Commissioning and Diagnostics
Removal and Insertion Interrupts
To remove and insert modules during operation, you must configure the ET 200M
with active bus modules (see Section 4.1.4 in the manual). Use the switch for the
removal/insertion interrupt to parameterize whether removal/insertion events are to
be reported as interrupts in the diagnostic frame. If you disable removal/insertion
interrupts, you can still remove and insert modules in the configuration with active
bus modules. These events then appear in the module diagnosis and the module
status exclusively. See also Section 9.1 and 9.2 to find out how the older IM 153-x
versions respond.
In a configuration without active bus modules, removing and inserting modules will
result in station failure.
Note: Inserting or removing a DM 370 dummy module does not trigger an insertion
or removal interrupt.
Diagnostic Interrupt
If there is a diagnostic event for channel/channel group 0 of a module, there may
be a module error as well as a channel error (see record 0 in Figure 6-11 on page
6-32). The entry is made in this case even if you have not enabled the diagnosis
for channel/channel group 0 of the module.
