Remote enable switch (SW1-1)
The PMINT provides a REMOTE ENABLE switch (see
Figure 2
)
that will enable/disable access by a PROFIBUS master to control
the opening/closing of the circuit breaker by communications . Refer
to
Table 5
.

Reserved switches (SW1-2 and SW1-3)
Switches SW1-2 and SW1-3 on the PMINT are reserved for
future use .
Section 6: PROFIBUS DP GSD file
The current GSD file for the PMINT is listed in Appendix A .
PROFIBUS DP-V0 cyclic data transfers are supported .
Section 7: PROFIBUS DP-V0 profiles
The PMINT supports the PROFIBUS DP profile for low voltage
switchgear devices (LVSG): Circuit Breaker Device Classification .
This classification provides cyclic data exchange structures for
one command (outputs from the PROFIBUS master to the PMINT
slave device) format (Format 0) and four monitoring (inputs from
the PMINT slave device to the PROFIBUS master) formats (Format
0–Format 3) . The PMINT also supports an added monitoring format
(Format 4), similar to Format 3, except the active energy value is
provided with a higher resolution .
Cyclic data exchange command structure format
Command structure Format 0 for cyclic data exchange from the
PROFIBUS master supported by the PMINT is described in
Table 6
.
The bits are defined as bit 0 is bit 0 of byte 0; bit 8 is bit 0 of byte 1 .
Cyclic data exchange monitoring structure formats
Monitoring structure Formats 0–4 for cyclic data exchange returned
from the PMINT to the PROFIBUS master are described in
Table 7
through
Table 11
, respectively .
The state information bytes are required in all monitoring formats .
The bits are defined as bit 0 is bit 0 of state byte 0; bit 8 is bit 0
of state byte 1 . The definitions are deciphered from the Primary/
Secondary/Cause-Of-Status information reported from the Trip Unit
(see
Table 13
,
Table 14
, and
Table 15
, respectively) .
The multi-byte measurement values of Formats 1–4 are transmitted
most significant byte first, as required by the PROFIBUS protocol .
