is HRT CommDTM

The Device Type Manager isHRT CommDTM is compatible to all FDT 1.2.1 compliant frame applications (Pactware, Fieldcare etc.).

It requires the isHRT USB communication interface as its hardware base. The CommDTM takes care of the management and configuration of the communication interface. It replaces the vendor specific configuration software with a standard FDT approach. The CommDTM can be compared to a device driver which facilitates the communication between the field devices at the HART bus and their device DTMs. It therefore supports the commissioning of the field devices from one central workstation. The communication interface can be employed as a primary as well as a secondary master. The configuration window of the CommDTM enables the user to switch between the two options. The retry limit and the number of preambles may also be set through the configuration window.
