IEC 60870-5-104 Server Specifications
Operating in the Server mode, the module accepts commands from a Client(s) to
read/write data stored in the module’s internal registers. This data is easily and
continuously transferred between the ProTalk module and the Quantum
processor’s data registers.
The IEC 60870-5-104 Server functionality supported by the module includes:
 The IEC 60870-5-104 communication driver is built in accordance to the
approved IEC specification
 The module functions as a Server on the network supporting data read/write
commands from an IEC 60870-5-104 client on the network
 One TCP server socket
 Supports unsolicited messages, either cyclic or spontaneous (cyclic rate is
configurable)
 Supports clock synchronization commands from client or from the Quantum
 Supports Group interrogation (Global, General 1 to 16, Global Counters,
Counters 1 to 4)
 Event time-stamping configurable by type (None, 24 bit, 56 bit)
 Event queue supports 99 points for each data type
 Optional user defined list of acceptable client host IP addresses
 Configurable Common ASDU address (sector) and Information Object
Address
 An IEC Interoperability Document for the ProTalk is available which fully
documents data types supported by the module
