CC-Link Gateways
Diagnostics
Important!
The following points must be noted for processing:
•
The information for switching state and error status are not processed time-
synchronous.
•
When there is a configuration error all bits having value 0 are sent; this must
be noted when processing the data.
•
When the Monitor is stopped the device color is "gray".
•
When regularly switching, the status "yellow flashing" can be recognized as a
transition status. This depends on the component model set. This status can-
not be understood as a testing request until it is stably reported (see Monitor
Info and Safety Control/Status Byte). This is not the case until bit '6' is set in
the Monitor Info and Safety Control/Status Byte ("At least one module in Test
status"). This means the diagnostics information in the input data image does
not serve as a trigger for the testing request, but rather only as detailed infor-
mation after the Monitor Info and Safety Control/Status byte have indicated
that at least one component has reported a testing request.
Changing the base setting
Setting and changing the diagnostics type is done using the device display ([SA-
FETY]->[AS-I SAFETY]->[SAFE SUBST VAL])
8.2.2
Diagnosing the safety unit using the command interface
All the diagnostics data can also be queried individually and acyclic using the
command interface commands. This method does however involve greater pro-
gramming effort.
8.2.3
LEDs
The LEDs located on the device allow you to quickly see the status of the main
function parameters, such as power, communication with the host controller, com-
munication on the AS-i circuit and state of the safety in- and outputs.
8.2.4
LC-Display
In the display of the Gateways plain text messages are shown spontaneously for
any detected errors (e.g. missing slaves, earth fault, duplicate address...).
8.2.5
AS-i Monitor
Comprehensive, standard measuring technology built into the AS-i Masters make
it possible to simply localize even sporadically occurring configuration errors and
interference sources affecting AS-i communication.
8.2.5.1
Duplicate address detection
The Master detects when two slaves having the same address are present in the
AS-i circuit.
