Slave Diagnostics Field
The Slave Diagnostics array is an array of 8 bytes which includes slave diagnostic
information based on the settings used to execute this command. The definition of this array
and its indications are shown in the Following table.
Note: The same Slave Diagnostic function can also be executed by CIP message functionality described later in
this manual. Some types of the CompactLogix controller family do not support messaging. This method below
can be used for controllers that only support I/O or I/O and CIP messaging. The slave diagnostic via I/O has the
limitation that it cannot show extended diagnostic information, if a slave supports this. It can only give the
mandatory diagnostic information of a slave. Extended diagnostic information can be received with the CIP
message functionality only.
