3.1 Overview of diagnostic possibilities
The following possibilities for diagnosis and error handling
are available, depending on the configuration:
Diagnostic
option
Brief description Advantages Detailed
description
LED display The LEDs directly show
configuration faults, hard−
ware faults, bus faults, etc.
Fast on−the−spot"
recognition of faults
Section 3.2
Status bits Internal inputs which supply
coded common diagnostic
messages.
The 8 status bits are trans
mitted to the module as
inputs" cyclically with the
normal inputs.
Fast access to fault
messages in the PLC user
program, irrespective of
the module and master
Section 3.3
I/O diagnostic
interface
Bus−independent diagnostic
interface at I/O level which
enables access to the internal
data of the CPX terminal
(16inputs and 16 outputs)
Read access to internal
parameters and data at
I/Olevel
CPX system
description
Diagnostics via
the handheld
unit
Diagnostic information can be
shown on the handheld unit
in a user−friendly manner by
means of menus.
Fast on−the−spot"
recognition of faults
without programming in
clear text

Diagnosis via
PROFIBUS−DP
Diagnosis as per PROFIBUS
standard
Detailed module−related
and channel−related fault
recognition in the online
mode of the programming/
configuration software and
in the PLC user program
Section 3.5
Diagnosis via
PROFIBUS DPV1
Access to all system data of
the CPX terminal via the field
bus
Extended access to
diagnostic data in the
PLCuser program
(e.g. diagnostic memory)
