ProSoft Technology’s PROFIBUS DPV1 Master Modules (PTQ-PDPMV1) are able to access field data from up to 125 PROFIBUS DP slaves directly over the backplane. Now with its latest enhancements the module introduces users to an even wider range of benefits the added security and reliability of Hot Standby functionality and the interoperability from Field Device Tool (FDT) and Device Type Manager (DTM) technology.The PTQ-PDPMV1 module with Hot Standby functionality allows a PROFIBUS network to be controlled by two Schneider Electric (Model SE 140 671 CPU) Quantum/Unity processors.
The redundancy creates a backup so that should the primary power source fail the secondary module will switch into primary mode in under 300 miliseconds, making the module ideal for applications where it is crucial to eliminate the risk of downtime.Per Carl Henning of Profibus Trade Organization, “We’ve had big segment growth due mainly to Profibus’ strengths in factory automation, safety applications, drives and motion control. These applications use PLCs and ProSoft’s ability to add Hot Standby (or automation failover) capability is an additional feature that will be helpful in these and other applications.”Another recent upgrade to the module was the addition of the support for independent Field Device Tool (FDT) and Device Type Manager (DTM) technology.
FDT provides a standardized interface between systems and field devices, simplifying configuration, and assisting in asset management.
