How to control a Robotiq gripper with a PLC?

Sometimes some customers want to control the gripper directly with a PLC, this is something possible but we don't support this case.

The most important is that you make sure the PLC has the necessary communication protocol and that the software makes it easy to read and write the Modbus register of the gripper.
Modbus communication from a PLC is very common.
 
The native communication protocol of our grippers is Modbus RTU.
 
However, you can use different communication protocols in combination with our universal control:

  • [UNI-CTR-001-CANO] External controller for Robotiq Device -- CANopen
  • [UNI-CTR-001-DNET] External controller for Robotiq Device -- DeviceNet
  • [UNI-CTR-001-ECAT] External controller for Robotiq Device -- EtherCAT
  • [UNI-CTR-001-ENIP] External controller for Robotiq Device -- Ethernet/IP
  • [UNI-CTR-001-MTCP] External controller for Robotiq Device -- Modbus TCP
  • [UNI-CTR-001-PNET] External controller for Robotiq Device -- ProfiNET
