6.1.4 Port Physical and Protocol Specifications
104 Server Specifications
The 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
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 104C gateway sends commands to one or more remote server units on the
Ethernet network. It also accepts monitor data sent by remote servers. Data
transferred to the server comes from the gateway’s internal database. Remote
server devices use the IEC-870-5-104 protocol to receive control outputs and
send monitor inputs using the fully-configurable gateway application database.
The remote server 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.
