ProTester IEC-103 Master 1.1

ProTester IEC-103 Master by Info Tech is a professional testing and simulation tool that operates as an IEC 60870-5-103 master for commissioning, diagnosing, and maintaining protection relays and other substation intelligent electronic devices (IEDs). Built for utility engineers, OEMs, and test labs, it streamlines setup, monitoring, and control so you can validate interoperability and quickly resolve communication issues in the field or the lab.

Key capabilities:

• Master-side communication with IEC 60870-5-103 devices over serial interfaces (e.g., RS-232/RS-485) with configurable link parameters.
• General interrogation, time synchronization, directory/read operations, and select-before-operate control commands, as supported by the target device.
• Real-time frame capture and decoding with clear ASDU and information object breakdown, timestamps, filtering, and search to accelerate troubleshooting.
• Retrieval and viewing of events, measured values, and disturbance/fault records when provided by the IED.
• Safe test workflows with read-only modes and confirmation prompts to prevent unintended operations.
• Repeatable test sequences and comprehensive session logging, with exportable reports for audits and documentation.
• A user-friendly interface with device profiles and saved configurations to speed commissioning across projects.

With ProTester IEC-103 Master, teams can reduce commissioning time, improve maintenance efficiency, and confidently verify IEC 60870-5-103 communications across multivendor environments.
