Diagnostics on the host controller

All the diagnostics information is also provided on the host controller.
7.2.1

Diagnostics through process data

Diagnostics through the process data provides a very simple means of incorpo-
rating diagnostics information into the controller program and displaying it on a
control panel.
For useful diagnostics we recommend use of the following modules:
7.2.1.1

Diagnosing the AS-i circuits


Device parameter and diagnostic data (see chap. 6.2).
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.
7.2.1.2

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 diag-
nostics information for a safety AS-i output the associated diagnostics slave
address must be incorporated (see par. <A>).

Safety Control/Status
Diagnosing the states of the release circuits (see chap. 6.1.4)

Monitor and I/O Data
Status of the safety monitor and of the local safety in- and outputs (see
chap. 6.1.5)

Fieldbus bits
Manufacturer specific diagnostics (see chap. 6.1.3)

Diagnostics Safe Link
In case safe coupling of multiple safety monitors is used via Safe Link (see
chap. 6.1.6).
