General Specifications – 104S
Operating in server mode (only), the 104S protocol implementation accepts commands from an IEC-60870-5-104 Client to read data stored in or write data into the gateway’s internal database memory registers. The 104S implementation is also capable of generating unsolicited messages. Unsolicited messages can be either spontaneous (event-driven) or cyclic (timing-driven) communication.
The remote Client device uses the fully-configurable gateway memory database to control outputs and monitor inputs to devices on the IEC 104 network. Changes to the gateway database can also be used to transfer monitoring and control data to devices connected to the gateway using another installed network protocol. The 104S gateway thus provides a data transfer solution between an IEC 60870-5-104 Ethernet network and other serial and Ethernet network protocols, as well as proprietary interfaces.
General specifications include:
 User-definable database memory usage, based on data types and point counts
 Protocol implementation conforms to the IEC 60870-5-104 specification with fully-configurable parameters
 SNTP (Simple Network Time Protocol) timestamping for detailed logging of data transactions (events)
