IEC60870-5-104 Server to Modbus Master/Slave Communication Module
5201/5202-104S-MCM(4)
Product Description
The ProLinx family IEC60870-5-104 Server to Modbus Master/Slave communications module (5201-104S-MCM) creates a powerful connection between devices on a Modbus network and an IEC 104 client device. The module is a stand-alone DIN-rail mounted protocol gateway that provides one Ethernet port and up to four serial ports.
The 104S module accepts commands from an attached master unit on the network and generates unsolicited messages.
The Modbus (MCM) protocol driver supports Master and Slave implementations of the protocol. All Modbus serial ports are individually configurable, providing a very powerful and flexible host or device interface solution.
Product Applications
The 104S-MCM modules are the ideal solution for the many applications where Modbus connectivity can be used to integrate an IEC 104 slave device into a system.
The Modbus gateway is a powerful module designed with both Master and Slave support, enabling easy connection to other Modbus devices (Modicon processors and many others). In combination with the IEC60870-5-104 Server device support, the module provides a very powerful interface to the many IEC 104 client devices which are in use in the industrial marketplace today. Applications for the module are found in most industries, especially the Manufacturing, Oil and Gas, Electrical Power and Food Processing.
Functional Specifications
Internal Database
The ProLinx module contains an internal database that consists of areas for application data, status information, and configuration information.
The internal database is shared between all ports on the module and is used as a conduit to pass information from a device on one network to one or more devices on another network.
Application Data Area
The data area is used to store and retrieve data by the protocol drivers and for data exchange between protocols. The database is used as a source for write commands to remote devices and holds data collected from the remote devices. Commands defined in the configuration file (stored in the configuration data area) control how the data is to be handled in the database.
Status Data Area
This area is used to store error codes, counters, and port status information for each port.
Configuration File
This file contains module configuration information such as port configuration, network information, and command configuration. This configuration file is downloaded to, or uploaded from, the module.
IEC 60870-5-104 Server Protocol Specifications
Operating in the Server mode, the protocol driver accepts commands from one or more clients to read/write data stored in the module's internal registers.
The 104S module acts as a gateway between the IEC 60870-5-104 Ethernet network and many of the other serial and network protocols, as well as several proprietary interfaces.
General specifications include:
- User-definable module memory usage
- Protocol implementation conforms to the IEC 60870-5-104 specification with fully configurable parameters
The 104S module accepts commands from an attached master unit on the network and generates unsolicited messages. These last sets of messages are either spontaneous or cyclic. Data transferred to the host is derived from the module's internal database. The remote master device can control data in the database and hence the devices connected using the other protocol in the module using standard control messages supported in the protocol. The remote master device uses the fully-configured databases in the module to control outputs and monitor inputs.

Modbus Protocol Specifications
The Modbus driver provides access to an internal database of 4000 registers (words), with extensive support provided for both the Master and the Slave implementations of the protocol. The serial port(s) on the gateway can be individually configured to support the Modbus protocol (Master or Slave, RTU or ASCII, Baud Rate, etc).
