In out RT240 i have configured an Modbus TCP Master to read registers from a PLC Modbus Server. Depending on value in the register the alarms sending certain SMS.
The Period of reading registers is defined with 60s. Timeout is 30s. All works quiet well after switching on the systems. Unfortunately, after a certain time it seems Modbus TCP Master stops working.
Our RT240 is running with the Firmware RUT2XX_R_00.01.14
Has anyone an idea?
