Use complex variables
18528
There are different complex variables (STRUCT) at the programmer's disposal. They bundle logically
associated data sets. Thereby, they facilitate the organisation of the data storage in the application
and at the same time reduce the error rate when variables are declared.
The following complex variables are available:
Name Description Reference
ASI_NET The complex variable contains the complete process image
(inputs and outputs) of an AS-i network.
→ ASI_NET (STRUCT)
(
→ p.
117 )
ASI_DATA The complex variable contains the following components:

Slave lists (LPS, LDS, LAS, LPF, LCE, LCEMS, LCEAS,
LDAE)

Parameter images (PI, PP)

Configuration data of the AS-i slaves (CDI, PCD)
→ ASI_DATA (STRUCT)
(
→ p.

→ Get_ASi_Data
(
→ p.
