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.
