On the advice recently regarding tightening up modbus addresses to get communications to work, I changed my modbus addressing for one of my PLC's. The system is now showing communications( as in when i turn my PLC to halt it shows fail on the DCS side and when its running it shows running on the DCS side) , so there is communications there. However, its not writing the values across for the temperatures i'm logging. I'm new to this and i havent any idea why it wont communicate the values . I definitely have all the parameters set up right (the baud rate etc) , and all the modbus addressess are allocated correctly , but the values just arent coming through. I'm reading and sending them as the right type as well (unsigned integer)
Please help.
