IED Binary Input Data
This data area stores binary input data retrieved from IED units attached to the
DNP master port. The size of the data area is determined by the configuration
parameter Number of Binary Input Points for IED. The command list polls IED
units for their binary input data and to place the data in the database. The SLC
program uses this input data for monitoring and control in the ladder logic
program. The module transfers these data to the M1: file elements 768 to 895.
This provides for 2048 binary input points.
IED Binary Output Data
This data area controls IED units attached to the DNP master port. The size of
the data area is determined by the configuration parameter Number of Binary
Output Points for IED. The command list sends the control values in this
database to the IED units. The SLC ladder logic program is responsible for
setting the values in this database. This provides direct control of IED units by
the SLC program. These data are stored in the module M1: file elements 1280 to
1407. This provides for 2000 binary output points.
IED Counter Data
This data area stores counter and frozen counter data retrieved from IED units
attached to the DNP master port. The size of the data area is determined by the
configuration parameter Number of Counter Points for IED. The command list
polls the IED units for their counter or frozen counter data. The SLC program
uses this data for monitoring or control in the ladder logic program. The module
transfers these data to the M1: file elements 1152 to 1279. This provides for 64
counter points.
IED Analog Input Data
This data area stores the analog input data retrieved from IED units attached to
the DNP master port. The size of the data area is determined by the
configuration parameter Number of Analog Input Points for IED. The command
list polls the IED units for their analog input data. The SLC program uses this
input data for monitoring and control in the ladder logic program. The module
transfers these data to the M1: file elements 896 to 1151. This provides for 256
analog input points.
IED Analog Output Data
This data area controls IED units attached to the DNP master port. The size of
the data area is determined by the configuration parameter Number of Analog
Output Points for IED. The command list sends the control values in this
database to the IED units. The SLC ladder logic program is responsible for
setting the values in this database. This provides direct control of IED units by
the SLC program. These data are transferred to the module M1: file elements
1408 to 1535. This provides for 128 analog output points.
