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

4.2 Purpose The HRM2008 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 All the HART™ information is passed through the RS-485 or Ethernet port, for maintenance purposes and connectivity to HART OPC server and/or AMS (Asset Management Software). Acting as HART OPC client, a maintenance workstation PC can use this port for configuration, maintenance, calibration, diagnostics, and data access to all connected 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 default configuration uses 14 holding registers per channel and can be modified to meet your applications using the configuration web page. The information can be accessed using standard Modbus / TCP-IP protocol.

6 Features

6.1 Two Ethernet-Switch Ports The HRM2008 is equipped with two Shielded Ethernet Switch ports, used to daisy chain multiple modules.

6.2 4-20mA Pass-Through The 4-20mA signals for each channel are accessible via the HE10 connector. Various ‘quick connect’ cables are available for easy connection to PLC analog input/output modules.

6.3 Built-in Filters and Resistor Terminations The HRM2008 has three sets of 8 'dip switches'. Each channel has one 'dip switch' assigned from each of the sets. The first switch is used to provide internal 250 Ohms resistor loop impedance when the PLC analog input does not provide it. The second switch is used to enable the filtering of the HART information when a “smart” valve is used. The third switch is to close the current loop when the module is used without an analog I/O card.


11

6.4 DC to DC Converter The HRM2008 has two 24 VDC power inputs; both can be supplied with one source. The first 24Vdc input is used to supply HRM2008 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.

7 RS-485 Pass Through Operation

7.1 Connections Details The Pass-Through port is the RS 485 port. It can be configured as 2 wire or 4 wire depending on the need. Connection details for the port:

To use the port in the 2 wire mode short the RX+ and TX + externally and use it as the +ve (B) line. Short RX- and TX- externally and use it as the –ve (A) line for the communication.

8 Hardware To connect field devices, 3.81mm pitch 8X6 pole double deck connector is used; six poles per channel are needed. For the control system analog input or output module, the Quick Connect HE10 connectors are used (please refer to Appendix A for a list of available cables and pin-out diagrams).

8.1 DIP-switches S1, S2 and S3 Switch S1 : used to bypass the 250 Ω line impedance of the module. Switch S2 : used to connect the filtering capacitor. Switch S3 : use the module without analog IO card.

Switch Settings Operating modes (Analog passthrough side) S1 S2 S3

a. Without Analog I/O module OFF OFF ON

b. With Analog Input module with filter OFF ON OFF c. With Analog Input module without filter ON OFF OFF d. 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. A series 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)

Figure 2: Representation of one HART Channel Refres h count Status register of HIM

10.2 MODBUS Holding Registers (460011) MODBUS holding register 460011 keeps the status of Rescan of HIM. This register contains two different 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. If this 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 request are sending manually. The second field has no meaning if the rescan mode is auto. This 8 bits corresponds to 8 HART channels of HRM and if any users wants to connect channel manually then they make a zero to one transition on that particular bit which corresponds to requested channel i.e. same as what we are doing on Web Server for Rescan.

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 using a 360°s shield-bonding cable component, on the other end of the cable, the shield should be cut close to the cable isolation end and isolated using for example a thermal shrinkable isolator.
