Hi All,
I am trying to set up the communication between a G304K200 and a Siemens S7-226 PLC via serial PPI but it is not working and I did a quick search seem there is no detailed guide on it.
I made a lead following the pinouts of a CBLSIE01 cable.
PLC Side
1 Txb
2 TxA
6 COMM
HMI Side
3 TxB
8 TxA
5 COMM
In the HMI program, I selected RS-485 with S& via PPI Version 2 as the driver with default port settings.
Baud Rate: 9600
Data Bits: 8
Stop Bits: 1
Parity: Even
Port Mode: 2 wire rs485
Can someone point out what I am doing wrong here?
