Hi,
I have a 750-881 controller that was working fine with Codesys 2.3 connected by ethernet connection.
Until the PC running codesys did rebooted while it was logged in. It could be the power was cut-off for a short while but not sure.
Now the NS LED on the 750-881 is blinking green (from the doc, it means no connection (Modbus/TCP or ethernet/ip)) and I get a connection error when I try to login. However, I can still access the 750-881 via the webserver and the settings and status seem fine.
Any input on how to re-establish the connection ?
So your PC with codesys rebooted or the 881 rebooted ?
