  "notes": "Source: MENNEKES, \"Description: access to AMTRON via MODBUS-TCP\", document Description Modbus_AMTRON HCC3_v01_2021-06-25_en (HCC3 controller), sections 3.1 to 3.4 -- the vendor's own register table, reached without a login at update.mennekes.de. The earlier pass recorded the AMTRON family as publishable only from the MENNEKES customer portal; the HCC3 description is public now, so the skip was re-checked and lifted. The document gives every register twice, as hex data address and as Modicon number; the hex address is the value placed in the message, which is what this file lists (zero-based). Modbus TCP server on port 502, unit identifier 0xFF, function codes 01, 02, 03, 04, 05, 06 and 0F; the server must be enabled in the service interface and is inactive in the operation modes 'Energy Manager' and 'SCU'. This is the HCC3 controller family (AMTRON Xtra / Premium). The AMTRON Professional, Twincharge and AMEDIO lines run a Bender CC612/CC613 controller with a completely different map and are covered by the bender-cc612-cc613 seed instead."
