Tag window
Description
Unlike the case when creating the user program, in function blocks you do not work
with direct addresses but with so-called tags. The addresses are assigned auto-
matically in a memory area which is not directly accessible to the programmer (Pre-
fix R, area R300 .. R6FF). The entries in the table are marked by different colours,
whereby:
Yellow Cells may be edited by the programmer.
Grey Cells are filled in automatically by PROTECT-PSCsw and cannot be edited
by the programmer.

IN/OUT
These cells mark the previously defined inputs/outputs.

Tag name
Clear reference to an address/timer/edge detection contact. Under this name the
address/timer/edge detection contact is activated during programming. A tag name
consists of a maximum of 9 alphanumeric characters incl. underlining. No differen-
tiation is made between lower case and upper case letters.

Setup value
This column can only be edited for the timer attribute. The set time (see Chapter
6.10.5) of the timer can be entered here. A tag name can be entered here too. A
modification in this column is only accepted in the ladder diagram after the activa-
tion of the switch [Assign] in the property dialogue.

Data type
The data type belonging to the tag name.
PS library : only the data types BOOL (e.g. M123, D0123-F) and WORD (only
when a timer is used) are available here. The data type WORD is automatically set
when a timer is used; a manual selection of the data type WORD is not possible.
PN library : the data types BOOL, WORD and BYTE are available here

Address
The address is automatically filled in with the exception of the ‘EXTERN’ attribute.
