2.1
Routing of frames of the slave initiative
The IM 153-2BAx2 support routing of frames of the slave initiative. In so doing, the frames of
devices are passed behind the link to the higher-level controller.
This routing can be used, for example, to operate SINAMICS drives behind the Y Link if the
trace function is being used with the STARTER commissioning tool.
2.2
Improved link behavior during commissioning
Starting situation
The IM 153-2BAx2 interface modules are installed in one link and should be operated
redundantly in an H System (e.g., SIMATIC S7-400H).
Behavior of IM 153-2BAx2
If the IM 153-2BAx2 detects a redundancy partner that is not ready to be switched to or if
there are no lower-level slaves, the interface module stops sending continuous diagnostic
messages.
This behavior can also be implemented for the following interface modules by means of a
firmware update:
●
IM 157 (6ES7157-0AA82-0XA0)
●
IM 153-2 (6ES7153-2BAx1-0XB0)
This "new" behavior of the IM 153-2BAx2 is not available for redundancy mode in
accordance with the standard.
