Hi All,
I am trying to communicate siemens PLC with FESTO Servo & 3 Festo make Steppers on FHPP Modbus Protocol. Sometimes, I face Modbus timeout messages at Servo drive though i ve been clocking the Client blocks at a minimum intervals. Once the modbus connection is timed out @ servo drive, i have to take out the cable or reconnect or re-start the system.


Has anyone faced errors like me while connecting 4 devices with siemens PLC on FHPP Protocol?:rolleyes:
