If the abSl_diag bit of the corresponding slave is logically:
'1' - Latest received slave diagnostic data are available in the internal diagnostic buffer.
This data can be read by the user with a message, as described in section Slave
Diagnostic (page 85).
'0' - Since the last diagnostic buffer read access of the host, no values have been
changed.
Slave Diagnostics Field
Bytes 72 to 79 contain the Slave Diagnostics Field information based on the settings
used to execute this command.
Note: The Slave Diagnostics function can also be executed by CIP message
functionality. Some CompactLogix™ controllers do not support messaging. This
method can be used for controllers that only support I/O or I/O and CIP messaging.
The slave diagnostics only gives the mandatory diagnostics information of a slave.
Extended diagnostics information is received with the CIP message functionality only.
