The 350 relay is identified in this protocol as "overcurrent protection", so it will use the
Function Type <160> for all the digital and analogues points proposed by the standard and
mapped in this profile. For the other data supported by the device, the customer will have
the capability to use them by setting a number from the private range.

The 350 relay supports a fixed profile and data that is configurable using the EnerVista SR3
Setup program.
The data that can be configured are:
• digital states
• measurands
• commands.
Digital states in the relay may be mapped using the EnerVista SR3 Setup program. By
default, states are mapped to information numbers proposed by the standard, but the
user may delete these mappings if desired.
All the mapped information will be sent as a response to a general interrogation like ASDU
1.
For the other states, the customer can assign:
1. Information Number <1..255>
2. Function Type <0..255>.
