Diagnostic display on the 8-position
A24V-/0.5A-IB output module
The IB DIA and D0-D7 diagnostic LED on the 8-position output
module show the diagnostic messages listed in the table below.
This supplements the diagnostic display on the bus coupler and
more precisely defines the cause of the error. The S1/2 must be
activated with IB DIA.
