Discrete 4X Register Bit Data Reporting (26 Registers Defined)

The TPU2000 and TPU2000R offers bit status reporting via 0X and 1X Modbus/Modbus Plus command retrieval.
Some hosts however do not offer the capability to read data via these data types. The data types have been
structured to be reported in 4X data types. Reported data is of the following types:
Logical Outputs
Logical Inputs
Physical Inputs
Forced Physical Input State Reporting
Forced Physical Output State Reporting
Forced Logical Input State Reporting
The following registers only report the status of the elements. Some of the elements are latched and behave as
do their 0X and 1X counterparts. The bits are reset depending upon the reset control via the 4X control registers
(Reference Section 5).
It should be noted that for the following bits, the operational characteristics are included for reference:
TCFA – Trip Circuit Failure Alarm – This bit indicates that the Trip Circuit is Open.
continuously energized (value = 1) until circuit continuity is sensed.
TFA – Trip Failure Alarm – This bit indicates that a fault has not been cleared within the programmable Trip
Failure Time setting of 5 to 60 Cycles. Use the Trip Failure Mode Setting (Differential, Overcurrent, or Differential
and Overcurrent) to select the type of faults for which a trip failure alarm will be given. The Trip Failure Alarm
clears when the current drops below the Trip Failure Drop-Off setting.
PUA - Pick Up Alarm: Differential and Overcurrent (87/51/50/150/46) Pickup Alarm. Indicates that an enabled
protective function is picked up and can be used as a fault detector alarm. The Alarm Resets 500 mS after the
"picked up" state has dropped out.
