Example 6: Modbus Job Done
Accessing
Centralized Data
This example demonstrates the ability of the SEL-2032 to centralize data to
reduce the number of Modbus accesses necessary to collect data. This
example uses an SEL-121F and an SEL-501 on Ports 3 and 4 of an SEL-2032,
respectively. The objective is to read the current and voltage magnitudes from
the relays with a single Modbus access. Optional steps are shown to
automatically move the data to a region accessible to a Modbus master that
cannot use 6-digit addressing. The following procedure explains how to set the
SEL-2032 and collect the data.
Step 1. Connect the two relays to Ports 3 and 4 of the SEL-2032.
Establish basic communications settings to the first relay by
auto-configuring using
SET P 3
. Use
SET A 3
to set meter data
collection. Copy these settings to Port 4 using
COPY 3 4
.
Auto-configure Port 4 while copying.
Step 2. Set Port 16 to be a Modbus port, as shown in
Table 3.12
