System software for the development of real-time applications based on fieldbus systems. Target operating systems are QNX6.x and PREMPT_RT Linux, as well as RTAI Linux. There is also offered an innovative graphical programming tool called DACHSview++.It is based on graphical function block display and allows the development of real-time applications, which are working fully event oriented. Access to OS primitives, as well as access to physical memory, IO ports and hardware interrups are supported. Any C/C++ code can e integrated by use of two different JIT compilers!For animated 2D and 3D graphics are different function block libraries profided.Supported fieldbus system: PROFIBUS,PROFINET,CAN,CANopen,INTERBUS,DACHS,DACHSview++,SoftSPS,SoftPLC,Ethernet Powerlink,EtherCAT. Message passing communication works with ZeroMQ and MQTT.
