General Information

The parameters explained in this document are characterized by parameter types. The following table provides information on the different parameter types:

Type	Offline editable	Properties	Read value	Write value
ER	X	Input with user initialization Transfer only after reset	Quick memory access	Not used, as transfer takes place only after reset
ED	X	Input with user initialization Transfer directly after the modification	Quick memory access	Quick memory access
ED		Input with automatic initialization to default value Transfer directly after the modification Can only be modified online by the Logic Builder	Quick memory access	Quick memory access
EF	X	Input with user initialization Transfer directly after the modification	Quick memory access	Functional access (internal calculation required)
EF		Input with automatic initialization Transfer directly after the modification	Quick memory access	Functional access (internal calculation required)
ES		Input Transfer directly after the modification Can only be modified online by the Logic Builder	Quick memory access	Communication via Sercos Delay of the caller (typically 10-100 ms)
AK		Output Constant value	Quick memory access	Not possible
AD		Output Dynamic value	Quick memory access	Not possible
AF		Output Dynamic value	Functional access (internal calculation required)	Not possible
AS		Output Dynamic value	Communication via Sercos Delay of the caller (typically 10...100 ms)	Not possible
If the parameter is displayed in the Logic Builder in a black font, it is editable offline. If it is displayed in a gray font, it is only editable online.

NOTE: In the case of parameters read or written via Sercos, the typical time delay is 10...100 ms. However, this value can be delayed by 100 ms or more, for example, when using trace logging or Error Quit trace logging or Error Quit.
Tracing these parameters causes a delay of the trace task.
