Hand-held Monitor User’s Guide – June 1994
Series 90 PLC
For a Series 90-70 PLC, the Hand-held Monitor can
read data from %R, %AI, %AQ,%I, %Q, %T, %M,
%S, %SA, %SB, %SC, and %G memory.
For a Series 90-70 PLC, the memory
location/content screen looks like this example:
D E V I C E M E M O R Y 1 5
% R 1
t g l c h n g e n t r S B A
The top line shows the currently-selected Device
Number (15 in the example above). Line 2 shows
the memory type currently accessed, and a
reference location within that memory type. In
this example, the selected location is %R0001.
From this screen, use the HHM function keys to:
A. Select a different bus device (press F4 (SBA)).
B. Select another memory type (press F1 (tgl)).
C. Select another reference location (press
F2(chng), then enter the desired numerical
offset).
D. Display the current memory contents of the
specified location (press F3 (entr)).
When F3 (entr) is pressed, the HHM displays the
content in either bit or word format, as
appropriate for the selected memory type. For
example, here word data is displayed, because the
selected memory type (%R) is word-based:
D E V I C E M E M O R Y 1 5
% R 1
W O R D 1 3 9
> < l o c
From this screen, you can display the current
contents of other locations in the selected memory
type:
A. Use the F1 ( > ) key to increment the memory
offset (location).
B. Use the F2 ( < ) key to decrement the memory
offset.
C. Use the F3 (loc) key if you want to enter an off-
set from the HHM keypad.
