This protocol (known also as IEC 870-5-104 or IEC-104) implements a server side of IEC-104 communication.
Communication supports reading and writing data by means of the IEC870IEC 60870-5-104 communication protocol operating on the basis of TCP network communication. D2000 system works in the mode IEC 87060870-5-104 server (slave), that is enable to communicate with multiple (N) clients (masters). Implementation is according to the standard IEC870IEC 60870-5-104 as follows:
- initial Originator ASDU address is 1 byte, it is defined as line number.
- ASDU address is 2 bytes, it is defined as station address. For each station on one line, there must be defined different ASDU address.
- Cause of transmission is 2 bytes (it also contains Originator ASDU address)
- Information object address = 3 bytes, it is defined as I/O tag address.
- There are implemented the following ASDU types in the direction of logging (from D2000 system to control station and also vice-versa in balanced mode):
