Dear Community,

How does one link an HMI element to a bit in a manner where the bit is only true for the duration that the HMI element is held to touch? In visilogic I used the HMI link to bit and then linked that bit to a TON timer. To reset an hour meter numeric element the operator would press and hold the HMI element for 5 seconds, the timer would go true, a PTC contact would trigger a RESET NUMERIC coil; then Happy, happy, happy. Now not so much. Is this achievable in UniL? Actions seem to be latch oriented. Thanks All.

Sincerely,

OK, did not realize the two opposing forces could work together as a "bit true for duration of touch".  Setting up two lines on actions: set bit pressed, reset bit released works exactly as desired. Thank you Saragani!
