COPA-DATA to unveil SCADA Logic at SPS / IPC / Drives
n a SCADA application it is often necessary to execute logical operations in order to calculate interdependences between PLCs. For this, independent HMI/SCADA package zenOn provides a Mathematics driver and support for VBA script integration. If the limits of the Mathematics driver are reached, or if the user is reluctant to program in VBA, COPA-DATA GmbH now offers an easy and powerful solution.
The IEC 61131-3 soft control platform STRATON can be used as the head controller in an application. Whilst running as a background process, STRATON takes over the complex calculations required for control tasks. STRATON has no negative effect on the zenOn runtime, ensuring the safety of the application. The integration of STRATON in zenOn results in a SCADA system with integrated PLC logic, called SCADA Logic.
Users of SCADA Logic do not need to learn the VBA syntax, because STRATON is programmed using familiar IEC 61131-3 programming languages including FDB, LD, IL, ST and SFC. A cyclic execution guarantees a valid process image for the SCADA system at all times. If required, several instances of STRATON can run simultaneously to share tasks in a structured way.
