DF PROFI II PCI/PCIe/CPCI/PC104+
High performance PROFIBUS DP/DPV1 interface
The DF PROFI II is a high performant PROFIBUS DP/DPV1 board of the newest generation and is available as PCI, PCIe, CompactPCI and PC104+ board. The DF PROFI II PCI interface supports 5V and 3.3V 32 Bit PCI slots, so it can be used in server pcs and workstations without problems. Beside the standard DP/DPV1 PROFIBUS services the board implements useful additional options.

The implemented hardware watchdog allows the electrical switch off of the PROFIBUS interface, that allows the board to be used in redundant DP Master concepts with 2 pc systems.
The process image contains except I/O data and status information a relative time stamp with millisecond resolution.
The DF PROFI II board needs for the data exchange of the process image only round about 1 ms with common I/O data sizes up to 3 Kbytes and stores the PROFIBUS configuration data in a failsafe flash memory.

For the compilation of the PROFIBUS configuration a very powerful and comfortable tool is available. The DF PROFI II board supports beside the popular operating systems Windows 2000/XP and Linux (SUSE, Redhat, Fedora) real-time operating systems like LINUX RT and LabVIEW RT.

COMSOFT PROFIBUS Configuration Tool
CONFIGURATOR II
CONFIGURATOR II is a powerful PROFIBUS configuration tool. It does not charge the user with difficult PROFIBUS details and supports a full graphical GSD file based DP Slave configuration as well as the comfortable compilation of OPC-Tags.

Powerful and extensive download, analysis and control functions permit an efficient start- and check up of the configured PROFIBUS DP network. The compiled PROFIBUS configuration is stored in XML format that allows an easy integration into third party tools.

COMSOFT Redundant OPC Server
The DF PROFI II Data Access OPC-Server is implemented as Free Threading/Multi Threading server for optimum performance and supports DPV0 Master class 1 and DPV1 Master class 2 services.

For the use with safety critical applications the DF PROFI II OPC-Server supports DPV0 Master class 1-redundancy with 2 pc systems. This feature guarantees a seamless takeover and an uninterrupted continuous processing of the connected DP Slaves by the standby system if the operational system fails. The DF PROFI II hardware design allows here the simultaneous connection of 2 DF PROFI II boards with identical bus addresses to the PROFIBUS network without problems.

COMSOFT FDT 1.2 Communication DTM
The available FDT 1.2 Communication DTM allows the use of the DF PROFI II board within any FDT 1.2-capable container programs for DP Slave configuration. FDT container programs are included in many process control systems. They are also available as stand alone solutions, e.g. Pactware of the Pactware Association.
