X8705ILS: ALSTOM ILSA Interface IEC 60870-5-103 Protocol Driver v10.0

X8705ILS: ALSTOM ILSA Interface IEC 60870-5-103 Protocol Driver

General Information:

The X8705ILS driver was developed to communicate with Areva Alstom protections that use the ILSA interface.

The ILSA interface conforms to the internationaI IEC 60870-5-103 standard.

This driver uses the unbalanced transmission procedure, as it is normally used in SCADA systems in which a master station controls the data traffic by polling outstations sequentially.

The master station is the primary station that initiates all message transfers while secondary stations (slaves) may transmit only when they are polled.

IEC 60870-5-103 protocol standard admits exclusive frame format FT 1.2 defined in IEC 60870-5-1 (Transmission frame formats). Formats with fixed and variable block length are admitted. Also the single control characters E5H are used. The transmission of data bytes takes place after the principle "LSB first". This is an asynchronous protocol with hamming distance = 4. The sequence of user data characters is terminated by a 8 bits checksum. The checksum is the arithmetic sum over all user data octets.

Frame with variable length is used for data transmission of user data between controlling and controlled station.

Link address field is fixed with 1-byte length.

Originator address field is not included in telegrams.

Common address of ASDU is fixed with 1-byte length.

Information object address field is fixed with 2-byte length.

This driver supports RS485 networking to connect multiple slave devices to a single computer.

This driver supports direct communication to a serial port.

Also supports tcp/ip communication through an ethernet-to-serial converter such as Moxa or Exemys, without needing to install a COM port redirector or creating a virtual COM port.

The licenses of all our drivers are unlimited in terms of the number of machines where they can be used, the number of I/O that can read or written, and the number of components that can be included in each application.

After purchasing a license, the owner can use the driver and all its components to assemble and distribute as many applications to as many users as needed.

The license owner retains full control of his applications by deciding himself what target machines can they be run at. For this, each driver is provided with two runtime license management tools: GetPCId.exe and MakeLic.exe.
