7. Scaling and Display Settings
The VOLT_SCA, POWR_SCA, ENRG_SCA, and PRI_SCA configuration settings affect how the meter
reports quantities to communications channels and internal and external interfaces. The meter always
reports LDP1 energy values as change-over-internal (COI) in primary kilo units to ensure compatibility
with MV-90 software. All other LDP recorders report energy as defined by the scaling settings.
8. Communications and Protocol Settings
The SEL-735 supports the communications protocols listed in Table 2 . The Ethernet port supports six
simultaneous communications sessions, including five DNP3 LAN/WAN sessions. Port 4 supports three
communications options, but only one is available at a time.
To change the communications parameters, click on the desired communications port followed by

A. Device Overview
The Device Overview window emulates the
front-panel interface of the SEL-735 and
updates approximately every second. This
window displays instantaneous metering
information, and contact I/O and front-panel
LED status.
