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; and
