FAQ

The STB EHC 3020 is exclusively designed for the Schneider Electric Advantys STB distributed I/O platform. It connects to an Advantys STB Network Interface Module (NIM) which then communicates with a master PLC over various fieldbuses like Modbus, CANopen, or Ethernet.

This specific module, the EHC 3020, is an incremental counter. It is designed to count pulses from single-channel (A-phase) or dual-channel (A/B phase) incremental encoders. It does not support more complex modes like quadrature encoding for direction sensing out-of-the-box, which would typically require a more advanced module.

Configuration of the Advantys STB island, including the STB EHC 3020 module, is typically done using Schneider Electric's Advantys Configuration Software or within the programming environment of the master PLC, such as Unity Pro or SoMachine, depending on the network and controller used.
