A robot controller including a control unit and a portable device (TPU) for teaching and manually operating the robot. The TPU includes safety equipment, a safety TPU-part having a first communication unit and a main TPU-part having a third communication unit. The control unit includes a safety control part having a second communication unit and a main control part having a forth communication unit. The first and second communication units form a first communication channel for transferring data from the TPU to the control unit. The third and fourth communication units form a second communication channel for transferring data between the TPU and the control unit. Each of the main TPU-part, safety TPU-part, main control part, and safety control part includes a processor for generating and/or handling the data. Each communication unit is connected to a network and forms a node in the network.
