Delta PLC Agent, 0 stars: one MCP server for AI-assisted work on Delta PLCs in AX, ISPSoft and WPLSoft

It works on isolated copies of the project and ties every change to the exact PLC model, source hash and revision, with a record of each operation. It also covers DVP serial monitoring.

For controls engineers on Delta hardware: let an agent analyze and edit a project copy while keeping a traceable record of what it changed.

field-probe: listens to an unknown RS-485 or CAN bus and works out the protocol without sending a single frame

Walking up to a cabinet with no register map is risky, because a wrong poll can fault live equipment. This tool stays in listen-only mode, infers baud rate, node IDs and register maps from traffic already on the wire, and hands the results to an agent.

For controls engineers doing brownfield surveys: map an undocumented Modbus, CAN or J1939 network before anyone touches it.
