SCADA Protocol
The communications gateway supports the use of the DNP3 protocol by default. It also
supports the IEC 60870-5-104 protocol, or the “IEC104” protocol, which is a separate com-
munications protocol from the DNP3 protocol. To switch to the IEC104 protocol, click
on the IEC104 Enable toggle button, and then click on the Save button. See Figure 19.

Note: Instructions for configuring the communications gateway using the IEC
60870-5-104, or “IEC104,” protocol are contained in S&C Instruction Sheet 461-519,
“TripSaver® II Cutout-Mounted Recloser: Communications via Gateway using the
IEC104 Protocol: Installation, Operation, and Configuration.”
Note: When enabling or disabling the IEC104 protocol, if settings have already been
made with the communications gateway set to the DNP3 protocol, those settings will
not be lost when the user enables IEC104, and vice versa.
