Modbus Plus to IEC 60870-5-104 Server Gateway

5303-MBP-104S

Limited Availability: Product with low inventory remaining. More Info

The ProLinx Modbus Plus to IEC60870-5-104 Server Gateway creates a powerful connection between devices on an IEC 104 Server network and a Modbus Plus device. This stand-alone DIN-rail mounted protocol gateway provides one Modbus Plus configurable DB9F port and one Ethernet port.

The Modbus Plus protocol driver supports both Master and Slave implementations of the protocol on the DB9 Female Modbus Plus port. The Modbus Plus port is fully configurable.

The 104S module accepts commands from an attached master unit on the network and generates unsolicited messages.

Features and Benefits

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 Data Area

This area contains module configuration information such as port configuration, network information, and command configuration. This configuration file is downloaded to, or uploaded from, this area.

Protocols

104S Protocol Specification


The 104S module accepts commands from an attached master unit on the network and generates unsolicited messages.


Protocol Specifications

Operating in the Server mode, the protocol driver can accept commands from one client at a time to read/write data stored in the module's internal registers. It supports redundant applications with two simultaneous client connections. However, it only transfers data to one of the clients at a time.

The 104S module acts as an input/output module 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
  • SNTP (Simple Network Time Protocol) timestamping for detailed logging of data transactions

 

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.
