Emerson PACSystems RX3i Ethernet IEC 104 Server Module IC695EIS001

Introduction

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-Jx 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

• Supports eight client connection to the RX3i Controller data set specified in the configuration. [RBE supported only

on one Client connection associated with a specified port -Refer to GFK-2949B for details]

• 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.

• Supports 56-bit IEC 60870-5-104 time format, with the default being 56-bit time format.

• Supports Time Set, and query of the RX3i Controller CPU Clock in UTC time.

• Cause of Transmission size is two octets.

RX3i Interface specifications:

• Up to four EIS001 per RX3i, as allowed by available power and slots.

• Module can be installed in any available RX3i main rack I/O slot.

• Module supports insertion into and removal from an RX3i backplane which is under power.

• Firmware upgrade through RX3i CPU using WinLoader software utility.
