© PHOENIX CONTACT - 2012-05-03103246_en_01 MACX MCR-S-MUX Data sheet 1D e s c r i p t i o n The MACX MCR-S-MUX HART multiplexer is used for the digital connection of up to 32 HART-capable field devices to a PC. HART field devices are connected in point-to-point mode via a HART connection board and communicate with the HART multiplexer via the HART protocol. These HART signals are superimposed on the analog standardized signals (4 ... 20 mA) of the process variables. The HART multiplexer communicates with a connected PC via an RS-485 bus. The configuration and diagnostics of the connected HART field devices are implemented by the HART/OPC server or standard software tools, such as Cornerstone, AMS (Version 6.2 or later), PDM, PRM, FieldCare or PACTware. Conformance The MACX MCR-S-MUX HART multiplexer meets the following standards and directives: – Directive 94/9/EC – EN 61326 – VDE 0110 – HART Field Communication Protocol Rev. 6.0 WARNING: Risk of electric shock Observe the safety notes on page 4. Make sure you always use the latest documentation. It can be downloaded at www.phoenixcontact.net/catalog HART multiplexer

11 Startup

11.1 Starting the HART multiplexer

• Connect the flat-ribbon cable (supplied as standard with the module) to the HART connection board, e.g., MACX MCR-S-MUX-TB.
• Connect the HART connection board, e.g., MACX MCR-S-MUX-TB, to the 24 V DC supply voltage. The HART multiplexer scans all 32 channels (default setting) for connected HART field devices (CMD 0).

11.2 LED indicators on startup

(See also "Troubleshooting" on page 15)

11.3 Communication with field devices

Once scanning is complete, the HART multiplexer establishes communication with the HART field devices that are found. The "HART-Tx" and "HART-Rx" LEDs light up alternately. If no field devices are found when the HART multiplexer is started, both LEDs remain off. If modules are added later, they must be located and added using the PC software (e.g., in Cornerstone using "Learn" or "Add instrument"). HART communication is only possible if the control circuit resistance is between 230 Ωand 600 Ω. An additional resistor may be required. 250 Ω is sufficient in most cases.

103246_en_01 PHOENIX CONTACT 14 The following components are required: –F i e l d d e v i c e HART-capable Ex-certified, if necessary –S i g n a l c o n v e r t e r HART-penetrable Ex-certified, if necessary, for explosion protection through energy limitation (EX-i) of the circuit for the field device. For example, a repeater power supply that supplies the field device and forwards the process signal (4 ... 20 mA) with electrical isolation to a controller. – If required, a suitable terminal block in order to route the signal to the connection board. – HART connection board, PI-EX-MB-S/16-01-2/D- SUB Here, a maximum of 16 channels are connected per board. An FLK plug can be used to extend this to 32 channels by adding a board. – HART multiplexer Accepts the HART signal, which was previously decoupled capacitively, and forwards it via an RS-485 interface. A maximum of 32 field devices in succession can therefore communicate bidirectionally via a HART multiplexer. The flat-ribbon cable for connection to the connection board is supplied as standard. – Interface converter, RS-485 to RS-232 or FL COMSERVER – Ethernet cable (for FL COMSERVER only) – If necessary, a resistor for the signal cable A termination resistor may be required in the signal cable. According to the HART specification, a resistance value of between 230 and 600Ω is required for the transmission of the HART signal. – Power supply The converter, connection board, signal converter, and, if necessary, the field device must be supplied with 24 V. – Software, see "Software" on page 11

14 Repair and maintenance

We recommend that you only allow us to repair our modules. In exceptional cases, repairs can also be made by another approved body. The modules are maintenance free. Troubleshooting If the approaches described prove unsuccessful, please contact our nearest sales center. For a quick response, make sure you have the following information to hand: – Type and serial number –P u r c h a s e d a t a – Error description – Application (especially input/output circuit) Error detection Possible error cause Error removal "PWR" LED off Auxiliary voltage failure or module fuse faulty Check aux iliary voltage supply. If fuse is faulty, return the module for repair. "PWR" LED flashing Internal module error Swi tch module off/on. If LED keeps flashing, return the module for repair. "ERR" LED flashes briefly No HART field device found Connect HART field device and check connection. "HART" LEDs off No HART field device found Connect HART field device and check connection. "RS485" LEDs off No RS-485 bus connected. RS-485 interface not active. Connect RS-485 interface and check connection.
