Applications

The 104S-103M modules are the ideal solution for the many applications where IEC 104 Server connectivity can be used to integrate an IEC 103 slave device into a system. The IEC60870-5-104 Server gateway is a powerful module designed with Server support, enabling easy connection to other IEC 104 devices. In combination with the IEC 103 Master device support, the module provides a very powerful interface to the many IEC 103 slave 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.

Especificaciones

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.

103M Protocol Specification

The IEC 60870-5-103 Master driver provides extensive support for Master implementations of the protocol. The serial port on the gateway is user-configurable to support the IEC protocol (Master, Error Checking, Baud rate, etc).

The module supports:

• 16 slaves (sessions with distinct Data Link Addresses)
• Each slave (session) supports up to 3 sectors (with distinct Common ASDU Addresses)
• Configurable Time Sync and General Interrogation messages during initialization
• Supports General Interrogation, General Command and Time Synchronization Commands

104S Protocol Specification

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 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.
