DTM for IS1 Field Devices Now Certified

Press release date: Apr 30, 2009

HOUSTON - R. STAHL has been providing a Device Type Manager (DTM) for the IS1 remote I/O system for some time. This DTM enables users to fully con-figure, set parameters and administration of all I/O modules, CPM unit (gateway) and connected HART field devices via Profibus DP through an FDT-capable program (FDT frame application). The DTM has been tested by means of the dtmINSPECTOR, this is the official DTM test and certification tool of the FDT Group, the version has been certified since 2008. This ensures full interoperability of the IS1 DTM with corresponding FDT frame applications which assures users of reliable access to the data and status variables during commissioning and operation of the system.

R. STAHL's IS1 DTM provides users with an integrated solution whose functional range is presently unique in the market. All data, e.g. parameter, serial numbers as well as diagnostic and error messages about the IS1 system and connected field devices is made available for analysis through suitable diagnostic tools and asset management systems. Thanks to integrated condition monitoring functionality, the DTM not only allows for parameterization, but also enables cyclic monitoring of connected HART field devices, provided that this is supported by the FDT framework.

The modular design of DTM allows for a flexible configuration of IS1 systems and facilitates extensions and modifications of existing structures via the frame application. Configuration data and parameters can be changed during operation without halting the process. All diagnostic and I/O status signals can be read and written without a connected automation system, which is especially beneficial during start-up and error diagnosis. Further functions allow users to generate an audit trail, print labels for I/O modules and import or export parameter data.

The DTM is also suitable for R. STAHL's new, Ethernet-capable IS1 version. The Ethernet version is combined with a Modbus TCP communication DTM developed for use with IS1 to ensure smooth system integration.
