Good day,
I am so confused as I am a beginner.
I recently got PLC XGB DR30SU with communication module XBL-EMTA
All I need to communicate with wincc 7.2 using MODBUS TCP.
I need to display plc I/O status on wincc.
I failed to do that because I do not know how to define the addresses between PLC and wincc
Is there any ladder instruction at plc to send the PLC I/O status to a specific address that can wincc recognize?
Attached is the settings of modbus tcp at PLC software.
Thanks in advance.
