IO forcing operator lock out

[rjtechserv]

We have machine operators that have learned how to force IO ON/OFF when we don't want them to but, don't mind them viewing it.

Is there or could there be a way to password protect IO forcing as you protect the Machine Parameters?

Assuming that you have wired the control so that it does not depend on any inversion or forcing for normal operation (e.g. you have used N.C. sensors where the PLC expects them), then you could edit the PLC program to either remove the inversion and forcing features from LoadParametersStage, or you could set it up so that those features are only enabled by a non-obvious parameter setting, key combination, or input closure.

Look in your PLC program for a block that begins with a reference to SV_ENABLE_IO_OVERRIDE.

Thanks Marc, I'll drive into that and see what I can figure out.
