Method for operating a machine control system, and machine control system

A method for operating a machine control system

• having at least one machine controller for performing machine operations,
• having at least one machine, which is controlled via a control mechanism by the at least one machine controller, and
• having at least one mobile hand-held terminal, which is portable by an operator, for functionally influencing the at least one machine controller,
• wherein the at least one mobile hand-held terminal has at least one operating element for manually influencing the at least one machine controller for performing the machine operations and at least one user interface having a display for monitoring or controlling the machine operations by an operator, and
• wherein the at least one mobile hand-held terminal comprises at least one emergency stop actuation element for terminating the machine operations,
• wherein respectively present actuation states of the at least one emergency stop actuation element may be manually activated or changed by an operator and are coupled via at least one transmission interface into an emergency stop safety circuit or into a safety bus system of the at least one machine controller,
• the method comprising:
• schematically or abstractly up to photorealistically representing the machine control system or portions of the machine control system on the display of the at least one mobile hand-held terminal;
• schematically representing operational area(s) of the at least one emergency stop actuation element at the at least one mobile hand-held terminal using the display of the at least one mobile hand-held terminal and additionally using selective, fail-safe controlling of at least one lighting means at the at least one mobile hand-held terminal and/or at least one discrete lighting means in or at the at least one emergency stop actuation element at the at least one mobile hand-held terminal,
• wherein for signaling the operational area(s) of the at least one emergency stop actuation element, the schematically represented portion of the machine control system is graphically marked and/or highlighted in color or those schematically represented portions of the machine control system are graphically marked and/or highlighted in color on the display of the at least one mobile hand-held terminal for which portion(s) the at least one emergency stop actuation element is functionally available.
