- Set System Memory #234 for communication conditions of PLC (JW30 Communication
port1:RS-422), and set System Memory #235 for Station No..
- Set System Memory #236 for communication conditions of PLC(JW20/70/100
Communication port,JW30 Communication port2:RS-232C/RS-422 ), and set System
Memory #237 for Station No..
- Confirm the PLC manuals as the speed of Baud Rate may not use according to PLC.
- When connecting with the communication port of a CPU unit and making it communicate,
after receiving a response from PLC depending on the model of PLC, while MICRO/I
transmit data, some which need waiting time are.
- In this time, please adjust [File]-[Project Settings]-[Host Port]-[transmission wait] of
WindO/I-NV2.
- Confirm the manual.(chapter of a communication port) of PLC about whether a
