HART-compatible multiplexers are ideal for users who want to interface with a large number of HART devices. Multiplexers can be modular and are capable of supporting both point-to-point and all-digital (multidrop) HART communication modes. Communication between a multiplexer and a host application depends on the multiplexer capabilities (e.g., RS232C, RS485, Modbus, and TCP/IP Ethernet).
When installing HART multiplexer systems, the following capabilities should be considered:
- Number of HART channels supported
- Number of HART channels that share a HART modem
- Burst mode support
- Multidrop support
- Method of communication with the host computer or control system
