- Set System Memory #234 for communication conditions of PLC (JW30 Communication port1: RS422), 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: RS232C, RS422), 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 Configuration - System Setup - Project - Host I/F Driver - transmission wait of WindO/I-NV2.
Confirm the manual. (chapter of a communication port) of PLC about whether a transmitting wait setup need to be
adjusted.
- Refer to “New Satellite JW manual “or “New Satellite JW Link Unit manual” for details.
