Hi,
I’m using a QJ71MB91 modbus card in a Mitsubishi Q series PLC. It’s being used as a slave, and everything’s working fine aside from the error light.
When I unplug the modbus connection (port 1) the error light sometimes comes on when I reconnect. It’s a genuine error being caused. When I open the system monitor in GX Works 2, I can view the modbus card status and there is a button to reset the error, which works ok and the error LED goes out.
What I’d like to do is the same error reset from the PLC code, that way it could be linked into a reset button on SCADA.
Anyone know if it’s possible, and how to do it?
Thanks for any pointers....
