The PACSystems* RX3i Ethernet IEC 104 Server Module, catalog number

IC695EIS001. implements the IEC 60870-5-104 communications protocol. It

permits a PACSystems RX3i controller to be connected to an Ethernet

network using a standard TCP/IP connection scheme, allowing an IEC 104

Client to poll data from the Server, as well generate unsolicited

communications from the Server back to the Client.

Two auto-sensing 10BaseT/100BaseTX RJ-45 shielded twisted-pair Ethernet

ports permit direct connection to either a 10BaseT or 100BaseTX IEEE 802.3

network without an external transceiver. Line, Star and Daisy Chain

topologies are supported.

The RX3i Ethernet IEC 104 Server Module hosts the IEC104 Server side

protocol on a common RX3i ETM001 module hardware platform. Thus, many

of the specifications and behaviors are shared with the ETM001 module

including protocol support. IC695EIS001 is an Ethernet-connected module

that fits in the RX3i backplane and permits the RX3i to behave as a Server on

the IEC104 network. The data exchanges between the EIS001 module and

IEC104 Client(s) are configurable, using a single COMMREQ instruction in the

ladder logic or Structured Text program.
