Introduction and Specifications
Integration Process
Use the SEL-2032 automatic message settings to program the outgoing
message and configure the SEL-2032 to collect and store the response. In the
power meter example, you can program the SEL-2032 to send the command
METER every five seconds and then store the results as numbers. Then you
can configure the SEL-2032 to configure and move the numbers so that a
master device such as an HMI can collect the data.
The SEL-2032 has eight outgoing messages that you can use to collect and
parse the response. There are also three more messages that you can use for
outgoing messages only.
Collecting data from ASCII devices is relatively easy and simple. Some
additional effort is required if the protocol is a binary protocol. See Section 7:
Settings for more information on automatic message settings (SET A) and
user-defined message settings (SET U).
The SEL-2032 does not have a Modbus
®
master setting, but you can program
the automatic message settings to emulate a Modbus master and collect data
from Modbus slave devices.
User-Defined Messages
Sometimes devices send unsolicited messages—messages not requested by
the master device. You can use the user-defined message settings in the
SEL-2032 to detect an unsolicited message and respond. The SEL-2032
cannot parse or collect data from unsolicited messages from non-SEL IEDs.
Getting More Information
If you are going to use a non-SEL device with the SEL-2032, we suggest that
you check our extensive library of application guides available on the SEL
Web site for information about various specific devices and connections. You
can also contact the factory to reach your SEL Integration Application
Engineer for local assistance with the details of your specific application.
Other SEL
Integration
Products
Several SEL products are available to help you configure, integrate,
communicate, and operate your substation. For more information on the
products listed below, please contact us or see our Web site.
Protection Networking and Expansion
Use SEL MIRRORED BITS
®
communications to connect relays and increase
protection system performance or to add remote I/O relays.
➤ SEL-2100 Logic Processor: Hub for MIRRORED BIT
communications links between protective relays. Allows high-
speed, high-security exchange and combination of logic inputs
from relays and sends results to SEL relays or SEL-2505
remote I/O modules.
➤ SEL-2505 Remote I/O Module: Remote I/O module with
eight inputs and eight outputs for SEL relays that uses
M
IRRORED BITS protocol.
