6.1 Response to the system error
In principle, the programmer is responsible to react to the error flags (system flags) in the application
program.
The specific error bits and bytes should be processed in the application program. An error description
is provided via the error flag. These error bits/bytes can be further processed if necessary.
In principle, all error flags must be reset by the application program. Without explicit reset of the error
flags the flags remain set with the corresponding effect on the application program.
In case of serious errors the system flag bit ERROR can also be set. At the same time this also has
the effect that the operation LED (if available) lights red, the ERROR output is set to FALSE and the
monitoring relays (if available) are de-energised. So the outputs protected via these relays are
switched off.
6.1.1 Notes on devices with monitoring relay
Only available for the following controllers:
•
ClassicController: CR0020, CR0505
•
ExtendedController: CR0200
•
SafetyController: CR7020, CR7021, CR7200, CR7201, CR7505, CR7506
Using the logic function via the system flag RELAIS or RELAIS_CLAMP_15 (
→
chapter Latching) all
other outputs are also switched off.
Depending on the application it must now be decided whether by resetting the system flag bit ERROR
the relay – and so also the outputs – may be switched on again.
In addition it is also possible to set the system flag bit ERROR as "defined error" by the application
program.
NOTICE
Premature wear of the relay contacts possible.
► Only use this function for a general switch-off of the outputs in case of an "emergency".
► In normal operation switch off the relays only without load!
To do so, first switch off the outputs via the application program!
