MVP 2022 Flex727 Posted January 3, 2019 MVP 2022 Report Share Posted January 3, 2019 Make sure your V200-18-E46B Snap-In module is firmly attached and secure. Quote Link to comment Share on other sites More sharing options...
MVP 2022 kratmel Posted January 3, 2019 MVP 2022 Report Share Posted January 3, 2019 I test on V1040 + V200-18-E46B hardware - started with no problem. 8 hours ago, Flex727 said: V200-18-E46B Snap-In module is firmly attached and secure. Maybe problem with sensor configuration or connection. Panel installed on machine or tested separately? Is it any VFD or not suppressed contactor coil present in control box?

Emrah AKAY Posted January 4, 2019 Author Report Share Posted January 4, 2019 All the sensors are very quality and 4-20 mA. Its made from eurpe. and snap IO is firmly very much. And use in panel equipmant; 8 piece selenoid valve 24VDC and power supply with nonstop UPS. There isn't any VFD and Contactor... Quote Link to comment Share on other sites More sharing options...

MVP 2022 kratmel Posted January 4, 2019 MVP 2022 Report Share Posted January 4, 2019 Maybe it is battery issue. Time and date on panel is not current. ??? Quote Link to comment Share on other sites More sharing options...

MVP 2022 Joe Tauser Posted January 5, 2019 MVP 2022 Report Share Posted January 5, 2019 14 hours ago, kratmel said: Is it flyback diode installed on solenoid cirquit? This is most likely the source of the problem. The screen you are seeing is what happens when an inductive pulse finds it's way back into the I/O module and kicks the PLC's watchdog timer out. As kratmel suggests, install reverse-biased diodes across where the solenoids are connected to the I/O module. It's probably happening when you release two or more solenoids at the same time. Look at this post- http://forum.unitronics.com/topic/2735-flyback-diode/ And here's an explanation with pictures- https://en.wikipedia.org/wiki/Flyback_diode Joe T.
