11.1 Error Classes and Module Responses
The FM 453 contains monitoring circuits which are active during startup or
during continuous operation. Errors occurring during those times are reported
to the system and to the user program.
The table below lists the error classes and their meaning.
Table 11-1 Error Classes, Overview
Message Error Class Response Significance
Internal errors
...are hardware faults in the module which are discovered by diag-
nostics routines (e.g. memory errors).
(See Section 6.4 for diagnostic interrupt data and error list, Table
11-4)
Diagnostic
interrupt
External errors
Everything
OFF
... are errors which can occur due to faulty module connection (e.g.
front panel connector missing).
(See Section 6.4 for diagnostic interrupt data and error list, Table
11-4)
External
channel errors
...are measurement system errors or errors which can occur by
connecting the digital outputs or during operation (operating
errors) of the FM 453 (e.g. cable break, incremental value
encoder).
(See Section 6.4 for diagnostic interrupt data and error list, Table
11-4 and 11-5)
Checkback
signals
Operator control
and travel errors
Feed STOP
... are errors (general operator control and guidance errors) which
can occur during “operation” of the FM 453 (e.g. direction signals
R+ and R– set at the same time, see Error List, Tables 11-6 and
11-7).
signals
Data errors Warning!
... are errors (data, machine data and traversing program errors)
which are detected on interpretation of invalid data (see Error List,
Table 11-8).
Each error message triggers an appropriate response.
