Implement virtual external inputs using various methods.
The CX-Simulator can generate/replay virtual external inputs using various
methods to verify program operation.
Replay input operation us-
ing the command log
Save the history of manual input operation (e.g. I/O set/reset by the CX-
Programmer and change of DM PVs) and settings by application programs,
as a command log file. The saved data can be used instead of the input to the
Ladder Engine by replaying using the data replay function as required.
Replay inputs using traced
data
Replay the data of data trace obtained from the actual PLC by the CX-
Programmer or the data monitored via a time chart, as inputs to the Ladder
Engine using the data replay function.
Replay inputs using the data
reply file
Replay data of the data reply file (a CSV-format text file) as inputs to ladder
engine. The data replay file can be created using commercially available
spreadsheet software (e.g. MS-Excel).
Simulate I/O using a debug-
ging program
Hold a program to generate debugging data (debugging program) besides
programs for actual applications (application programs). Input data can be
produced using the debugging program. This capability enables to simulate
I/O. (Application programs and the debugging program share the I/O memory
areas.)
Generate inputs using I/O
Condition
When the contents of designated I/O memory area (bits or words) satisfy the
contents of condition expression; the values are set to the designated I/O
memory area after the designated delay time. Multiple expressions can be
set.
