Ladder monitoring by GOT
• When searching an STL command, use "S (state)" in a device search.
• The 32-bit counters are displayed in 32-bit fixed display in the device monitor.
• When using FX3U(C), if the memory capacity is set to 32,000 or higher with the GX Developer PLC parameters,
sequence programs cannot be displayed.
When displaying a sequence program with the GOT, set the memory capacity to 16,000 or less.
• Changes to T/C set values are reflected on the ladder monitor display only when they are made with the device
monitor or test function.
When a value is changed by numerical input or other object, the change is reflected on the display after the GOT is
restarted.
■5. Reading comment files
Only files with the file names (program names) with one-byte alphanumeric characters are applicable to the GOT.
When project data are created on GX Developer, use only one-byte alphanumeric characters for file names (program
names).
(1) The following shows the GOT operation when the program in a safety function block has the
target of the search operation.

Reflecting value changes in display of FX ladder monitor screen
For opening the test menu screen from the device monitor screen or user-created screen, even if
the set values of the timer and counter are changed, the changed values are not reflected in the
display of the ladder monitor screen.
For reflecting the changed values in the display of the ladder monitor screen, read the program
again.
The GOT adds and displays the ladder block that shows the FB definition name in the application
instruction format in the last row.
For the continuous search, when the program in the safety function block has multiple target
devices, the ladder block is added to the last row only one time.
The GOT displays the ladder block that shows the FB definition name in the application
instruction format corresponding to the searched step.
The GOT adds and displays the ladder block that shows the FB definition name in the application
instruction format in the last row and ends the defect search.
(The operaiton is the same as that when all the defective devices are searched.)
