6.22 SVC_REQ 21: User-Defined Fault Logging
Use SVC_REQ 21 to define a fault that can be displayed in the Controller Fault Table. The fault
contains binary information or an ASCII message. The user-defined fault codes start at 0 hex.
The error code information for the fault must be within the range 0 to 2047 for an
Application Msg : to
be displayed. If the error code is in the range 81 to 112 decimal, the CPU sets a fault bit of the same
number in %SA system memory. This allows up to 32 bits to be individually set.
Error Code Status Bit
Errors 0 — 80 No bit set
Errors 81 — 112 Sets %SA
Errors 113 — 2047 No bit set
Errors 2048 — 32,767 Reserved
When EN is active, the fault data array referenced by IN is logged as a fault to the Controller Fault
Table. If EN is not enabled, the ok bit is cleared. If the error code is out of range, the ok bit is cleared
and the fault will not be logged as requested.
The parameter block is an input parameter block only with this format:
Parameter address
Error code
MSB LSB
1 Text2 Text1
2 Text4 Text3
3 Text6 Text5
4 Text8 Text7
5 Text10 Text9
6 Text12 Text11
7 Text14 Text13
8 Text16 Text15
9 Text18 Text17
10 Text20 Text19
11 Text22 Text21
12 Text24 Text23
The input parameter data allows you to select an error code in the range 0 to 2047 and text
information that will be placed in the fault extra data portion of a long controller fault. The controller
fault address, fault group, and fault action are filled in by the function block.
