Fig. 7-44 Table of local variables for the selected program block
Texts which are longer than the column width are truncated in all tables and the “~” charac-
ter is attached. For such a case, a higher-level text field exists in such tables in which the
text of the current cursor position is displayed. If the text is truncated with a “~”, it is dis-
played in the same color as that of the cursor in the higher-level text field. With longer texts,
it is possible to display the whole text by pressing the <SELECT> key.
For protected program blocks, it is possible to enter the password assigned in the PLC802
Programming Tool. Subsequently, the relevant program block is released for display in the
ladder diagram.
Selecting this softkey opens the selected program block; its name (absolute) is displayed on
the “Window 1/2” softkey.
Use this softkey to activate / deactivate the program status display. Here you can monitor
the current states of the network from the PLC cycle end. The states of all operands are dis-
played in the “Program status” ladder diagram. This LAD acquires the values for the status
display in several PLC cycles and then refreshes the status display.
