8 Function libraries
For configuring the PROFIBUS and for diagnostic purposes, the following function libraries are
available in the »PLC Designer«:
• CAA_Device_Diagnosis.lib
• IIoDrvDPV1C1.lib
8.1 CAA_Device_Diagnosis.lib function library
This library serves to query diagnostics information from the PROFIBUS master and the slaves.
8.2 IIoDrvDPV1C1.lib function library
The IIoDrvDPV1C1.lib function library supports the acyclic PROFIBUS DP-V1 - class 1 writing and
reading services for data transmission between the master and the slaves. The data are addressed
via slot and index within the slave nodes (see PROFIBUS-DP standard).
Codes or indexes can be read or written with the IoDrvDPV1_C1_M_Write and
IoDrvDPV1_C1_M_Read functions via DP-V1.

Note!
The diagnostics information in the CAA_Device_Diagnosis.lib function library is
currently only partly available. You can only execute a diagnostics process if the node
works without errors or if there is a fault. Currently, the PLC does not provide any
detailed fault information.
