Sorry with my english.
I am a beginner in PLC or HMI, so far I only connect plc & hmi which from one brand ...
I currently have Omron CP1E-N40DR & HMI GP4301TAD (proface), but already last one week I am confused to communicate both devices ...
I'm sure this is not a problem with cable communications because I made it according to the pins in the manual.
Please help me
