My company is commissioning a new machine and we're having a few issues with I/O Channel errors. My Italian colleague took a screen shot for me to show me what it's doing.
Setup:
PLC - CPU-1515F-2 PN
Drives - S120 CU320-2 PN
- Smart Line Module (project says ALM, but is actually SLM)
- 4x Single Motor Modules
Here's the catch, the I/O channel errors only show up on the CPU side, there are no active faults on the CU320. The channels that pop up for the error (2, 6, 10, 8 in the screen shot) are not always the same. The errors don't affect functionality at all, only shows a SF on the CPU. The errors pop up as soon as we power on the panel and we aren't able to Acknowledge them. The bottom 5 alarms (ModuleAccessPoint faults) come on with the CU320 and 24v being powered on, it seems like the I/O Channel alarms come on once the MCC is pulled in (hence the 30min time difference between alarms)
What I've done to try to resolve:
1. Double check topology
2. Double check safety I/O addresses
3. Double check safety telegram and F-Addresses
4. Tried a few different ways for "ACK_GLOBAL" to work
Any help would be greatly appreciated!
