The Force Function
19–9
Forcing an External Output Circuit
A forced external output circuit is independent of the internal logic of the ladder
program and the output data file. Installing forces on output circuits af
fects only the
output force table. Installed, enabled forces do not affect the output data file or the
program logic. However, they do affect the output circuit. The effects of installed
and enabled forces can only be seen in the Run mode. The T
est mode does not
energize output circuits.
The following figure is an example online Monitor File display for processor file.
The status line indicates that the processor is in the Run mode and no forces exist.
The cursor is located on instruction O:0/0 in rung 3.

The procedure for forcing external output circuits is the same as forcing external
input data file bits. For your reference the procedure follows. Refer to pages 19–3
and 19–4 for menu displays.
