5 Next, expand the MVI69PDPMV1.Status.Fieldbus.FB_Slave_Data_xfer tag.

The value for MVI69PDPMV1.Status.Fieldbus.FB_Slave_xfer should match
the corresponding value in
MVI69PDPMV1.Status.Fieldbus.FB_Slave_Cfg_List, indicating that the slave
is configured and communicating.

Tip: You can add ladder logic to perform an action based on the values of these tags, for example
to determine if a slave is misconfigured.

If the values of these tags show that the slave is configured, but is not
transferring data, the slave is not configured correctly. Refer to the
documentation provided with your PROFIBUS Slave for troubleshooting
procedures.
