Displaying Information About Bus Devices
Select F3 (Block/Bus Status) from the Analyze
menu to:
H Display the references assigned to any device.
H Display the revision level of any device.
H Display the description and Global Data ad-
dress of a bus controller.
H Display the fault status of a Genius block or
Remote I/O Scanner (remote drop).
H Select the active device.
H Clear all faults on the active device.
H Access the Bus Status display.
This screen provides a quick way to check for faults
and forced circuits before starting up a system.
Block/Bus Status Displays for Bus Devices
Example displays are shown below. (Display format
for bus controllers is shown on the next page).

Line 1 shows the I/O references used by the device.
If * symbols appear instead of references, the
device’s references are incorrect for the type of host
CPU currently set up for the HHM. For example, if
a device is assigned to Series Six registers, and the
HHM is set up for a Series 90 host, the HHM will
display * symbols instead of references.
Line 1 also provides information about the device
currently being displayed:
I = Input block
O = Output block
O
I
= Block with both inputs and outputs
A = Analog, RTD or Thermocouple block
G = PowerTRAC block or Remote I/O Scanner
Line 2 identifies the device and shows its serial bus
address (also called its Device Number or block
number), and its revision level.
Line 3 shows whether the device presently has
any forces or faults. If the device is a Field Control
BIU or Field Processor, however, the presence of
faults is not indicated on this screen.
Selecting Another Device
Press F1 (Next) or F2 (Previous) as needed to
display information about other device.
Note: Poor bus conditions may cause the HHM to
skip (not display) a device that is present on the
bus. Try moving the HHM to a different
connector on the bus. Occasionally, this problem is
caused by certain older Genius blocks that do not
communicate with the HHM properly. If the
problem persists, such blocks can be upgraded.
Selecting the Active Device
Initially, the active device is the one to which the
HHM is connected.
You can display information about other devices
without making them “active”.
However, for many functions the HHM must be
attached to another device or the other device must
be made “active” by following the steps below.
1. From the Analyze menu, select F3 (Block/Bus
Status).
2. Press F1 (Next) or F2 (Previous), to reach the
device’s description screen.
3. When the device’s screen appears, press F3
(Active) to make it the active device. (On a
dual bus, the HHM must be on the same bus as
the active block. If it is not, either move the
HHM or force the bus selection)
4. Press D MENU to return to the Analyze menu.
