared to zero, the local operator interface have control over the web guide 1: if set to one, the remote ethernet controller has control over the web guide. The interface icons to control the web guide on the local operator interface will be disabled. Information for monitoring purposes will be displayed on the screen.

9 0/1 Manual/Auto 0: if cleared to zero, the web guide will be placed in the manual mode mode 1: if set to one, the web guide will be placed in the automatic mode

10 0/1 Jog Left or This bit performs two functions based on bit 9. decrease If bit 9 is cleared: guidepoint ● 0: Stop Jog Left operation ● 1: Start Jog Left operation Note that this register is a write only register and will not change state if the web guide reaches the extreme position. If bit 9 is set: ● 0: will clear the register and has no effect ● 1: will decrease the guide point by 0.254 mm or 1/100th of an inch from the current value. Note that this value on this register is momentary. Before decreasing the guidepoint the bit needs to be cleared before setting it to one. Note that the guide point cannot be at the extremes of the sensing window and will automatically truncate if the extreme limit is reached. The extreme limit depends on the sensor resolution and sensor width.

11 0/1 Jog Right or This bit performs two functions based on bit 9. increase If bit 9 is cleared: guidepoint ● 0: Stop Jog Right operation ● 1: Start Jog Right operation Note that this register is a write only register and will not change state if the web guide reaches the extreme position. If bit 9 is set: ● 0: will clear the register and has no effect ● 1: will increase the guide point by 0.254 mm or 1/100th of an inch from the current value. Note that this value on this register is momentary. Before increasing the guidepoint the bit needs to be cleared before setting it to one. Note that the guide point cannot be at the extremes of the sensing window and will automatically truncate if the extreme limit is reached. The extreme limit depends on the sensor resolution and sensor width.

12 0/1 Servo Center This bit performs two functions based on bit 9. operation or set If bit 9 is cleared: guide point ● 0: No effect ● 1: Start Servo Center operation Note that this register is a write only register and will not change state if the web guide reaches the center position. Note that this value on this register is momentary. Before a servo center operation the bit needs to be cleared to zero before setting it to one. If bit 9 is set: ● 0: will clear the register and has no effect ● 1: will set the guide point to be at 50% of the sensing window. Note that this value on this register is momentary. Before decreasing the guidepoint the bit needs to be cleared before setting it to one. The extreme limit is set such that at least ±3.175 mm is available on either side of the adjusted guide point.

13 0/1 Enable arbitrary This bit allows arbitrary gross adjustment of the guide point offset through gross guide point the industrial ethernet interface. adjustment 0: if cleared to zero, gross guide point adjustment is disabled 1: if set to one, the remote ethernet controller can make arbitrary gross adjustment to the guide point by writing a 16-bit signed integer to the guide point register.

14 0/1 Reset Guidepoint 1: Initiate reset guidepoint routine to change the guidepoint to current web position. 0: Accept the guidepoint to the current web position once the reset guidepoint routine starts and before the timeout expires.

Note that the value on this register is momentary. In order to change the guidepoint to the current web position, the user should first set this bit to 1 and then clear it back to 0 before the timeout. If this bit is never cleared back to zero, the guidepoint change will not be accepted by the controller.

Note that the remote guidepoint reset can be done only when the controller is in manual mode and when the Remote Control bit (bit 8) is set to 1.

15 0/1 Reverse Error 0: Standard Error Polarity Polarity 1: Reverse Error Polarity

WARNING: All the remote control operations may cause the web guide to move without operator intervention. This process may cause process upsets. Caution must be exercised when performing these functions and should be done by those who completely understand the consequence of this change.

WARNING: Web Guiding System enabled by SCU5 controller is an automatic control device that may stop and start at any time without notice, especially when controlled remotely. Hence standard safeguards must be in place to prevent any kind of injury.

WARNING: The remote control options provide significant access and control of the web guide and the sensor. A combination of the settings may create conditions that might not be ideal for web guiding. Hence only personnel familiar with the web guide operation should program the remote control interface. Contact Roll-2-Roll Technologies’ technical support team for any question or assistance.

WARNING: If Reverse Error Polarity is set on the SCU5 controller while the bit 15 is cleared on the PLC, a power cycle will cause the controller to revert back to Standard Error Polarity. Please set or clear the bit through the Ethernet interface to ensure proper operation.

Guide point offset register If the 13th bit of the web guide command register is set, then arbitrary guide point adjustment can be made by writing a 16-bit signed integer value to the guide point offset register. The offset value is the distance from the desired guide point location to the middle of the sensor window. A positive offset value will result in a guide point location towards the right half of the sensor window while a negative offset will result in a guide point location towards the left half of the sensor window. The guide point offset in mm = 0.0635*(the 16-bit guide point offset register).

Actuator speed register The positioning speed of the actuator can be changed by setting the 15th bit of the register to 1 and writing a value between 0 and 100 in 7 remaining most significant bits. If the 15th bit is low then the value written in the remaining 7 most significant bits will be ignored.

Actuator acceleration register The acceleration of the actuator can be changed by setting the 7th bit of the register to 1 and writing a value between 0 and 100 in the 7 least significant bits. If the 7th bit is low then the value written in the register is being ignored.

Application Page Number When this register is set to zero, the default register map is loaded. When this page is set to one, the web guiding specific register map is loaded. Specifically, the WORDS 12 and 13 in controller output registers will provide actuator parameters, actuator position and the controller information. Please refer to their output definitions in the controller output description.

WARNING: Please ensure that the application page change is indeed accepted by the SCU5 controller by verifying the appropriate bit checks in the Controller Output Registers. Specifically, check to ensure that bit 15 and bit 14 are set to 1 on WORDS 12 and 13.
