Chapter 5 Monitoring the Bus and its Devices
Monitoring/Controlling Remote Drop Data
The HHM can display diagnostics and current I/O
states, and force and unforce individual I/O points
on I/O modules in a remote drop.
When the active device is a Remote I/O Scanner,
the HHM’s Monitor Block and Monitor/Control
Reference functions display the same set of
screens. This is unlike HHM operation for Genius
blocks, where the screens for Monitor Block and
Monitor/Control Reference are different.
For the Remote I/O Scanner, the monitoring
screens provide the following information:
1. The states of the discrete inputs in the remote
drop, in ascending order.
2. The values of the analog inputs in the remote
drop, in ascending order.
3. The states of the discrete outputs for the re-
mote drop, in ascending order.
4. The values of the analog outputs for the re-
mote drop, in ascending order.
On each screen, line 3 shows the state or value of
one circuit at a time. It also indicates whether the
circuit is forced, or has a fault as illustrated below.
The first screen that appears is the Monitor screen
for the module with the first %I reference.
M N T R 1
1 4 3 # O . 2 % I 1
S T S O F A U L T
> r e f f o r c e d i a g
Line 1 shows the relative number in the word of
the circuit being monitored:
M N T R 1
Here, it is the first circuit on the block. The second
line identifies the I/O module being monitored:
1 4 3 # 4 . 2 % I 1
It shows the Remote Drop ID (143 in this
example), the rack number (0),the slot number (2),
and the memory type (%I). The number on the
righthand side of the second line represents a data
word.
1 4 3 # 4 . 2 % I 1

Reference Type
The Series 90-70 I/O reference for the circuit is one
less than the sum of the two numbers on the
righthand side of the HHM screen. For example:
M N T R 3
1 4 3 # 4 . 3 % I 3 3
3 + 33 – 1=35
In this example, the circuit being monitored is
%I0035.
Displaying Other Circuits
To display additional circuits, press the F1 ( > ) key.
The HHM will step through each available circuit.
To jump directly to a particular device, memory
type, or address, press F2 (ref). This screen
appears, to enter the desired information.
M N T R 3
t g l c h n g e n t r
1. Enter the reference number. Press F3 (entr).
The memory type blinks on the screen.
2. If you want to select a different reference type
(for example, to display%AQ instead of %I),
press F2 (chng) to toggle the memory type.
3. With the desired information displayed, press
F3 (entr) to monitor the circuit.
