Debug Function

Simulation can be executed as the debug function.

Simulation function

The simulation function verifies the hardware logic written into the flexible high-speed I/O control module without wiring with
external devices.
With the configuration tool, create "simulation input data", the substitute for external input signals, and write the data into the
flexible high-speed I/O control module to operate the hardware logic.
Simulation results can be saved in CSV files. Saved results can be visually checked with GX LogViewer.
• During simulation, external outputs are actually turned on or off. Thus, execute the simulation under the
situation in which the module has not be connected with external devices or paying adequate attention not
to affect the system.
• Even though the simulation is executed with the hardware logic where an SI device terminal is linked, an
interrupt request to the CPU module is not output.
• Even though the simulation is executed with the hardware logic where an SSI encoder block has been
arranged, the communication with an SSI encoder will not be performed. Thus, position data of the SSI
encoder is not reflected to simulation execution results.
Window layout
The following describes the configurations of the "Simulation Settings" window. In this window, "simulation input data" can be
created and written into the flexible high-speed I/O control module or simulation is executed.
(Simulation input data is composed of external input signal data and "Simulation step unit time setting" in this window.)
