Slow press gives the rear block longer to be late. Fast press hides it.

RE: TLS3-GD2 guard lock releases a second after Stop while the spindle is still coasting

And the timer lives in the safety task, not the standard one.

RE: CompactLogix 5069 misses a 5 ms reject pulse from a checkweigher, fine in Emulate

You could put the reject rung in a periodic task at 2ms and drop the RPI on that card to 1ms, the 5069 IO goes that low if I remember right. Still pol...

RE: 1756-IF8 reads underrange with a new 2-wire 4-20mA pressure transmitter

The IF8 doesn't source loop power. Some analog cards do, pretty sure the IF8 isn't one of them.

Correct. THRSe has no sync time parameter, as far as I know it's fixed inside the instruction at 500 ms for that reason. Fault code will be the discre...

Firmware and Studio version? And what's the continuous task scan, Controller Properties, Tasks tab, Max Scan Time. Also is it a plain 5069-IB16 or the...

RE: GuardLogix THRSe two-hand control faults on sync unless both buttons hit together

Which fault, the THRSe has a few and they show in the instruction's fault code online. And what do the four inputs do when you press each button alone...

RE: Conveyor PowerFlex 525 won't restart after an e-stop until the run bit is toggled

Added the AND. E-stop, reset, conveyor restarts on its own. Second shift ran it through a dozen e-stops, fine every time. The run bit that never drop...

What does the risk assessment say about access while the spindle is rotating? That decides whether a validated time delay is acceptable at all, or whe...

RE: 1769-L33ER major fault T04:C20 array subscript too large, once a shift

Controller's fine. Recipe[20] means elements 0 to 19. What is Idx when it faults? The fault log won't tell you but the HMI will: what does the operato...

RE: 12 zone accumulation conveyor in a CompactLogix, twelve copies of the same zone rungs

Figured zone 12 would be the odd one. 100ms over a MSG sounds right.

RE: Consumed tag error 16#0127 invalid connection size after editing a UDT

Did you download the new UDT to the downstream controller too, or only upstream? Both on 32.011 or whatever you're on?

RE: 12 zone accumulation conveyor in a CompactLogix, twelve copies of the same zone rungs

One AOI for the zone, an array of zone UDTs, called twelve times. The rule "run if the next zone is clear" lives in the AOI once and the delay lives i...

RE: Conveyor PowerFlex 525 won't restart after an e-stop until the run bit is toggled

F059 on the e-stop, reset clears it. Looked at the logic on the three good ones, their run bit is ANDed with the safety OK bit so it drops on the e-st...
