4-13-1 Debugging Screens and the User Program with a Virtual PLC

CX-Designer
The CX-Designer can simulate PT operations on a personal computer, so
screens created on the computer can be debugged using the test function
even without transferring the screens to a PT.
The CX-Designer can connected to a virtual PLCs running on the CX-Simula-
tor (i.e., on a user program execution engine). By using the CX-Simulator to
run programs created using the CX-Programmer, screen data and user pro-
grams can be debugged together on a personal computer.
CX-Simulator
The results of executing the user program
in the CX-Simulator are displayed on the screen.
Conversely, changes in values due to screen operations
are used as CX-Simulator user program inputs.
