5.1.4 IEC-870-5-104 Protocol Implementation Specifications
104 Server Specifications
The 104S gateway acts as a link between the IEC-870-5-104, other protocols and
networks, as well as several proprietary interfaces. A 4000-word register space in
the gateway exchanges data between the two protocols.
General specifications include:
Supports storage and transfer of up to 4000 registers between protocols
User-definable gateway memory usage
IEC time used by the gateway can be stored in the memory database
Configures via a user-generated text file download to the gateway
Protocol implementation conforms to the IEC-870-5-104 specification with fully
configurable parameters
Event Priority Queues available
Invalid Bit Monitoring available
Supports Redundant Connections
Driver Protocol Specifications
General Parameters
Internal Database
4000 registers (words) available
Communication parameters
10Base-T half duplex RJ45 Connector
Link and Activity LED indicators
Status Data
Status data is returned in a block of counter values allowing
communications to be effectively debugged.
Conformance Specifications
See IEC 60870-5-104 Server Interoperability Document
(page 130)
Server Functional Specifications
The 104S gateway accepts commands from one or more remote Client units on the
Ethernet network and generates unsolicited messages to the Clients. Unsolicited
messages can be sent based on data change events or on a timed cycle. Data
transferred to the Client comes from the gateway’s internal database. Remote Client
devices use the IEC-870-5-104 protocol to control outputs and monitor inputs using
the fully-configurable gateway application database. The remote Client devices can
overwrite data in the database and, thereby, pass control data to devices connected
to the gateway using standard control messages supported by the other gateway
protocol.
