4.5.6.1.2 Compatible module is added again when the bus connection is active
If a compatible module is inserted into the slot of a previously removed module during an
active bus connection, the IM 053-1EC01 behaves as follows:
1. Entries are made in the history object of the IM 053-1EC01:
n Module was plugged.
2. The System SLIO backplane bus is refreshed.
3. The coupler can only be brought to the state Op by means of a State-Change-
Request.
ð
In the state Op :
n The SF LED turns off.
n The RUN LED lights up.
n The process data communication is restarted.
4.5.6.1.3 Incompatible module is added again when the bus connection is active
If an incompatible module is inserted into the slot of a previously removed module during
an active bus connection, the IM 053-1EC01 behaves as follows:
The System SLIO backplane bus is refreshed.
ð
Since a difference between different modules of the same I/O length is
detected, the SF and RUN LEDs continue to flash.
If an incompatible module is inserted into the slot of a previously removed module during
an active bus connection, the IM 053-1EC01 behaves as follows:
The System SLIO backplane bus is refreshed.
