My male-female extension cable for the TM171ADMI programmer got caught in a panel door and got broken. I am considering replacing it with a multi-port USB extender to enhance my laptop´s USB ports. Is it ok or it is better to keep it assigned to only one USB port ?
I should probably open another topic, but I am lazy today: I assigned a paddle flow switch signal to a TON timer input. The compressor is allowed to start only after the TON timer elapses (when Tmer.Q = TRUE),
I had a cavitation or maybe air in the hydraulic system which caused the flow switch to generate a random pulsed input (going back and forth from 0 to 1) which means the compressor was never allowed to start. This is the expected behavior but there is no alarm associated with that, so I actually was able to detect that because I got connected to the PC. Is there any easy way to detect something like this before I star thinking about timers, flip-flops and other stuff ?

Hello,
I've never tried, but I do not expect issues using a USB port extender.
About flow switch management you can try to use the FlowSwitchAlarm block available in the attached library:

Thank you.
There does not seem to be a FlowSwitchAlarm block available. You mean the configurable alarm block ? The LocalDigitalDebounce function would be able to filter this "noise" ?

This is the block I'm referring:
LocalDigitalDebounce could act as filter for glitch, but the flowswitchalarm FB does more than that

I see. This is a new release.
I had a previous one installed and it had less functions. Thanks.
