Unlatching coils

2 posts in this topic

Is it possible to unlatch a latched coil in ProWorx 32? My program latches a coil upon completion of a timer, but I need to unlatch the coil on the activiation of an input. When the timer loses power at the input, the output de-energises, which is not suitable for my application, hence the use of a latcing coil. Thanks in advance, Richard Byrne.

Write your own latching relay... When the timer completes turn on a bit, and have that bit latch itself on until the input is pressed. If you're looking at the (L) output in the software, that's not latched in the sense that it's locked on, it just means that it's state is backed up and restored by the PLC after a power failure. See code below...
