DX0-FE (DX 0 or DX 2
Errors)
Note
DX 0 and DX 2 errors have a common control bit (DX0-FE) in
the control bit screen form.
Errors evaluating data block
DX 0
In the event of a DX 0 error you will find error identifiers in the
system data words RS 3 and RS 4 that define the error in more detail.
Error identifier
RS 3 RS 4
Explanation
0431H yyyyH Illegal identifier:
- header identifier missing or incorrect
(correct KC MASKX0)
- field identifier illegal
- end identifier missing or incorrect (correct
KH EEEE)
yyyy = illegal identifier
0432H yyyyH Illegal parameter
yyyy = illegal parameter
0434H yyyyH Illegal number of timers (permitted: 0...256)
yyyy = incorrect number of timers
0435H yyyyH Illegal cycle time monitoring (permitted: 1 ms
to 13000 ms)
yyyy = incorrect time value
Errors evaluating data block
DX 2
Parameter assignment for the second serial interface.
Data block DX 2 is set up by the system program after a COLD
RESTART. In the event of a DX 2 error, you will find error identifiers
in the system data words RS 3 and RS 4 that define the error in more
detail.
Error identifier
RS 3 RS 4
Explanation
0451H — DX 2 length (without block header) < 4 words
is not permitted
0452H yyyyH DX 2 length (without block header) is too
short for link type
yyyy = length DX 2
