STEP 5 -
Host sends following register contents
to initiate Force Physical Input 4 Normal ( Assumed that
default password of all spaces is active).
41417 = 2020 hex (Password Hi)
41418 = 2020 hex (Password Lo)
41419 = 0
41420 = 0008 hex (Select Bit to Change)
41421 = 0000 hex ( Place Bit in Normal "Unforced" State).
41422 = 0000 hex ( Send State of Force = Don't Care)
IMPLEMENTATION TIP –As is common practice with any control, after a control task has been completed via the
network, the host should query the device to assure that control has been executed.

Group III Control Features Explained

The complimentary control functions are available for forcing the Physical Output contacts located at the back of
the relay. The Physical Output force functions follows that of the Physical Input Force Functionality. There are
three modes which a Physical Output may be placed:
• NORMAL – The TPU2000R Physical Output reflects that of the logic configured within the protective
relay
• FORCED ON – The TPU2000R Physical Output is energized. The Physical Output status is reported
as a 1. If the point status is viewed via ECP or WinECP, the point will show a forced status
•
FORCED OFF –TPU2000R Physical Output is de-energized. The Physical Output status is reported
as a 0. If the point status is viewed via ECP or WinECP, the point will show a forced status.
Table 5-45 illustrates the mapping for Physical Output Forcing Capabilities.
