QJ71MB91 modbus to Fx-3u 485adp

[madhan]

Hi all ,

I need to communicate Qseries plc with Fx series using modbus where Q series is the master and Fx will be slave,

1. I need to send data from Fx to q series plc , already set the communication parameter to Fx cpu and slave address I want to know how to set head address and how to call the device head number in q series plc 

2.How to send data to the device head number in FX plc

3. How to connect wiring I already have devices connected as slaves in Q series which are working fine  when I try to add this Fx cpu the communication between other devices affects sometimes they dont read data or read some data I dont get what is happening

 

Thank you
