Split from connecting omron hmi to s7-300 cpu.

Hello,

for first check web page for your expected product for support (PDF from OMRON page):

OMRON HMI specifications

Next attachment for sure. You need on OMRON set correct driver for Siemens S7 PLC probably. I expect here maybe use of also RS232 side of PC Adapter no USB adapter type but be careful with pins on both devices. There is also Modbus as general protocol but then you need have also special serial CP attached with more things to buy what can be little bit problematic.
