Hi experts,
I have a system that using A2A PLC connect to 2 HMIs of Proface GP 2000 series using module A1SJ71UC24-S8. The module used RS422 interface to connect to HMI. And they used multilink n:1, means 1 PLC - n HMIs. Attachment shows how they are connecting. My client just wants to upgrade to Q series and not to change the HMIs. I think I should replace the A1SJ71UC24-S8 by QJ71C24N. I can conect PLC to HMI by configuring 1:1. But then, when configuring n:1 (means 1PLC : 2HMIs), HMIs can not connect to PLC.
Have anyone here ever configured the multi-link n:1 between Mitsubishi Q PLC and Proface HMI GP 2000 series? Please help me
