DIO module – Sudden issues with output – red powe led on Out LED – needs help for debugging
Posted: 14 Feb 2020, 00:55
Hi everyone,
While building prototype of a new system I have encountered issues with DIO module.
After some time using, LED for Output power on DIO module got RED and output pins stopped working. (you may find full kern.log attached)
Everything was well-connected and was working. Output pins stopped responding during the test of a system.
Can someone please help me trace root cause of this issue? I can’t get it to work again. Tutorial page states that red status of LED indicates “No power supply to the outputs on the plug X2 or overloading.”.
Are there any fuses (including timer fuses or software fuses) on output pins that might be affected in some way? I'm starting to doubt that a part my DIO module got defected or surged in some way...
Input pins still work normally - I can read status of switches on my panel.
I probed voltage and connections, everything is still connected.
I'm using latest software, BUT i'm also unable to update firmware on DIO module:
Error on firmare update:
Any ideas on where to look next? Any feedback is welcome
Additional info about my setup:
DIO module on the left of Core3+ module.
I’m using MDR-60-24 to power DIO and Core3+ modules. Power supply on the left is for DIO and Core modules only. Power supply on the right side is connected to relays and 24v power socket in the middle, but those are not in use and are fully isolated from DIO/Core system.
3 output pins are connected to 24v control lights, 3 inputs are connected to switches, same power rail as +v on core module. You may ignore rest on the photo...
Here’s a photo of a system.
