Hi,

I am using TRB 140 as a master and Siemens S7-1212 C PLC as slave. I am able to fetch data from PLC by MODSCAN but not able to fetch data by TRB140.

Hello,

This is a known issue related to modbus_tcp_test application used by the gateway.

MODBUS is currently undergoing a major rework, which should solve the issue you are experiencing. Updated MODBUS iteration will be included with upcoming 7.3 firmware.

Best regards,
