Hello, everyone,
I want to connect a touch screen (Fuji's or Easyview's or Digital's) to GE FANUC 90-70 PLC using RS485, but not successful. When i use 90-30 PLC, the communication can be built well.
From the view of serial communication (as I know), the only diffirence between the two PLCs is that 90-30 uses SNP & SNP-X protocols, while 90-70 uses SNP only.
Can anyone give me some information?
