Response of the ET 200M
The IM 153-x reports via diagnostics the removal of a module. The diagnostic event
corresponds to the removal interrupt. The IM 153-x also enters the removal of a
module in the module diagnosis.
When inserting a configured module, the IM 153-x deletes the entry in the module
diagnosis, so that the module is not addressed by the IM 153-x. If the ET 200M is in
user data mode, then the IM 153-x reports a diagnostic event in accordance with the
insertion interrupt. The inserted module is configured accordingly and assumed in the
ET 200M. Any parameters for the module transferred from the user must then be
transferred again from the user to the ET 200M.
The IM 153-x ignores the inserted module.
The IM 153-x reports a diagnostic event in accordance with the insertion interrupt.
In the diagnosis the entry remains after the module has been removed.
