Force Current Bit
While you are editing a ladder program, you can change the force for the bit under the
cursor. The force table is transferred between the processor and computer during
uploading and downloading. Forces can be edited either online or offline. Forces do
not affect I/O until they are enabled (except for MicroLogix controllers).
To force a bit:
1. Position the cursor on an instruction with an input or output address.
2. From the top level of the ladder editor, press [F7] Force . The function keys at the
bottom of the screen change to show forcing options.
