The MACX MCR-S-MUX HART® multiplexer is used for the digital connection of up to 32 HART®-compatible field devices to a PC. The field devices are connected in the point-to-point operating mode via the MACX MCR-S-MUX-TB HART® connection board and communicate with the multiplexer via the HART® protocol. The HART® multiplexer communicates with a connected PC via an RS-485 bus.
The portfolio for HART® communication provides expertise from HART®-transparent interface modules and HART®-compatible field devices. In addition, the HART® multiplexer enables bidirectional communication with up to 32 HART®-compatible field devices and with up to 4,000 interconnected HART®-compatible field devices.More information
- Easy online configuration and diagnostics for HART®-compatible field devices
- Continuous documentation of process variables and states via PC or management system
- No influence on measured value processing due to parallel access to the HART® field devices
- Processing of more than 4000 channels on one PC, by connecting up to 128 HART® multiplexers with 32 channels each
Configure the temperature transmitters of the Field Analog product family universally via the HART® signal before installation or during commissioning. At the same time, the transmitters offer you the option of transmitting the measured values and diagnostics data to a connected control system via the HART® protocol for further processing.
The MACX Analog and MINI Analog Pro repeater power supplies/input and output signal conditioners feature HART® transparency. This enables bidirectional communication with the field device via the controller or a HART® handheld device. In addition, the HART® impedance can be increased in low-resistance systems via an additional resistor of the MACX Analog repeater power supply.
Practical example of HART® communication
The bidirectional HART®-compatible devices in the MACX Analog series enable HART® information to be integrated into separate engineering and management systems via the MACX MCR-S-MUX HART® multiplexer and the corresponding wiring modules. Corresponding COM servers also support further processing via Ethernet. This also means that limit and diagnostic values, and information such as the calibration state or status of intelligent field devices, are integrated impact-free into distributed control systems and remote calibration can be performed.
