HIM Smart HART Loop Interface and Monitor Takes Advantage of Legacy Instruments The device lets you leave existing smart HART transmitters and valves in place, yet still take advantage of all the information they have to offer. The HIM The Moore Industries HIM HART Interface Module unlocks the full potential of new and in-place HART multivariable transmitters, valves, meters and other smart instruments.

HIM Smart HART Loop Interface and Monitor Configuring the HIM One of the benefits of the HIM is that there are no internal or external controls to adjust or settings to change. All operating parameters are set using the PC Configuration software. Once these software settings are made, they are downloaded to the monitor in the form of a Configuration File and stored in the unit’s non-volatile memory. You can choose to save a backup copy of the file on your PC hard drive or external media.
HIM Smart HART Loop Interface and Monitor Mounting The HIM is designed to snap easily onto 32mm, G-type (EN50035) or 35mm Top Hat (EN50022) DIN rails. Installing the HIM There are two methods for connecting the HIM for configuration. The recommended method requires you to install the instrument into the loop before it is configured. The secondary method allows you to bench check the HIM by attaching it to test equipment that will simulate the input and monitor the output.
HIM Smart HART Loop Interface and Monitor EMC (Electromagnetic Compatibility) directives (EN55011, EN 50082-1, EN50082-2, etc.). Consult the factory for the most current information on products that have been CE certified. • All input signals to, and output signals from, Moore Industries’ products should be wired using a shielded, twisted pair technique. Shields are to be connected to an earth or safety ground at the unit itself.
HIM Smart HART Loop Interface and Monitor Bench Checking the HIM If you would like to configure the HIM before attaching it to the loop, you need to hook it up with the equipment listed in Table 1. Refer to Figures 5 and 6 for instructions on how to bench check the HIM either with or without taking advantage of the Transmitter Excitation (+TX) terminal. If you need further descriptions of the terminals, see Table 2. Figure 5.
HIM Smart HART Loop Interface and Monitor PC Configuration Software Figure 7. HIM PC Configuration Software Screen 3 2 1 The HIM PC Configuration Software can be used to program all of the HIM’s parameters. Once the default configuration has been saved, it is safe to program other parameters. The PC Software is made up of these sections: 1. HIM Status and Information Section–The left side of the screen includes seven boxes that display the different settings of the attached HIM.
HIM Smart HART Loop Interface and Monitor HART Parameters To program the HART parameters, change the settings in the Communications Settings box, then press Quick Set. See the descriptions below of the various sections of the screen. HART Address The HART Address is the address of the HART device that the HIM will be monitoring.
HIM Smart HART Loop Interface and Monitor seconds. In this example, we will use seven seconds. The HIM then sees its slave device speak and waits seven seconds for it to speak again. As long as the HIM sees a new message from its slave device its outputs are updated based upon the measured variables. If the slave device does not speak within the seven second period, the HIM declares a “No HART” situation and sends its outputs to the failed communications values.
HIM Smart HART Loop Interface and Monitor HART Device Info This box displays the identification and revision information of the monitored HART instrument. HART Device Status The HART Device Status box displays the current status of the monitored HART transmitter. In a small double-box, the software displays the code (hex number) associated with the status. Variables The device will monitor up to the first four HART variables sent by your transmitter.
HIM Smart HART Loop Interface and Monitor Alarms Parameters The Alarms tab controls the programmable alarm trip(s) option. This screen will be grayed out if the attached HIM is not equipped with at least one alarm trip. To program the Alarm parameters, change the settings in the Alarm1 and/or Alarm2 box, then press Quick Set. The sections of the screen are described below. Figure 10.
HIM Smart HART Loop Interface and Monitor HART Additional Status Alarm Bits HART Additional Status also called “More Status” and “Command 48” is where device manufacturers install the custom diagnostics for the specific device. For your particular application, you may choose all of these diagnostics to cause the HIM relay to trip or just one diagnostic bit to trip the HIM relay (or any combination in between). The manufacturer of the HART device will be the source for the specific diagnostic information.
HIM Smart HART Loop Interface and Monitor Analog Outputs Parameters The HIM comes with either two (–2AO) or three (–3AO) analog outputs. The Analog Outputs tab allows you to specify which HART variable is to be monitored as the source of the analog output, the input range and output range, and how the output will react when the variable input is out of range. To program the Analog Outputs parameters, change the settings in the Output1/2/3 boxes, then press Quick Set.
HIM Smart HART Loop Interface and Monitor Configuring Analog Output Trimming The Analog Output Trimming section of the software allows you to match the HART monitors analog output to the output measured by a calibration device. This will require a calibrated multimeter, such as a HP Model 3478A or equivalent, accurate to ±0.009%. Note: Trimming the analog output of the monitor nullifies any scaling that may have been performed in the Scaling tab.
HIM Smart HART Loop Interface and Monitor Custom Curve Parameters The custom curve tab allows you to set up a custom curve of up to 128 points. A custom curve can either be created from scratch or loaded from a previously created comma separated value (.csv) file. To program the Analog Outputs parameters, change the settings in the Custom Curve tab, then press Download Table. See the descriptions below of the various sections of the screen. Figure 14.
HIM Smart HART Loop Interface and Monitor Figure 15. Scaling Tab Scaling Parameters The Scaling tab allows you to configure the values for scaled variables. To scale the selected variable, enter the values into the appropriate boxes, then click on the Transfer menu and click Download to transfer the new scaled values to the HIM. (If any scaled variable was selected in the Display, Alarm or Analog Outputs tabs, then the corresponding scaled variable section will become active for editing).

HIM Smart HART Loop Interface and Monitor Appendix A: HIM MODBUS Feature Comms Settings The HIM PC program allows you to configure the HART monitor. A HART Monitor with the MODBUS option provides a digital MODBUS output to a connected MODBUS-based controller. Selecting the MODBUS tab allows you to set the MODSBUS communications parameters. Notice that the MODBUS tab will only be available in units with the MODBUS option.
