Modbus tcp-ip problem
#4
I am using a Eliwell. Do you know it?

There is another strange think. As you can see I use 2 variable of the same register (16391). One only readable and the others writeable. For one I used value multiplier 0.1 and the other multiplier is 10. Because PLC use 200 for 20 degress. Hence when I sent by HL the value is multiplied of 10 but when plc send its data (in this case is a temperature setpoint) . Everything works fine but sometimes it seems that values is multiplied by 0.1 instead 10 and viceversa the others. What do.you thibk about that?
Thanks.
