Issue is a revision mismatch between the ESI and the ctrlX IO XB-EC-12 bus coupler firmware.
XB-EC-12 FW v1.0.0 or v1.2.0 have revision 0x0000_0100
XB-EC-12 FW v1.4.0 has revision 0x0001_0100
ctrlX IO Engineering v1.12 cannot handle this two diffrent revision in the ESI, issue doesn’t happen with ctrlX Works v1.20.0 or later.
You have two options to solve in ctrlX Works v1.12
Remove latest ESI and switch to older version, like XB-EC-12 ESI from ESI package v1.8.2
Firmware update of the bus coupler XB-EC-12 to latest firmware FW v1.4.0
Both, the ESI package and firmware you can find in Downloads section.
