ABB DCS alarm appearing.
Please tell me what could be the possible causes of these alarms appearing together:
_ SL_153_2_DIG FAULT FOR MODULE 24
_ SL_153_2_DIG FAULT FOR MODULE 04

I doubt it's direct I/O's must be remote i/o's over profibus, "SL_1F3_2" is tag name of profibus slave object. Sounds like there is fault on SL_1F3_2 slave or there is fault on connected I/O module.
Check in system display in HW tree or if you have engineering station access , Find this tag via taglist and cross reference in HW tree in commissioning mode. there you can trace out what and where is fault. Check in HW tree.
