Abstract
A controller for use in connection with a central control for a glass sheet processing system including an operator interface and a master computer, the controller including a slave computer, a port for two-way communication of data signals between the master computer and the slave computer, a position encoder corresponding to each of the movable components monitored by the controller, and a port for communicating a digital signal representative of the position of the movable component, issued by the position encoder, to the slave computer. The slave computer includes logic for receiving position information from the position encoders and continuously comparing this information to preselected position parameters downloaded from the master computer to determine whether an unsafe condition exists, sending a signal for deactivating the power switch to the drives for the affected components, and sending an error condition message back to the master computer.
