Guide to Forcing External Input Data File Bits
The following occurs in the Run or Test mode:
•
The ladder program is scanned and ladder logic is applied.
•
True instructions are intensified in the display.
•
Forcing of input data file bits and resultant data changes appear in the data file
displays.
The table below shows the available function keys and describes how each of them
functions.
Function Key Description
[F1] OFF
Enters a 0 in the input force table for the highlighted external
input bit address. This installs a force.
[F2] ON
Enters a 1 in the input force table for the highlighted external
input bit address. This installs a force.
[F3] Remove
Affects the highlighted external input bit address. It removes
the installed force from the force table and the data file, if
applicable. Other forces are unaffected.
[F4] Remove All
Affects all forced external input bit addresses and external
output circuits. It removes the installed forces from the
external bit addresses and output circuits. You must confirm
this selection.
[F7] Enable
(Does not apply to MicroLogix 1000 controllers.)
Enables all forces, both inputs and outputs. You must confirm
this selection. Note, the processor must be in the Run or Test
mode to see the effects of the forced input table.
[F8] Disable
(Does not apply to MicroLogix 1000 controllers.)
Disables all forces, both inputs and outputs. You must confirm
this selection. Note, the processor must be in the Run or Test
mode to see the effects of the forced input table.
