abSl_diag[16] / Slave diagnostic area
This variable is a field of 16 bytes containing the diagnostic bit of each slave. The following
table shows the relationship between the slave station address and the corresponding bit in
the variable abSl_diag.
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 89).
'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.
Address of slave with the diagnostics request
This byte contains the master address of the ILX69-PBM which has
done the parameterization of the slave. If a slave is not
parameterized, the value is 255.
PROFIBUS Identification number from slave in which the
diagnostics request was made.
