R. STAHL provides a new device type manager (DTM) for the IS1 remote I/O system, which not only ensures a more comprehensive information exchange between HART field devices via PROFIBUS DP V1, but also allows for complete integration of the IS1 system into FDT frame applications. The DTM retains all extended functions of STAHL's HART gateway DTM, such as automatic topology generation, configurable slave address, HART live list, error diagnosis and I&M functions. The entire remote I/O system – all I/O modules as well as CPM unit – can now be fully configured, parameterized and administrated by means of DTM via an FDT-capable program. All data about the system and connected HART field devices is thus made available for analysis through suitable diagnostic tools and asset management systems. Moreover, a growing number of control systems provides direct support for FDT/DTM technology through integrated features. IS1 DTM was designed to completely replace conventional solutions with GSD files for Profibus slave systems – a DTM-compatible DP V0 master exclusively uses DTM for the parameterization of and communication with IS1 components. DTM design 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. Diagnostic and I/O status signals can be read and written without a connected automation system.
