Hi everyone,
I'm trying to communicate a MultiPanel MP277 touch screen (from Siemens) with a Modicon PLC (984), so, I built the proyect on WinCC Flex I choose a Modicon PLC as a drive, then I connected an RS422/RS232 converter to the MP (the converter is from siemens 6AV6671-8XE00-0AX0), then I've the cable wich is also a siemens, it's a 6ES7901-1BF00-0AX0 and then I have the PLC.
The thing is that I'm not having any communication, is like if the MP is not seeing the PLC. I'm not shure if I've everything OK or if I'm missing something.
Hope someone can help me.
Thanks in advance.
Juan
