This step should be repeated for each sector used by the application. The
module will only use the sectors configured in the previous step.
Step 5: Monitor Point Configuration (Monitor Direction)
After the slave receives a Class 1 or Class 2 request from the Master, it responds
with a message containing data. Each piece of equipment is normally configured
to respond with specific points when it is being polled with a Class 2 request.
During a Class 2 response, the slave may set a control bit (ACD) to inform the
Master that there are new events to be transmitted. Then, the Master will send a
Class 1 poll to read the events from the slave.
The IEC 60870-5-103 protocol states that the data is transferred between the
Master and slave using an ASDU (Application Service Data Unit) format. Each
format is given by:
Type Identification
Variable Structure Qualifier
Cause Of Transmission
Common Address of ASDU
Function Type
Information Number
Data…
Refer to the protection equipment specification for the following information about
each point:
Type: Type of the message
Function Type: Type of protection function
Information Number: Point Identification
This information will identify each point in the MVI56-103M configuration file. The
user has to configure the points that will be updated in the MVI56-103M database
when a Class 2 or Class 1 response containing data is sent from the slave. Refer
to [IEC-103 Master Session x Sector y] section in the configuration file in order to
configure each point:
