RE: PanelView Plus 7 on the cartoner went slow the day Ignition was connected to the L33ER

Not the switch. 6,800 tags every 100 ms is 68,000 tag values a second off that embedded port. The driver packs them into far fewer packets than that, ...

RE: Motor current into a CompactLogix via CTs for predictive maintenance, is it worth it

RE: Modbus TCP through a serial gateway, exception 0B or no reply from every slave

RE: Ignition 8.1 Logix driver faulted on a 1756-EN2T, CIP connection request error 16#0100
