Monitoring Word and Bit Status of Ladder Programs in Function Blocks
Previous version (Ver. 5.0) New version (Ver. 6.0)
The I/O status of a function
block instance’s ladder
diagram could not be
monitored while monitoring
the program online. (It was
only possible to check the
program in the function block
definition.)
The I/O status of a function block instance’s ladder diagram can be monitored while
monitoring the program online. To monitor the I/O status, either double-click the function
block instance or right-click the instance and select Monitor FB Ladder Instance from the
pop-up menu. At this point, it will be possible to monitor the status of I/O bits and the
content of words, change PVs, force-set/reset bits, and monitor differentiation (ON/OFF
transitions) of bits.
Note: Online editing is not supported and timer/counter SVs cannot be changed.

Registering and Monitoring Function Block Instance Variables in a Watch Window
Previous version (Ver. 5.0) New version (Ver. 6.0)
To register a function block
instance’s variable in a
Watch Window, it was
necessary to display the
Watch Window, double-click
the window, and select the
desired variable from a pull-
down list.
Multiple variables in a function block instance can be easily registered together in the
Watch Window. The FB variables registration Dialog Box can be displayed with any of
the following methods and the variables can be registered together in that Dialog Box.
1. Right-click the function block instance and select Register in Watch Window from
the pop-up menu.
2. Select the desired function block instance in the program or variable table and
either copy/paste or drag/drop the instance into the Watch Window.
3. Move the cursor to an empty line in the Watch Window and select Register in
Watch Window from the pop-up menu.

Other Improvements Related to Function Blocks
The cross-reference pop-up function is supported in ladder programs within
function blocks.
The ST language help program can be started from the pop-up menu in ST Editor.
A function block’s definitions can be opened just by double-clicking the function
block instance.
The cursor automatically moves down after a function block instance’s parameter
input is confirmed.
Other Improvements
Improvements to PLC Setup Downloading
When the PLC Setup is downloaded to a PLC, the serial port related settings (Host
Link Port Tab, Peripheral port Tab, and FINS Protection Tab settings) can be
eliminated from the download. (This function allows the user to protect against
overwriting from the CX-Programmer after using NT Link auto-detection from the
CX-Integrator or making changes with a PLC parameter transfer.)
