The new functions for the IM 153-4
Media redundancy
Function for ensuring the network and system availability. Redundant transmission links (ring topology) ensure that an
alternative communication path is made available if a transmission link fails.

Shared device
The "Shared Device" function allows the submodules of an IO device to be divided up among different IO controllers.
The following conditions apply for an ET200M if it is to be operated as a shared device.

) manual.
The following applies to the ET 200M:
●
If an IO controller fails, the entire IO device outputs substitute values. This means that not only do the IO modules of the
failing IO controller output substitute values, but also the IO modules of the intact IO controller.
●
Since the outputs of an IO module cannot separately output substitute values, in the shared device environment the I/O
will only output process values if both IO controllers are in RUN.
As soon as an IO controller is in STOP mode, the outputs of that IO module that are subscribed by the other IO controller
will therefore output substitute values. This fact must be taken into account, for example, for the STEP 7 functions,
"Modify" and "Force". With the STEP 7 "Modify" and "Force" functions, a CPU in STOP mode will be reported as being in
RUN mode. This releases the modules that are assigned to the other controller that is still in RUN.
Configuration as Shared Device
"IM153-4 PN ST as of V3.0 Shared Device" or "IM153-4 PN HF as of V3.0 Shared Device" must be used for the
configuration of shared device. The remaining configuration is done in the usual way.
When configuring as a shared device, you have to insert OB 83, OB 85 and OB 122 in the block list. The transition from
STOP to RUN generates so-called "Return of submodule" alarms. The alarms are intercepted by the OB 83, otherwise the
CPU would go into STOP.
Both IO controllers that share the device must be in "RUN" in order for the IM 153-4 PN to be able to send data to the I/O.
