I've tried to control my Eheim 350 with PLC 5.0.5.4, but it seems it doesn't respond on commands whatever I do. May be my settings aren't correct:





When I put the filter in manual mode (by using the buttons on the filter itself) a minute later, the filter turns back into automatic mode and LED's 4 and 5 starts flashing for about a minute. It doesn't mater if the "An Eheim controller is connected" is checked or not. After a second try the error didn't came back.



According to the user manual it means there's an electronic error:



So, does GHL know what the problem is or was?
Nevertheless, I still can't control my filter by using PLC..
