Block/Bus Status Display for a Bus Controller
If the active device is a bus controller, the Block/Bus
Status display shows information appropriate to that
bus controller type. For example:

Switching a Dual Bus
To force a bus switch in a redundant bus system,
the HHM must be connected to the same bus as
the presently-active device.

1. If necessary, make the BSM Controller the ac-
tive device.
A. From the Analyze menu, select F3 (Block/
Bus Status).
B. Press F1 (Next) or F2 (Previous), to reach the
status screen for the BSM Controller.
C. When it appears, press F3 (Active) to make
the BSM Controller the active device.
2. Press
