Changing Output

[Gerral]

I'd like to change the state of an output using my C# program but cannot figure it out.

I've tried using M95/M94 in a RunCommand but it doesn't seem to work with macros, or at least it's not changing the output.

Any ideas?

Thank you in advance.

CNCPipe.plc.SetIoForceState(int ioBit, BitType bitType, ForceState state) should do what you're looking for. You'll want to use BitType.Output and then either ForceState.ForcedOn or ForceState.ForcedOff

Works great! I don't know how I missed that in the documentation.

Thanks!

Presumably that will preclude controlling that output in any way with the PLC program, but as long as that is what you want, it is a reasonable solution.

More generally, outputs are controlled by the PLC program, and skinning applications send requests to the PLC program (e.g. via SV_SKIN_EVENT_nn) when they want the PLC program to turn a device on or off.

That way the PLC can still do its job of applying interlocks, turning devices off when an error or fault occurs, or allowing other methods of controlling the same device (e.g. jog panel keys or M functions).

thanks you may have made me realize one of my problems as my M94/M95 is no longer working even though I've "unforced" these outputs.

I'll change it to use the SV_SKIN_EVENT

Thanks!
