Remote Terminal Unit Function - Protrol IPS2 24 VDC Manual

4.2 Remote Terminal Unit Function

The IPS2 unit includes a Remote Terminal Unite (RTU) function that can be employed to share Start and
Trip information as well as other binary and analogue objects.
Binary objects
There are nine objects for internal signals and the two binary inputs of the IPS2 unit that can be transmitted
on the RS485 System Interface (Single Point) using the IEC 60870-5-101 protocol.
