1. Click in the Class field of the signal. A new window Select Class opens where the
user classifies the signal.
2. Select the signal classes and choose between None and 0 to 3 according to the
project demands.
3. Click OK to set the signal classification.
4. Write to IED.
Selecting to communicate DNP3 data via RS485 serial
interface on COM03 or COM05 module
1. In PST, navigate to the RS485PROT function block located in MainMenu/
IEDConfiguration/Monitoring/RS485PROT:1.
2. To enable the DNP3 protocol on the RS485 port, select DNP for setting
Operation.
3. Navigate to the MSTSERIAL function block, located in MainMenu/
IEDConfiguration/Communication/DNP3.0/MSTSERIAL:1 and set
ChToAssociate to RS485.
See DNP3 Communication protocol manual, chapter DNP3
parameters, for more detailed information.

RS485 specific parameters

There are a few parameters that are specific to RS485 and are separated from the
protocols. This makes it possible to run RS485 hardware without defining any
protocols. This enables the IED to operate correctly in a ring topology even if no
protocols are configured to run.
Selecting to communicate DNP3 data via optical serial
interface on COM03 or COM05 module
1. In PST, navigate to the OPTICALPROT function block located in MainMenu/
IEDConfiguration/Monitoring/OPTICALPROT:1.
2. To enable the DNP3 protocol on optical serial port, select DNP for setting
Operation.
3. Navigate to the MSTSERIAL function block, located in MainMenu/
IEDConfiguration/Communication/DNP3.0/MSTSERIAL:1, and set
ChToAssociate to Optical.
