Diagnostics on the host controller

All the diagnostics information is also provided on the host controller.
8.2.1

Diagnostics through process data

Diagnostics through the process data provides a very simple means of incorpora-
ting diagnostics information into the controller program and displaying it on a con-
trol panel.
For useful diagnostics we recommend use of the following options:
8.2.1.1

Diagnosing the AS-i circuits



Flags + Fault Detector (see chap. 6.1.1).

When a configuration error is reported, e.g. because an AS-i slave has failed, the
AS-i master continues to communicate with the remaining slaves. In many cases
however a good and simple solution is to terminate running of the PLC program in
case of a configuration error.
8.2.1.2

Diagnosing the Safety Monitor



Safety diagnostics in the Input Data Image

Diagnostics for the states of the safety AS-i in- and outputs. To obtain diagno-
stics information for a safety AS-i output the associated diagnostics slave
address must be incorporated (see paragraph <A>).


Fieldbus Bits and Safety Status

User-specific diagnosing and diagnosing the states of the release circuits
(see chap. 6.1.4 and chap. 6.1.3)
