An information processing device includes an actuator emulator that simulates a behavior of a drive apparatus that is for driving a first control target, an actuator emulator that simulates a behavior of a drive apparatus that is for driving a second control target that cooperates with the first control target, a timer that generates a virtual time, and an execution part that executes a PLC program for controlling the actuator emulator and a robot program for controlling the actuator emulator. Execution modes of the control programs used by the execution part include a synchronous execution mode in which the PLC program and the robot program are synchronously executed in accordance with a virtual time and an asynchronous execution mode in which the PLC program and the robot program are asynchronously executed.

The present invention relates to a computer program for producing a graphical user interface (100) of a manipulator program and to a method for navigation through a manipulator program, wherein the manipulator system (1) controlled by the manipulator program comprises at least one manipulator (30). The manipulator program comprises at least one set-down point (AP1 to AP5). The user interface (100) has a graphical program progress indicator (150) which indicates the current program progress of the manipulator program and the at least one set-down point (AP1 to AP5) of the manipulator program. The at least one set-down point (AP1 to AP5) indicated can be selected by a user, and the manipulator program is set up to control the manipulator system (1) in such a manner that the system assumes a system state assigned to the selected set-down point (AP1 to AP5) in response to the selection. The method comprises the steps of: providing a manipulator program; producing the graphical user interface; stopping the manipulator program; receiving a selection of a set-down point on the program progress indicator of the graphical user interface; and guiding the manipulator program to the selected set-down point, with the result that the manipulator program controls the manipulator system in such a manner that the system assumes the system state assigned to the selected set-down point. Such navigation may be advantageous, in particular, in the field of debugging, error correction and parameter correction or parameter optimization.

An intelligent function unit includes an input selector selecting, as an input signal, an actual input signal or a simulated input signal generated in advance; an output selector selecting whether to output an output signal to the second controlled device; and a calculator causing an input/output controller in which combination and order of use of general circuit blocks are set to process the input signal one step at a time and transmit the output signal to an engineering tool or causing the input/output controller in which combination and order of use of the general circuit blocks are set to process the input signal consecutively for a set period of two or more steps, store the output signal for each step in a logger, and transmit an output signal corresponding to the set period and stored in the logger to the engineering tool.
