OSCAT blinds and automatic calibration
« am: 26. März 2021, 11:59:58 »
I'm using OSCAT library to control blinds. My PLC is PFC200 from Wago and I'm using e!Cockpit. Everything works fine but I would like to get rid of automatic calibration after power failure built in the BLIND_CONTROL_S function block.

As it is written in the last sentence the "The automatic calibration however can be prevented if both inputs UP and DN are FALSE". And it actually stops the blinds to be calibrated (basically moving up and then down) but afterwards I can't control the blinds any more - UP and DOWN buttons are not working.

I was trying almost everything with no luck. With such an approach buttons works fine:

BlindControl(
    UP := BlindSecurity.QU,
    DN := BlindSecurity.QD,
    S_IN := BlindSecurity.STATUS,
    PI := BlindSecurity.PO
);


But in this case, there is an automatic calibration which I don't like. All blinds are going up and then down. I'm going to move into a new house within a week, I will be modifying my program a lot a the beginning, I don't want the blinds to move with each download.

Witch such approach the calibration is turned off (as suggested in the last sentence of the documentation):

BlindControl(
    UP := FALSE,
    DN := FALSE,
    S_IN := BlindSecurity.STATUS,
    PI := BlindSecurity.PO
);

BlindControl.UP := BlindSecurity.QU;
BlindControl.DN := BlindSecurity.QD;


But then buttons don't work any more.

Maybe I'm using outdated libraries. Where I could find the latest OSCAT Basic and OSCAT Building libraries for Wago e!Cockpit? Were there any updates in the last few years?

I don't speak German at all...
