Configuring the D25 to work with a DNP3 I/O Module
Introduction Your D25 RTU Master communicates with your DNP3 I/O modules through
the DNP3 Data Collection Application (DCA B023). The DNP DCA collects
data from, and sends control requests to, the DNP3 I/O modules.
Refer to
0 Appendix D: Installing and Connecting DNP3 I/O Modules for
installation and connection instructions.
Use SGConfig to configure the DNP3 DCA in the D25 so that it
communicates with your DNP3 I/O module. There are three tables to
configure:
• Remote Device Table: This table contains one record for each DNP
I/O module in the system. The Remote Device Table specifies the
remote devices with which the DCA communicates, the polling
parameters for each remote device, and the points configured on each
remote device. Each record in the Remote Device Table references the
appropriate Remote Device Point Mapping Table(s) and Remote
Device Polling Table(s).
• Remote Device Point Mapping Table: Specifies the number and type
of data points associated with each DNP I/O module.
• Remote Device Polling Table: Specifies the polling type and frequency
for each DNP I/O module.
Instructions and guidelines for configuring your DNP3 DCA can be found in
the following documentation:
•
DNP V3.00 DCA - Configuration Guide
(B023-0CG)
• SGConfig online help.
Note : When configuring the Time Sync option:
• Disable Time Sync for the D20A and D20K modules
• If Time Sync is enabled on a D20S module, the polling rate may be a
minimum of 2 seconds (it takes about 850ms to do a Time Sync for each
device).
