[Section]/Item Value Range Description
Time Sync Before Events: Yes or No This parameter determines if events are to be
generated by the module before the time
synchronization from the master unit. If the parameter is
set to No, no events will be generated until the module's
time has been synchronized. If the parameter is set to
Yes, events will always be generated.
Initialize DNP Database: Y or N This parameter determines if the module will request
data from the processor to initialize the DNP database
output data areas. If this option is utilized, ladder logic is
required to send the requested block from the
processor to the module.
Use Trip/Close Single Point Y or N Used for backwards compatibility with older MVI46-DNP
modules, will cause Trip/Close operations to use a
single point operation.
[Section]/Item Value Range Description
[DNP Slave Database] DNP Slave Database definition
Binary Inputs: 0 to 2048 points Number of digital input points to configure in the DNP
slave device. Each point will be stored as a single bit in
the module memory.
PLC Binary Inputs: 0 to 2048 points Number of digital input points configured above that are
to be obtained from the SLC processor. All other binary
input points must come from the attached IED units.
Analog Inputs: 0 to 256 points Number of analog input points to configure in the DNP
slave device. Each point will occupy a one word area in
the module memory.
PLC Analog Inputs: 0 to 256 points Number of analog input points configured above that
are to be obtained from the SLC processor. All other
analog input points must come from the attached IED
units.
Float Inputs: 0 to 64 points Number of floating-point input points to configure in the
DNP slave device. Each point will occupy a two-word
area in the module memory.
PLC Float Inputs: 0 to 64 points Number of floating-point input points configured above
that are to be obtained from the PLC.
Counters: 0 to 64 points Number of counter points to configure in the DNP slave
device. Each point will occupy a two word area in the
module memory. This number corresponds to the
number of frozen counters. The application maps the
counters to the frozen counters directly.
PLC Counters: 0 to 64 points Number of counter points configured above that are to
be obtained from the SLC processor. All other counter
points must come from the attached IED units.
Binary Outputs: 0 to 2000 points Number of digital output points to configure in the DNP
slave device. Each point will be stored as a single bit in
the module memory.
PLC Binary Outputs: 0 to 2000 points Number of digital output points configured above that
are to be sent to the SLC processor. All other binary
output points will be sent to the attached IED units.
