Configurable multiple port connectivity

The Rosemount 2460 has eight slots for communication interface boards. These boards can be individually configured for

communication with hosts or field devices. The Rosemount 2460 supports a number of host communication interface standards

such as Ethernet, TRL2, RS485, and RS232. For field communciation TRL2 and RS485 are supported, as well as other standards such

as Enraf BPM and Digital Current Loop (Whessoe).

Modbus TCP communication to host

One of the system hub’s three Ethernet ports is used for Modbus TCP connection to host systems. By simply connecting the system

hub to the existing LAN network, communication over Ethernet is established:

■ Easy access, no special converters required

■ Fast communication

■ No need for dedicated cabling

■ Can be connected to TankMaster or other hosts

User-defined Modbus mapping

The Rosemount 2460 can easily be integrated into existing hosts as it can be configured to match the existing value mapping of the

current system. It provides flexibility when replacing legacy devices as it can be set up to match the old device without configuring

the host system.
