This article describes technological level of flexible manufacturing system (FMS) control. It focuses on the control in terms of sensors, actuators and technological networks. It also focuses on the control of manipulators that are part of FMS and are controllled via the network DeviceNet. Flexible manufacturing system (FMS) represents fully automated technological manufacturing process that is employed in teaching process. The principal aim is to improve the control system of a given model as well as higher levels of distributed control system (DCS) using the communication links between individual DCS levels.
