We need to start both the PLC simulator (GX Simulator3) and the GOT simulator (GT Simulator3) to perform a simulation. First, start the PLC simulator (GX Simulator3).

(1) In GX Works3, open a sequence program (described on the previous page).
(2) In GX Works3, select [Debug] → [Start Simulation] from the menu.
(3) The [Online Data Operation] dialog appears and the simulator (GX Simulator3) starts.
