Figure 3.14 SEL-3530 RTAC DNP3 Settings

Once a DNP port is set on the RTAC to a "Client-Multidrop Serial" a list of settings are
shown in Figure 3.14. One of these devices must be set for each remote SEL-651R on
the system. The Client DNP Address in the example is set to 1000. This is the address
of the RTAC DNP master. All devices set up on the RTAC must be set to communicate
to the same master address. Similarly on the SEL-651R all settings for REPADR
should be set to 1000.
The Server DNP Address is the address of the remote SEL-651R device. Each RTAC
device must have a unique address. The corresponding DNPADR in the SEL-651R
must be set to the same corresponding device.
The Integrity Poll and Class polling should be set such that there is enough time to poll
all remote devices in the allocated time. The more remote devices that are in a system
the longer time is needed for the polling.
The Number of Poll Retries in this example is set to 5. Given the availability of the
radio system will change this setting. If the SEL-3031 has a greater than 95 percent
availability and the ARQ in the radio is turned on then you would not expect to see
many poll retries.
The Baud Rate should be set to 38400 to match the system baud rate. The rest of the
settings are either fixed or you can leave as default.
