How to Upgrade Your HART 375 Field Communicator

The HART 375 Field Communicator is a handheld device that supports all HART and FOUNDATION Fieldbus devices from all vendors. It is designed to be user upgradeable via the Internet, which means you can add new device drivers and functionality without sending your communicator anywhere. Here are the steps to upgrade your HART 375 Field Communicator:

Connect your HART 375 Field Communicator to a PC using an IrDA port or a USB cable. The IrDA port enables transfer of configuration data between the 375 and AMS Device Manager as well as upgrading of new Device Descriptions and functionality[^1^]. The USB cable allows you to transfer files between the 375 and the PC.

Download the Easy Upgrade Utility from the Emerson website. This utility will help you check for available upgrades and download them to your PC.

Run the Easy Upgrade Utility and follow the instructions on the screen. You will need to enter your serial number and product key to access the upgrades. The utility will show you the available upgrades for your communicator and let you select which ones you want to download.

After downloading the upgrades, transfer them to your HART 375 Field Communicator using the IrDA port or the USB cable. The communicator will automatically detect the upgrades and prompt you to install them.

Restart your HART 375 Field Communicator and verify that the upgrades have been installed successfully. You can check the version number and device drivers on the communicator's menu.

Congratulations! You have successfully upgraded your HART 375 Field Communicator. You can now enjoy the benefits of having the latest device drivers and functionality for your field instruments.

Why Upgrade Your HART 375 Field Communicator?

The HART 375 Field Communicator is a powerful tool that can help you troubleshoot and calibrate HART smart digital transmitters and FOUNDATION Fieldbus devices. By upgrading your communicator, you can ensure that it supports the latest devices and features in the field. Some of the benefits of upgrading your communicator are:

You can access new device parameters and functions that may not be available on older versions of the communicator.

You can improve the performance and reliability of your communicator by fixing any bugs or issues that may have been reported.

You can extend the life of your communicator by keeping it compatible with the evolving standards and technologies in the field.

Upgrading your communicator is easy and convenient with the Easy Upgrade Utility. You don't need to send your communicator to a service center or wait for a long time to get it back. You can upgrade your communicator anytime and anywhere with an Internet connection and a PC.

How to Use Your HART 375 Field Communicator?

Once you have upgraded your HART 375 Field Communicator, you can use it to communicate with any HART or FOUNDATION Fieldbus device in the field. You can use your communicator in two main operational modes: point-to-point mode and multi-drop mode.

In point-to-point mode, the digital signals are overlaid on the 4-20 mA loop current. Both the 4-20 mA current and the digital signal are valid signalling protocols between the controller and the measuring instrument or final control element. The polling address of the instrument is set to "0". Only one instrument can be put on each instrument cable signal pair. One signal, generally specified by the user, is specified to be the 4-20 mA signal. Other signals are sent digitally on top of the 4-20 mA signal.

In multi-drop mode, the analog loop current is fixed at 4 mA and it is possible to have more than one instrument on a signal loop. HART revisions 3 through 5 allowed polling addresses of the instruments to be in the range 1â15. HART revision 6 allowed addresses 1 to 63; HART revision 7 allows addresses 0 to 63. In this mode, you can access multiple devices on a single loop and configure them individually or collectively.

To use your HART 375 Field Communicator, you need to connect it to the device you want to communicate with using a test lead set or a HART modem. You can then power up your communicator and select the device from the menu. You can view the device information, status, diagnostics, configuration, calibration, and test options on your communicator's display. You can also transfer data between your communicator and a PC using the IrDA port or the USB cable.
