Monitoring I/O in Ladder

Instances
Note
3. A function block called FunctionBlock1 will be automatically inserted after
the Function Blocks icon. This icon contains the definition of the function
block.
4. Double-click the FunctionBlock1 Icon. The variable table and algorithm
will be display.
After a program containing function blocks has been created, it can be down-
loaded from the CX-Programmer to an actual CPU Unit that it is connected to
online. Programs can also be uploaded from the actual CPU Unit. It is also
possible to check if the programs on the CX-Programmer (personal computer)
and in the actual CPU Unit are the same. When the program contains function
blocks, however, downloading in task units is not possible (uploading is possi-
ble).
The following procedures can be used to monitor programs containing func-
tion blocks.
With the CX-Programmer Ver. 6.0 and later versions, it is possible to monitor
the status of bits and content of words in a ladder program within an instance
when monitoring the program. To monitor I/O bits and words (I/O Bit Monitor),
either double-click the instance or right-click the instance and select Monitor
FB Ladder Instance from the pop-up menu. At this point, it is possible to
monitor bits and words, change PVs, force-set/reset bits, and perform differ-
entiation monitoring.
(1) It is not possible to perform online editing or change timer/counter SVs.
Also, although monitoring the status of bits and words is possible for in-
put-output variables, changing PVs and force-setting/resetting bits is not
possible.
I/O values can be
