Supported Features

• Supports TCP protocol
• Supported IEC 60870-5-104 commands:
  • General interrogation
  • Specific group interrogation
  • Single point write
  • Double point write
  • Regulating step write
  • Bitstring write
  • Normalized measurand write
  • Scaled measurand write
  • Floating point measurand write
  • Clock synchronization
• Supports IEC 60870-5-104 point control mode:
  • Select/Execute
  • Select only
  • Execute only
• Support multiple slave
• Each slave can have its own IP address (IP aliasing feature)
• Each point input can be initialized by the user
• Each point can be attached to a specific interrogation group or to the cyclic group
• Event scan can be enabled for each data types to trigger spontaneous data report to the master
• Each analog point has a configurable low limit, high limit and deadband
• Configurable event scan rate
• Configurable maximum number of buffered of event for each data types
• Configurable cause of transmission (COT) size (1 or 2 octets)

Limitations

• It operates asynchronously from the model simulation step. It will try to send and receive data as fast as possible. A dedicated core can be used to improve performance.
• The event scan rate is a global parameter for the entire database. It will be the same of all types of data.
• Only TCP communication is supported.
• Each configured slave must have a unique ASDU address.
• RMS computation is only available for floating point outputs.
