Title: Method of operating an injection molding machine

Abstract: In a method of remote monitoring or remote maintenance of an injection molding machine which has an SPC with at least one CPU for the operation of actuators of the injection molding machine in real-time, data are transmitted between the injection molding machine and a remote monitoring or remote maintenance workstation disposed at a remote location. In addition to real-time control operation of the actuators of the injection molding machine the SPC of the injection molding machine operates as a web server, by way of which a simultaneous communication connection can be made with two or more remote monitoring or remote maintenance workstations, wherein a CPU of the SPC performs both real-time control operations of the injection molding machine and also server functions for remote monitoring or remote maintenance. In addition for data transmission between an SPC and an operating unit, having a microprocessor, of an injection molding machine, the SPC and the microprocessor of the operating unit can communicate by way of a local network in which the SPC forms a server and the operating unit forms a client.
