Probably a counter. One-shots belong in front of counters, not timers.
Scan default, almost certainly. Nobody picks SM-Synchron for a gantry on purpose.
Drag chain rated cable in, one run, no joints in the carrier. CRC on 14 A stayed at zero over two days, no SAFEOP, no lost frames, no following error ...
Yes, steps and transitions, the boxes. Split it. The sequence goes in SFC or an integer state machine in ST, one place that says which step and why it...
You're still sampling, so there's always a window. Three ways that actually close it, any brand. Put a pulse stretching relay between the checkweigher...
Browse wrote 1,1,2,192.168.10.12,1,3 and the MSG went .DN first scan. 50 DINTs, 20ms or so round trip on a timed trigger. So my typed path ended at s...
Not sure why 20ms specifically was chosen back then, but 23ms of work in a 10ms task is the problem, not the watchdog. Even at 500ms you'd overlap eve...
You're choosing between two ways of not bounding the loop. Bound it. A FOR has a fixed range and finishes in one scan no matter what the data is: ```...
Reset the counters. One shift later, CRC on slave 14 port A is 312. Slave 13 port B zero, everything else zero. I've replaced the 8 m cable with a spa...
OB121 decides what the CPU does when the error happens, it doesn't stop the error. On the 1500 the default without OB121 is already to keep running an...
No status bit, nothing went wrong. Same in TIA, same in C. 0.1 in binary is a fraction that never ends, like a third in decimal, so the controller sto...
Then the counter's fine and the input filter is eating your pulses. Device configuration, CPU properties, DI 14/DQ 10, Digital inputs, Channel 0 and C...
There is your 300 ms, the loop, not the panel. 4000 UDT compares in one scan is a lot of work in OB1 and it lands on top of everything else, which is ...
It does. A one-shot makes the rung true for exactly one scan. Your TON gets one scan of enable, accumulates a few ms, then the rung goes false and a T...
OTL and OTU would run, but you'd end up with two rungs deciding one output and nothing on the rung telling you why the motor's on. Same rule in every ...
