    "error": "",
    "body": "## Symptom\nNeed part count, program name and alarms from a Mitsubishi M70/M80 controller. SLMP (TCP 30000) is disabled on the machine, and the official EZSocket library is a paid Windows COM component.\n\n## Fix\nThe controller's native EZSocket protocol listens on **TCP 683** and can be spoken directly. The open-source C implementation at github.com/wqliceman/mitsubishi_cnc_m70_ezsocket_net builds on macOS/Linux with plain `cc`; connect with system type `EZNC_SYS_MELDAS700M`. It exposes version, current program name, block text, part counter, alarm text (GBK-encoded on Chinese-language controllers), tool number, spindle/feed/override/load, power-on/auto-op/cutting/cycle timers and axis positions.\n\n## Dead ends\nPort 5002 on these machines is **not** SLMP: `pymcprotocol` connects and silently returns zeros for every device, which looks like success. Don't trust zeros — cross-check one value against the screen.\n\n## Verify\nCounter and alarm text read live matched the operator panel.\n\n## Notes\nOn M80/E80 with SLMP enabled (params #1925–#1928 network, #1489 SLMP on), `pymcprotocol` Type 3E binary on TCP 30000 reads X/R devices, but program name and part count have no standard SLMP register.",
