We live in an era where digitalization is key for companies to improve production and keep themselves competitive. However, although the market has many types of field network, most field devices still run on analog, and most have the HART communication protocol. The ProComSol HM-USB-ISO USB HART modem belongs into this category.

HART is far from new in process automation, but that doesn’t make it obsolete yet. Indeed, the updated protocol provides the same level of information as a digital version.

In the article here, we review a USB HART modem from ProComSol, the HM-USB-ISO. It can connect field devices with different device configuration software too.

ProComSol HM-USB-ISO USB HART modem specifications

The ProComSol HM-USB-ISO provides an essential service for field technicians and engineers around the world. Some devices give access to the configuration menu through the local display, but you have some downsides here. When you can only access the configuration through the display, you have to go to the devices in the field. You also have to know how to navigate different displays and the menu tree.

The ProComSol HM-USB-ISO gives you flexibility by allowing you to access the device menu through the panel. Plus, the software interface apps for your smartphone, such as DeComm 2000 or DevComDroid, offer a better user experience than the standard displays.

ProComSol HM-USB-ISO features

If you have HART devices in your plant from any brand, the ProComSol HM-USB-ISO can access all of them. The interface has a USB 1.1 and 2.0 connection for your use. It also has a test program to identify the interface and port on your computer.

Of course, you have to have device configuration software to access all the information. ProComSol offers three good options. The DevCom2000 Smart Device Communicator is based on Windows and uses device description files.

If you want a mobile solution, you can use the DevComDroid Smart Device Communicator for Android or DevCom.IOS Smart Device Communicator for IOS devices. However, if you use one of these, you can’t use the USB HART modem; you need to get the Bluetooth one.
