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.
