SEL-2711 Instruction Manual

ESTS
The SEL-2711 performs a number of self-tests, including RAM, Flash, EEPROM, dual-port
RAM, and Modbus Plus processor checks. If a problem is detected, it is reported to the host. See
Section 4: Operation Within SEL-2030
for information on how to access the SEL-2711 self-test
status. See
Appendix B: Error Codes and Messages
for details on the possible error conditions.

ONFIGURATION
Associated with the SEL-2711 are a number of configuration parameters. These are listed in the
following table. See
Section 4: Operation Within SEL-2030
for information on how to access
these settings using the SEL-2030.
Table 3.1: SEL-2711 Settings
Prompt
Description
ADDRESS
Prompt
: Modbus Plus node Address (1-64)
Discussion
: Select the Modbus Plus node address for the SEL-2711.
MAP_IR
Prompt
: Map Input Registers to Holding Registers (Y/N)
Discussion
: Two maps are available for the holding registers. If you select
N, the standard holding register map is used, which contains specific maps
for meter, demand meter, target, and history information. If you select Y,
the holding register accesses will access the exact same data as the input
register accesses. See
Section 4: Operation Within SEL-2030
for a
description of these maps.
PATH_
1-64
Prompt
: Control Point
1-64
routing path (Address range 1-247, 0=OFF)
Discussion
: For each outgoing control point you are using, set a Modbus
Plus node address to direct the control operation to. This must consist of a
valid Modbus Plus routing path with one to five address values separated
by periods (.). Depending on the capabilities of the host system, not all 64
of these may be available.
COIL_
1-64
Prompt
: Control Point
1-64
Modbus coil number?
Discussion
: For each outgoing control point you are using, select a coil
number to be operated. The SEL-2711 will issue ON or OFF commands to
this coil whenever it receives a set or clear command from the host device.
Depending on the capabilities of the host system, not all 64 of these may be
available).
Note
:
The actual number of PATH and COIL settings available is limited by the number of
control points supported in the host system. For instance, the SEL-2030 only has 16
available control points, so only 16 PATH and COIL settings will be available within the
SEL-2030.
