5.1.4 Port Physical and Protocol 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

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.
