In the industrial processes the positioning with high accuracy is really important. In this paper we controlled an electro pneumatical and an electrical powered linear axes. The pneumatical part of this model (a pneumatical transporter with magnetic clutch) is moving to the x direction, and the electrical part (servo engine with its linear axis) is positioning to they direction. The communication network is created with the PLC (Programmable Logic Controller) via CANopen protocol (based on CAN –Controlled Area Network- industrial standard bus) and FHPP (Festo Handling and Positioning Profile) data profile. We used a PID controller (proportional-integral-derivative controller) for the pneumatic positioning, and made it in the PLC program.
