How To Connect NQ HMI To Omron PLC Using Hostlink Protocol
This article describes the initial connection between a NQ HMI and a PLC using Hostlink protocol.
For the example below a NQ3-TQ000B and a CP1L PLC will be used.
Cables required for a good connection are:
NQ-CN222 or NQ-CN521 to connect to CP1W CIF01 or directly to CJ1M PLC. For pin-outs of these cables look in the appendix of the introduction manual (V07-EN-0*). NQ-CN221 is also available for connection to the mini-peripheral connector for CJ1.
After connecting the correct cable to the communication will be established which will result in a steady Blue RUN led on the NQ.
Attached you will find a small sample application for NQ3 and Hostlink setting. In this program also CIO100 is used to display the value.
Also an empty PLC program (CP1L empty) for CP1L-L PLC is added for correct settings.
Downloading both NQ3 and PLC sample program to your hardware AND using the correct cable should result in a working data exchange between PLC and NQ3.
