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

It isn't the rate, it's the width. The input image gets read once per scan. Your scan is 12 to 20ms and the pulse is 5ms, so any pulse that starts and...

RE: TwinCAT 3 EtherCAT slaves drop to SAFEOP, WcState 1 and lost frames climbing

About 8 m, from the last EK1100 in the main panel to the coupler in the gripper panel. Standard EtherCAT cable, the green stuff, and it runs through t...

RE: 30 step filling sequence, ladder is 400 rungs of state bits, move it to ST or SFC?

RE: Gantry axes on EtherCAT drift apart over a long move, TwinCAT distributed clocks off

What are the drives running in, DC-Synchron or SM-Synchron? Each AX8000 has a DC tab in TwinCAT. A ramp that grows with the move and resets when it st...

RE: CompactLogix reboots whenever a bank of solenoids fires

The coils say 24VDC 0.21A. So 8.4A if all 40 fire at once, plus the PLC and the rack and the HMI. That's over 10 isn't it.

RE: CompactLogix reboots whenever a bank of solenoids fires
