Short Answer
Each SCU5 or SCU6x controller processes two independent sensor channels—one Master and one Slave.
Both SCU5 and SCU6x controllers support two independent sensor channels, enabling single-controller Master/Slave configurations:
- Channel 1: Master sensor (monitors reference web position)
- Channel 2: Slave sensor (provides feedback for the guided web)
For multi-slave applications (3+ webs), the Master signal can be broadcast to multiple Slave controllers via industrial Ethernet (EtherNet/IP, PROFINET, EtherCAT, or Modbus/TCP). This enables scalable synchronization—one Master can drive any number of Slaves without mechanical complexity.
