Iec 60870-5-104 Point Lists - GE 350 Communications Manual

IEC60870-5-104 PROTOCOL

IEC 60870-5-104 point lists

NOTE:
3–34
The Single Points (M_SP) can be configured to a maximum of 64 points. The value for each
point is user-programmable and can be configured by assigning Logic Element operands.
Up to 32 Measured values (M_ME) can be configured by assigning parameters to each
Analog Input Point.
The Commands points (C_SC or C_DC) can be configured to a maximum of 16 points
selecting data from a list of Virtual Inputs and Force Coil commands.
The following Integrated Total (M_IT) will be added to the set of data:
• Total Number of Trips
The table below shows all the Configurable Points settings:
Settings
Binary Input Point 0 Entry*
Binary Input Point 63 Entry*
Analog Input Point 0 Entry*
Analog Input Point 0 Scale Factor*
Analog Input Point 0 Deadband*
Analog Input Point 31 Entry*
Analog Input Point 31 Scale Factor*
Analog Input Point 31 Deadband*
Binary Output Point 0 ON*
Binary Output Point 0 OFF*
Binary Output Point 15 ON*
Binary Output Point 15 OFF*
The settings marked "*" are the same as those used by the DNP 3.0 protocol to configure
the point mapping from address 43878 to 44101.
The IEC 60870-5-104 Deadbands settings are used to determine when to trigger
spontaneous responses containing M_ME_NB_1 analog data. Each setting represents the
threshold value for each M_ME_NB_1 analog point.
For example, to trigger spontaneous responses from the 350 when a current value
changes by 15 A, the "Analog Point xx Deadband" setting should be set to 15. Note that
these settings are the default values of the deadbands. P_ME_NB_1 (parameter of
measured value, scaled value) points can be used to change threshold values from the
default, for each individual M_ME_NB_1 analog point.
There are three ways to send the measurands to the Master station. As the measurands
will be part of the General Group and Group 2, when a general interrogation or group 2
interrogation takes place, all the measurands will be included in the response. There is also
a cyclic data period setting where the scan period is configured to send the measurands to
the Master. The final way is to send the measurands spontaneously when a deadband
overflow takes place.
Groups of Data
The data will be organized in groups in order to provide values when the controlling station
requests by general or group interrogation.
Group 1 will be set by the 64 Single Points (M_SP).
Group 2 will be set by the 32 Measured values (M_ME).
