I am declaring one Fatek PLC as Master and other as slave but the data is not transmitted between them, i can't understand the data address declared of slave as〜, i am stuck here, can anyone help me out.
make sure you have the exact Boud rate ,even /odd parity on both Master and slave then make sure of Polarity Data+& Data -
if it is not working try to test evey PLC alone with your computer and RS-485 cable to check what is the problem or if you have HMI use it to read the internal register with each one of them
Configure the communication parameters (Baud Rate, Parity, Stop Bits) first, check Data (+) & Data (-) cables termination, Device ID (address) to be provided for Slave.
If everything was good, check with Modscan software first, if u are able to read the register values.
