1 Highway Addressable Remote Transducer (HART™)

The HART™ protocol makes use of the Bell 202 FSK standard to superimpose digital signals at alow level on top of the 4-20mA signal. This enables two-way communication and makes it possiblefor additional information beyond just the normal process variable to be communicated to/from asmart field instrument. The HART™ protocol communicates without interrupting the 4-20mA signaland allows a host application (master) to get two or more digital updates per second from a fielddevice. As the digital FSK signal is phase continuous, there is no interference with the 4-20mAsignal.

4.2 Purpose

The HRM0800 is a HART™ Interface Multiplexer unit, which allows access to 8 Channels HART™communications on existing 4-20mA loop.

4.3 Functions

At power up the module scans the 8 channels and retrieves all the HART™ Data (Manufacture ID,Device ID, etc.). This information is routed to three internal memory areas:

4.3.1 Pass-Through

PC can use this port for configuration of field instruments.

4.3.2 Embedded Web Server (HTML pages)

Most HART™ Data can be viewed on web pages using standard web clients (Internet Explorer 7.0,Fire Fox, Netscape, etc.).

4.3.3 4x Registers Mapping (Holding Registers)

All HART™ data from each detected device can be mapped to holding registers (4X). The defaultconfiguration uses 14 holding registers per channel and can be modified to meet your applicationsusing the configuration web page. The information can be accessed using standard Modbus / TCP-IP protocol.

6 Features

6.1 Two Ethernet-Switch Ports

The HRM0800 is equipped with two Shielded Ethernet Switch ports, used to daisy chain multiplemodules.

6.2 4-20mA Pass-Through

The 4-20mA signals for each channel are accessible via the HE10 connector. Various ‘quick con-nect’ cables are available for easy connection to PLC analog input/output modules.

6.3 Built-in Filters and Resistor Terminations

The HRM0800 has three sets of 8 ‘dip switches’. Each channel has one ‘dip switch’ assigned fromeach of the sets. The first switch is used to provide internal 250 Ohms resistor loop impedancewhen the PLC analog input does not provide it. The second switch is used to enable the filtering ofthe HART information when a “smart” valve is used. The third switch is to close the current loopwhen the module is used without an analog I/O card.

6.4 DC to DC Converter

The HRM0800 has two 24 VDC power inputs; both can be supplied with one source. The first 24Vdcinput is used to supply HRM0800 and the second 24Vdc supply input is re-distributed to supply the‘loop current’ for each channel. The supply of each channel is isolated using a DC to DC converter.The DC to DC converter can deliver 1 Watts to the connected load.

8 HardwareTo connect field devices, 3.81mm pitch 8X6 pole double deck connector is used; six poles perchannel are needed. For the control system analog input or output module, the Quick ConnectHE10 connectors are used (please refer to Appendix A for a list of available cables and pin-outdiagrams).

8.1 DIP-switches S1, S2 and S3

Switch S1 : used to bypass the 250 Ohm line impedance of the module.Switch S2 : used to connect the filtering capacitor.Switch S3 : use the module without analog IO card.

Operating modes (Analog passthrough side) Switch SettingsS1 S2 S3

a. Without Analog I/O module OFF OFF ONb. With Analog Input module with filter OFF ON OFFc. With Analog Input module without filter ON OFF OFFd. With Analog Output module OFF OFF OFF

With the above configuration we can do following configuration:a. Without Analog I/O module: Current loop is completed manually through switch or from

HE10 connector.b. With Analog Input module with filter: Loop is complete by connecting Input module in

series i.e. across analog passthrough.c. With Analog Input module without filter: Loop is complete by connecting Input module

in series i.e. across analog passthrough.d. With Analog Output mode : Loop is complete by connecting Output module in series

i.e. across analog passthrough.

8.2 HE10 Connection

The HE10 connection is used to connect the analog input or output module of the control system. Aseries of ‘Quick-Connect ‘ cables are available for the following analog IO cards:

ACO 130 00 High Density Analog Out I/O Module (8 Ch)ACI 040 00 High Density Analog In I/O Module (16 Ch)ACI/AVI 030 00 I/O Analog In Module (8 Ch Differential)ACO 020 00 I/O Analog Out Module (4 Ch)

10.2 MODBUS Holding Registers (460011)

MODBUS holding register 460011 keeps the status of Rescan of HRM. This register contains twodifferent fields. The detail of this register is showing below:

First field: 8th bit of 460011 register, is showing the rescan mode whether it is auto or manual. Ifthis bit is non-zero then auto rescan is selected and if zero then manual rescan is selected.

Second field: Lower 8 bits of 460011 register, is showing the status that, which channel requestare sending manually. The second field has no meaning if the rescan mode is auto. This 8 bitscorresponds to 8 HART channels of HRM and if any users wants to connect channel manuallythen they make a zero to one transition on that particular bit which corresponds to requestedchannel i.e. same as what we are doing on Web Server for Rescan.

Note: For the complete Command definitions, please refer to http://www.hartcomm.org

HART™ commands are divided in 3 types, the Universal Command, the Common Practice and theDevice Specific Command. For HRM0800, Device Specific Commands were divided in two groups,the DR for the read and the DW for the Write.

To facilitate the Modbus register mapping for Universal command 2 and 3, RC 2 and RC 3commands were created. These commands have been formatted to fit Modbus register.

Appendix A: Installation recommendations

12.1 Ethernet architecture

1) a higher level Ethernet network connects the gateway local switches together.2) The gateways may be connected to the local switch in open loop daisy chain or star topology.


35

12.2 Grounding topology according to north America principles

rules :1) Each cabinet or junction box must be connected to the local ground.2) The body of the device must be connected to the local ground.3) The shield of the cable connected to the gateway cabinet must be connected to the cabinet.4) In order to prevent from current flow in the cable shields due to local grounds voltage differences,only one point of each shielded cable must be grounded

For a good EMC characteristics, the shield of the cables should be connected to the cabinet usinga 360°s shieldbonding cable component, on the other end of the cable, the shield should be cutclose to the cable isolation end and isolated using for example a thermal shrinkable isolator.

DANGER : before working on the unconnected shield end of a cable (for example whenisolating the shield), it is mandatory to isolate the other end of the cable shield from theground, in order to prevent from a possible electric shock. Failing to this can lead tohuman injury or death.
