Explanation of the "Ident_Profile" block

All Ident blocks are based on the "Ident_Profile" block. The simplified Ident blocks
run the Ident profile with the suitable parameter interconnection for the respective
RFID functionality. Therefore, the blocks are a simplified interface of the Ident
profile.
Note It is not recommended to work directly with the "Ident_Profile" block if the Ident
blocks can implement the required RFID functionalities.
The Ident profile is based on the standardized "Proxy Ident Function Block"
protocol. For the specification of the protocol, please refer to the PROFIBUS User
Organization (\10\).

Diagnostics and error messages

If an error has occurred, the "STATUS" output parameter of the Ident blocks
provides different hex codes. For the meaning of the codes, please refer to the
"SIMATIC Ident RFID systems Ident profile and Ident blocks, standard function for
Ident systems" manual (\3\), chapter 4 "Error messages".

Block diagnostics in the technology object

The diagnostic function allows you to monitor the devices configured in the
technology object.
Requirements

An online connection has been established between TIA Portal and the
S7 CPU.

The Ident instruction is called in the user program.

A technology object was created and downloaded to the S7 CPU.

The S7 CPU is in "RUN".
Procedure
Proceed as follows to open the display editor for the diagnostic function.
10. In the project tree, open the "Technology objects" folder.
11. In the project tree, open the relevant technology object.
12. Double-click the "Diagnostics" object.
13. Click the "Monitor all" icon to enable monitoring mode.
