Hi Skate, Well, the purpose of the permit is that you may not activate the valve (close, open) in CFC/SFC or operator command. If you have SafePos=1, the valve will be controlled to open position-> Ctrl=1. When Permit=0, it is not allowed to give the open or close command. I think this is working just fine. You don't need Permit_Open or Permit_Close, because the Permit functionality does not work when the valve is activated. It only works, when the valve is in neutral position (not activated).

I disagree. You can control in the safepos direction even if permit is 0! |

How did you set Permit=0??? Just by setting the "Value" to "0"without a interconnection to Permit? Or did you connect a OpDi01 for example? If you just set the Value to 0, then it won't work, because the signal status is not valid...You have to set the signal status to 16#80 as well. |

Hi. There's a similar thread but about the MotRevL block (different interlocks for two directions). PCS7 V8.0 APL MotRevL Interlocks |
