Hand-held Monitor User’s Guide – June 1994
Series Five PLC
For a Series Five PLC, the Hand-held Monitor can
read data from register memory. That includes I/O
data mapped into register memory, (it is easier to
display I/O data with the HHM’s Monitor Block or
Monitor Control Reference function).
For a Series Five PLC, the Device Memory screen
looks like this example:
D E V I C E M E M O R Y 7
M E M : (location)
t g l c h n g e n t r S B A
The top line shows the currently-selected Device
Number (7 in the example above). If there is a
currently-selected memory location, it appears on
the second line of the display as two numbers
separated by a colon.
The number on the left will be:
133 for a Series Five PLC
The number on the right is the actual memory
location that will be read.
From this screen, use the Hand-held Monitor
function keys to:
A. Select a different device on the bus (press F4
(SBA)).
B. Select another memory type (press F2 (chng)).
See right for instructions.
C. Select another reference location in the dis-
played memory type (press F2(chng)). See
right for instructions.
D. Display the current memory contents of the
specified location (press F3 (entr)).
Enter or Change the PLC Type
To enter or change the PLC type:
1. Press F3 (chng). A cursor appears at the left of
the colon. For a Series Six PLC, enter the num-
ber 32768.
2. Press the F3 (entr) key.
Enter or Change the Memory Location
To enter or change the memory location:
1. On the same screen, press F1 ( > ) to move the
cursor to the right of the colon.
2. Press F2 (chng).
3. Enter the byte offset of the data. This is equal
to (2 x register #) – 2. For example, for regis-
ter#100, you would enter (2 x 100) – 2, which
is 198.
I/O Data
Series Five I/O data can be displayed using the
integer result of this formula:
(point number) / 8 + table offset
The table offsets for Series Five I/O are:
channel 1 inputs 32768
channel 2 inputs 32896
channel 1 outputs 33024
channel 2 outputs 33152
Example: to display channel 2 output 12, you
would enter:12/8 + 33152, which is 33153:
M E M : 1 3 3 : 3 3 1 5 3
Press F3 (ENTR) to save the memory location. To
display the memory content of this location, press
F3 (ENTR) again.
