Modifying Variable Values from the POU Body
It is possible to change the value of a variable from the POU body, in Monitor Mode. This can be
a toggle of a Boolean or writing a value to an Integer/Real value etc. To invoke this, double click
on the variable label, i.e. ENABLE. This dialogue will appear, click OK to toggle on, click OK
again to toggle off. If there is PLC code writing to this variable, then this will overwrite this action.
The dialogue box can be disabled, so that operation is simply by the mouse.
For Integer/Real variables, use the same procedure, i.e. double click on the variable name,
whilst in monitor mode. The new value can be entered either as decimal or as a hexadecimal
value.
Again, if there is PLC code writing to this variable, then this will overwrite this action.
NOTE Both operations also operate on direct MELSEC addresses (For further illustrations, see
previous section: “Functions”).
IMPORTANT TIP
When using the Ladder editor, hold down the CTRL key and double click on the variable name.
The actual address of the selected GV will then be displayed, as shown below. Repeating the
operation will toggle back to the identifier.
If Monitor Mode is stopped, then started again, identifiers are displayed.
