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:

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

% R1

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)).

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.
