. There are three modes which a Physical Output may be placed:
• UNFORCED – The TPU2000/TPU2000R Logical Input is not forced to any state.
•
FORCED ON – The TPU2000/TPU2000R Logical Input is energized and associated mapped function
is enabled. The Logical Input status is reported as a 1. If the point status is viewed via ECP or
WinECP, the Logical point will show a forced status with a logical state of 1.
•
FORCED OFF – The TPU2000/TPU2000R Logical Input is de-energized. The Logical Input status is
reported as a 0. If the point status is viewed via ECP or WinECP, the point will show a forced status
with a logical state of 0.
