Process and a control device for a motor output suitable for being controlled through a communication bus

A process for controlling a motor, comprising:

• locally controlling starting and stopping of a motor using a local control device remotely connected to a master controller;
• monitoring said motor with a sensor which can be activated by an information condition of an automation system;
• stopping the motor using the local control device when information from the sensor is received by the local control device indicating that the sensor is in an activated state;
• stopping said local control device when the sensor is activated by the automation system;
• sending stop information from the local control device to said master controller indicating the motor has stopped;
• sending a command from the master controller, after receipt of the stop information, to the local controller for the local controller to unlock the local control device controlling the motor;
• and
• sending a start command from the master controller to the local controller to start the motor and switching the sensor out of the activated state after sending the start command.
