SA Project - Info Zone - Interlock Permissives

Chris

Hello,

Wondering if there is a way to add simple permissives to this list without needing to add Equipment References. I have permissives in PLC logic that I have an Equipment item (DIGITAL Tag), and simply would like to configure a list here. Those PLC permissives are sometimes based on complex calculations performed in the controller and can't be tied to a simple, "Valve is opened", "Temp is above the Low Limit" types of references.

Thanks,

Chris

  • Hi Chris,

    So are you saying you have an interlock which is between and Equipment and other factors rather than another piece of equipment?

    So like: PUMP001.ComplexCalcItem -> PLC logic

    If so, I guess you could "interlock" to yourself for that purpose?

    e.g. PUMP001.Running -> PUMP001.ComplexCalcItem.

    I think that would work.
