1-3 Convenient Functions
The CX-Simulator provides the following convenient functions.
Monitor IR/DR
By Step Run, the contents of IR/DR for each task during ladder diagram exe-
cution can be monitored with the CX-Programmer SV monitoring, which has
been difficult to debug.
After setting break points to the mnemonic codes in the Step Run window,
executing the ladder diagram allows to monitor the value before the mnemonic
code is executed.
Block Run
Any range of a program can be executed by designating the execution start
point (the start pointer) and execution interrupt point (the break pointer).
Support debugging of ap-
plication programs on the
computer
When developing a monitoring program or a data collection program on the
computer, debugging communications functions was done with the actual PLC
connected. If the CX-Simulator is used together, on the other hand, a single
computer will do all of the debugging. (Valid only for application programs
using FinsGateway.)
Coordinated functions with
commercial software
Coordinated functions with commercial spreadsheet programs and text editors
allow using familiar software for data collection/display.
