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.
