Hello,
I am trying to connect a S5 115U CPU943B to an OP277 panel. I have been through the "HOW TO connect and configure a WinCC Flex panel to an S5 PLC via the PG port" which I got from internet and have already procured the TTY-RS422 connector.
I have also build the cable, as instructed, on the manual of the TTY-RS422 connector and connected it as it says on the manual (which I have attached). HAve configured the IF1B of the panel as RS422/RS485 (1-off, 2-On, 3-On, 4-Off). HAve set up the connection in the project as Simatic AS511, IF1B 9600 Baud, Even Parity, 1 Stop bit and the CPU as 115U 943. HAve created two tags to DB235. But when testing the connection it is not communicating (the OP277 show ####).
As a test I have created a RT project for PC and used the TTY-232 cable with My PG and everything is fine, so the PLC is communicating.
My Questions is:
HAs someone build such type of project before?
Has anyone been able to get this communication to work?
What have I done wrong for this communication?
What can I do as more test to know where is the problem
I do not know if anyone can help me with this issue, but I would be very greatful for any kind of help.
With Thanks,
Vish
