8 AOI Support:

Devices with a large number of parameters, or with multiple Boolean parameter functions in a single byte, can become difficult to manage. Therefore, a device specific AOI can improve the user experience when using the

Mailbox Function.

Attached there is an example AOI which demonstrates the use of the mailbox with a 3 rd

party RFID reader.

There are two separate AOI’s, read parameters and write parameters.

8.1 Read Parameters of RFID Reader

Import the attached AOI into the Rockwell project.

Figure 8.1

Precede the Read MSG instruction with the AOI. In this case, use the same trigger as the MSG instruction. You should notice the tags for Source and Destination are the same tags used in the MSG instruction.

Figure 8.2

A new tag must be created for “Parameter Read Values”. This will be of user defined data-type:

“UDT_FESTO_RFID_BISM_4x_Param_RDWR” which comes from the AOI installation.

Note

By reviewing tag names below, please note:

• The tag name RFID_Param_CTEU data-type is user defined from the AOI

• There is one function, to select the index to read. These are values 1 to 7, defined by the AOI, and described in the comment field

• In this example, value 3 ( Act on Tag) is selected

• The AOI automatically loaded the index + sub-index with the proper values to the tag

RFID_RD_source_CTEU

• When the trigger was enabled, the BIS 4xx returned a 7, meaning AUTO 8 bytes

• The value is stored in the tag RFID_RD_destination_CTEU

• It is also copied to the tag RFID_RD_Param_CTEU, so the user only needs to reference this tag name
