Hello,
I need and advice with modbus RS485 issue,
Im not able to control addresses 65-72 through group objects, RX TX LED on Slave device flash only when I link our group object to the RTU adress, and it updates to correct value, so register is fine, I'm just not able to rewrite it - LM doesn't allow me to, it won't send anything to the RTU, adresses in Slave device are R/W, I have allowed this GO to write to the bus.
Can we somehow allow Logic Machine to write values to these 7 adreses? RTU Device allows us to control these parameters from modbus. Do we need some kind of script for that?
Thanks!
