Description

The RX3i IEC 104 Server Module, catalog number IC695EIS001 (or EIS001), hosts the IEC
104 Server protocol on a common RX3i ETM001 module hardware platform. Thus, many of
the specifications and behaviors are shared with the ETM001 module. IC695EIS001 is an
Ethernet-connected module which fits in the RX3i backplane and permits the RX3i to
behave as a Server on the IEC 104 network.
The data exchanges between the EIS001 module and one IEC 104 Client are configurable,
using a single COMMREQ instruction in the ladder logic or Structured Text program, as
detailed in 0, and are limited to exchanging only linear (%) memory. Symbolic references,
which represent non-linear use of memory, cannot therefore be specified in this interface.
However, the corresponding data may be exchanged as part of a block of memory (%R, for
instance).

Product Overview

The PACSystems RX3i Ethernet IEC 60870-5-104 Server Module, catalog number
IC695EIS001 implements the IEC 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.
Module Features
The Ethernet 104 Server Module:
• Supports up to eight connections to the RX3i Controller data set specified in the
configuration.
• Supports Interrogation and RBE for Single Point and Double Point data.
• Supports Interrogation and RBE for Regulated Step.
• Supports Interrogation and Measured data sets for Scaled, normalized, and single
precision Float.
