  • Page 9: Safety Instructions

    European standard EN 50110 can be used as a guide. 2.2 Intended use The BMS-Ethernet gateway COM461MT connects the serial BMS bus to Ethernet TCP/IP networks. The gateway converts alarms, measured values and statuses from the BMS bus to the Modbus/TCP protocol. This allows connec- tion to Modbus networks.

  • Page 10: Address Setting And Termination

    Safety instructions 2.3 Address setting and termination In order to ensure proper functioning of the BMS-Ethernet gateway COM461MT, correct address assignment and termination of the BMS bus is of utmost importance. Assigning addresses that are already used by existing de- vices in the BMS or TCP/IP networks concerned may cause serious malfunctions.

  • Page 11: Product Description

    3.2 A short description The BMS-Ethernet gateway COM461MT contains a Modbus/TCP server that converts the BMS data for a Modbus client. A web server makes it possible to configure the COM461MT (see “Commis- sioning” on page 19). Ethernet-TCP/IP interface: The coupling is performed via the internal Layer-2 switch. Two Ethernet ports are available.

  • Page 25: Data Access Using Modbus/Tcp Protocol

    6. Data access using Modbus/TCP protocol Requests are sent to the Modbus/TCP server in the COM461MT using function code FC4 (read input register). The server generates a function-related re- sponse and sends it to the Modbus client. 6.1 Exception code If a request cannot be answered for whatever reason, the server sends a so- called exception code with which possible faults can be narrowed down.

  • Page 26: Modbus Requests

    The required words of the process image can be read from the input registers in the COM461MT using the function code FC4. For this purpose, the start ad- dress and the number of registers to be read need to be entered.
