Controlling the Operating Mode
There are two ways to control the operating mode of the IM 467/IM 467 FO:
• By using the mode selector
• By using the programming device/PC
Mode Selector
You can switch operating modes as follows using the mode selector:
• From STOP to RUN
All the configured communication services and S7 communication services are
available in RUN.
The IM operating mode can only be controlled from the programming device/PC
when the switch is in the RUN position.
• From RUN to STOP
The IM goes into STOP mode. Any existing S7 connections are cleared down,
and the DP slaves are no longer supplied.
Loadable Firmware
The IM 467/IM 467 FO supports the updating of firmware (FW) by means of the
FW loader. The FW loader is a component of the NCM S7 configuration software
for PROFIBUS DP. Authorization is not required for this. After a FW update, the
central controller must be switched off and on again before normal operation can
be resumed.
Note
You can find additional information on loading firmware in the NCM S7 for
PROFIBUS DP manual and in the readme file of the NCM S7 for PROFIBUS DP
configuration software.
Note
An optical bus terminal (OBT) is required to load FW in the IM 467 FO.
