Physical Output Block (Single Bit Data) – 16 Discrete Coils (8 Elements Defined)
Output status is described in Table 5-2. The state of the addresses 00257 through 00272 follow the state of the
physical output hardware contacts located at the rear screw terminals of the relay. It should be noted that some
of the Physical Output contact status information is not available in the TPU2000R. Table 5-2 notes the elements,
which are undefined in the TPU2000R. The TPU2000R has six physical output contacts, which are map-able via
ECP software. The TPU2000R has a single dedicated physical output contact defined as TRIP. The TPU2000
has seven map-able physical output contacts (1 through 7) and a dedicated TRIP contact. The status of the
element mirrors that of the physical contact and that reported through the TPU2000/2000R front panel interface of
through the ECP or WinECP configuration program.

Logical Output Block (Two Bit Data with Momentary Change Detection)

Modbus does not support features commonly required within the utility industry. However, the protocol may easily
be adapted to support features required. It is most important that no event is to be missed by a polling host when
a device is not accessed. To this end, a feature has been developed which ensures that the status of the data
change is always reported. Table 5-3 lists the Momentary Logical Output Mapping.
