Hi all,
I’m having some problems regarding a digital input from a remote ethernet coupler input.
My setup contais an Omron CJ2M cpu33, a switch, an Omron NS5 HMI (also ethernet) and 10 Wago Ethernet/IP couplers, all of which have 2 digital in- and 2 digital output cards.
Every machine cycle all couplers recieve an input from a regulair proximity switch, this signal is high for about half a second and switches at a frequency of about every 2 seconds.
Despite the fact there’s no high speed stuff going on here, the pulses are not processed properly. Monitoring my program I can see that the inputs are skipped and somtimes are not processed even for several machine cycles.
Is my network too slow, can it be a scan time issue, or something else.
I’ve come a long way building this system but I’m still fairly new to plc programming.
Hope someone has a suggestion.
Best regards,
Andy
