Configuration

Introduction
The IM 467/IM 467 FO is configured with STEP 7. The configuration data are retained even
in the event of a power failure; a memory module is not required. Using the S7 functions it is
possible to program and configure remotely all the IM 467/IM 467 FO connected to the network
and all the CPUs connected via the SIMATIC S7-400 backplane bus.
SIMATIC STEP 7, version 5.00 or higher is required.
Module replacement without a programming device
The configuration data are stored in the load memory of the CPU. The non-volatile storage of
configuration data in the CPU is ensured by battery backup or EPROM module cards.
The IM 467/IM 467 FO can be replaced without the need to explicitly reload the configuration
data.
It is only possible to remove and insert the IM 467/IM 467 FO in a de-energized state.
Multiprocessor operation
The connected DP slaves can only be assigned to and processed by one CPU.
Configuration and diagnostics cannot be carried out simultaneously
When configuration is in progress, the IM 467/IM 467 FO cannot be diagnosed at the same
time via MPI.
Note
The transmission rates 3 Mbit/s and 6 Mbit/s are not approved for IM467-FO.
