Integrated Simulation for the Entire System
Section 4-13
4-13-2 Debugging Screens and the User Program with the Actual PLC
With CX-Designer, simulation can be executed with the personal computer
connected to an actual PLC. This enables debugging (including monitoring
and settings) using actual I/O Units, Special I/O Units, and CPU Bus Units
connected to the PLC, as well as data from external devices and PLC data on
the network.
The results of executing the user program in
the actual PLC are displayed on the screen,
along with the status of external devices.
Conversely, changes in values due to screen
operations are used as the actual PLC user
program inputs and in the set values for
external devices.
