The MVI56-HART Master Multi-drop Network Interface Module allows ControlLogix I/O compatible processors to easily communicate with HART slave devices. The MVI56-HART module interfaces up to 15 devices on each HART channel with the ControlLogix processor. Four channels on the module support master protocol commands to interface with slave devices on their own networks. Each port is individually configurable. Data is exchanged between the HART network and the ControlLogix processor using the internal database contained in the module and direct control by the processor's ladder logic and pre-defined data objects (5000 registers maximum). The MVI56-HART module is the perfect solution for industrial applications in chemical and refining operations, gas and liquid distribution systems, and remote offshore monitoring stations, addressing virtually all aspects of control, data acquisition, and maintenance.
