Chapter 5 Monitoring the Bus and its Devices
Clearing Faults from the Block/Bus Status Screen
Pressing the CLEAR key from this screen clears all
faults on the active device. For Genius blocks, if
you want to clear a specific circuit fault, select F2
(Monitor/Control Reference) from the Analyze
menu instead.
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:
S E R I E S 6
B U S A D R : (device #)(vers)
R E G (registers)
n x t p r v r / g b u s
The first line identifies the bus controller type. If it
is a Series Five bus controller, PCIM, or QBIM, the
first line indicates:
G E N I
The second line of the display shows the bus
controller’s Device Number followed by its
firmware revision level.
Reading a Global Data Address
The third line of a bus controller’s Block/Bus Status
screen shows its assigned Global Data address.
If no Global Data address appears, it means that
either:
H The bus controller has no Global Data address.
H A Series 90-70 bus controller has a Global Data
address in %I, %Q, %AI, %AQ, or %R memory,
and no optional Series Six register address was
configured for the bus controller.
If a Global Data address has been set up, you can
use the F3 (R/G) key to toggle between (R)egister
and (G)lobal memory format. If no Global Data
reference has been set up, the F3 key is not assigned.
Monitoring the Bus Status
To display the number of devices currently operating
on the bus, and the current bus scan time, select F4
(Bus) from the Block/Bus Status display.
S C A N T I M E 1 O m s
S E R I A L B U S S T A T S
A C T V D E V I C E S = 7
The bus scan time shown is rounded down to the
nearest millisecond (10mS represents 10.01 to
10.99mS).
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 D MENU to return to the Analyze menu.
3. From the Analyze menu, select F2 (Monitor/
Control Reference). The HHM shows the ac-
tive bus and whether it is forced. For example:
M N T R / C T R L (input ref)
S T A T E : B U S B F R C
> b u s A b i s B r e l s
4. Press F2 or F3 to select the other bus. The LED
on the BSM is off when bus A is selected and
on when bus B is selected. The I/O Enabled
LED on each block on the active bus blinks.
