IEC60870-5-103 Protocol Configuration
In order to use the IEC60870-5-103 protocol it has to be assigned to the X103 Interface within the Device
Planning. The device will reboot after setting this parameter.
The parameter X103 is only available if the device is at the rear side
equipped with an interface like RS485 or Fiber Optic.
If the device is equipped with an Fiber Optic Interface, the Optical Rest
Position has to be set within the Device Parameters .
The time-controlled IEC60870-5-103 protocol is based on the Master-Slave working principle. This means that
the substation control and protection system sends an enquiry or instruction to a certain device (slave address)
which will then be answered or carried out accordingly.
The device meets the compatibility mode 2. Compatibility mode 3 is not supported.
The following IEC60870-5-103-functions will be supported:
•
Initialization (Reset)
•
Time Synchronization
•
Reading out of time stamped, instantaneous signals
•
General Queries
•
Cyclic Signals
•
General Commands
•
Transmission of Disturbance Data
Initialization
The communication has to be reset by a Reset Command each time that the device is turned on or that
communication parameters have been changed. The “Reset CU” Command resets. The relay acts on both
Reset Commands (Reset CU or Reset FCB).
The relay acts on the reset command by an identification signal ASDU 5 (Application Service Data Unit), as a
reason (Cause Of Transmission, COT) for the transmission of the answer either a “Reset CU” or a “Reset FCB”
will be sent depending on the type of the reset command. This information can be part of the data section of the
ASDU-signal.
Name of the Manufacturer
The section for the identification of the software contains three digits of the device code for the identification of
the device type. Beside the upper mentioned identification number the device generates a communication start
event.
Time Synchronization
Time and date of the relay can be set by means of the time synchronization function of the IEC60870-5-103
protocol. If the time synchronization signal is send out with a confirmation request, the device will answer with a
confirmation signal.
