"_comment": "rtu_over_tcp.json — RTU-over-TCP Modbus server for the integration suite (RTU framing tunnelled over a socket, as a serial→Ethernet gateway presents it). Byte-for-byte standard.json EXCEPT the server block: framer=\"rtu\" (not \"socket\") + port 5021 (not 5020), so it co-runs with the standard profile on :5020. pymodbus 3.13's simulator honors framer=rtu on a TCP server — confirmed on the wire (controller spike, 2026-07-24): raw RTU FC03 read of HR[5] returned `01 03 02 00 05 78 47`, a pure RTU frame with no MBAP header. Layout is identical to standard.json: HR[0..31]=address-as-value, HR[100]=auto-increment, HR[200..209]=scratch, coils 1024..1055=alternating, coils 1100..1109=scratch. NOTE: pymodbus rejects unknown keys at device-list / setup level; explanatory comments live in the README + git history.",
