5.5 Evaluation and acknowledgment of module-spe-
cific diagnostic messages
Depending on the error type, errors that are diagnosed in the Inline PROFIsafe modules
from Phoenix Contact used are transmitted to the RFC 4072S as diagnostic messages
using PROFINET.
Phoenix Contact provides special function blocks for device-specific diagnostics for the
Inline and Axioline backplane bus systems. These function blocks enable global or local
device-specific diagnostics.
On the one hand, the AsynCom_PN_Info function block from the AsynCom_V1_06_610200
library must be used for this purpose. This function block is used for reading information of
the connected PROFINET devices. The function block receives this information from the
configuration of the RFC 4072S (device IDs, PROFINET names, etc.).
On the other hand, function blocks from the PN_Dev_Diag_V1_13 library must be used. An
example of device-specific PROFIsafe diagnostics is the PNFD_IL_Diag function block.
This function block is used for diagnostics of a safety-related device of the Inline product
range via the PROFIsafe address. Displayed diagnostic messages can be confirmed
(acknowledged) with the help of the function block.
5.5.1 AsynCom_PN_Info_V1_01 function block
Function block for reading information of the connected PROFINET devices.

The product documentation for the modules used contains an overview of the diagnosed
errors, their causes, effects, and possible measures for error removal, as well as informa-
tion regarding module behavior following acknowledgment of diagnostic messages.
• For every error that occurs, the cause of the error must first be removed. If necessary,
the error is then acknowledged.
