Meaning
The tag enables the NC, PLC, GUD and drive data to be directly written to.
The "Component addressing" (Page 74) section contains details on address formation.
Attribute:
● name
Variable address
Tag value:
All alphanumeric terms are approved as tag values. If a value is to be written from a local
variable directly, the $ replacement operator preceding the name of the local variable should
be used.
Syntax:
<DATA name="<variable name>"> value </DATA>
Example:
<DATA name = "plc/mb170"> 1 </DATA>
...
<LET name = "tempVar"> 7 </LET>
<!— the contents of the local variables "tempVar" are written to
bit memory byte 170 →
<DATA name = "plc/mb170">$tempVar</DATA>
The tag enables the listed drive and machine data to be saved or restored.
Addresses are listed in lines. Chapter "Component addressing" (Page 74) describes how
addresses are formed.
Up to 20 temporary data lists can be created.
Attributes:
● action

write – the backed up values are copied to the relevant machine data
● id
