The systems we develop often work in slave mode and are controlled by a super ordinate PLC or exchange data and results for protocol reasons with the production control system.
Data exchange or the reception of control commands is done over all common used communication protocols like Profibus, ProfiNet, Modbus, TCP/IP, etc. or over I/O direct connections.
If required also database connections (Access, Oracle) are realised to e.g.: receive necessary information for the measurement process or to report results due to your specifications.
