Guide to Forcing External Output Circuits
The following occurs in the Run mode:
•
The ladder program is scanned and ladder logic is applied.
•
True instructions are intensified in the display.
•
Controller output LEDs go on and/or are held on for enabled forced on external
output circuits.
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 output force table for the highlighted
instruction. This installs a force. If the force is enabled and the
processor is in the Run mode, the force is applied and the
output circuit remains forced until the force is removed. The
data file bit is unaffected.
[F2] ON
Enters a 1 in the output force table for the highlighted
instruction. This installs a force. If the force is enabled and the
processor is in the Run mode, the force is applied and the
output circuit remains forced until the force is removed. The
data file bit is unaffected.
[F3] Remove
Affects the highlighted external output circuit. It removes the
installed force from the force table. 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 mode
to see the effects of the forced output circuits.
[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 mode
to see the effects of the forced output circuits.
