0x101B Collective Diagnostics Message for I/O
Modules
If a diagnostic alarm is activated (register 0x1134) and there is a diagnostic message for a
module, it is indica
ted here with a set bit. A module’s slot position corresponds to its
position in the 64-bit data field (minus passive modules without slot recognition). Example:
0x0000 0000 0000 0002 = There is a diagnostic alarm for module 2.
Reading the module’s diagnos
tic memory (0xAXXX) confirms the diagnosis and resets the
corresponding bit. In case of multiple diagnoses for one module, only the most up-to-date
diagnosis is displayed. The next diagnostic is then placed in a wait loop and only becomes
active once the current one has been confirmed.

0x101F Collective Process Message for I/O
Modules
If a process alarm is activated (register 0x1133) and there is an alarm for a module, this is
indicated here with a set bit. A module’s slot position corresponds to
its position in the 64-
bit data field (minus passive modules without slot recognition). Example: 0x0000 0000
0000 0002 = There is a process alarm for module 2.
Reading the module’s process alarm memory (0xBXXX) confirms the alarm and resets the
corresponding bit. In case of multiple process alarms for one module, only the latest alarm
is displayed. The next alarm is then placed in a wait loop and only becomes active once the
current one has been confirmed.
