The CIFX WinAC driver is a extension DLL (CCX) for the SIEMENS SIMATIC WinAC RTX 2010 SP1 system and allows the SIEMENS SIMATIC WinAC system to access Hilscher CIFX based communication hardware form the SPS cycle.
Hilscher fieldbus interface cards are supplied in most common form factors and access is possible to all supported fieldbus systems like ASi, CANopen, DeviceNet, PROFIBUS. OpenModbusTCP and the Real-Time Ethernet bus systems like EthernetIP, EtherCAT, PROFINET. SERCOS etc. This als includes support of master (controllerd) and slave (adapter) devices.
Driver functions are accessed from STEP7 / TIA via FBs / FCs. At least two functions are needed to exchange I/O data during the program cycle and the I/O data are mapped into data blocks of the STEP7 program (one DB for input and one DB for output data).

The configuration of the CIFX WinAC driver takes place in one general configuration block (DB_CIFXConfig) and the fieldbus configuration is done by the Hilscher fieldbus system configuration software SYCON.net.
Furthermore, the driver is able to use SYCON.net exported PDI (Process Data Information) XML files to convert input data into the STEP7/TIA format and vis a vers.
Without such an XML file the driver creates a ony by one mapping of I/O data to the PLC input/output data blocks.

The dirver also includes a converter tool (SYCON.net XML to SCL Converter) allowing to create TIA importable SCL code, describing the input and output data blocks corresponding to the SYCON.net configuration.
