Error identifiers
If it was not possible to execute a job, the failure is indicated by "logic 1" on status parameter
error. The error cause is coded at the block output State:
State Meaning Note
WORD H WORD L
0 1 Access error
0 2 Error in job Incorrect compilation of Var. in a job
0 3 Negative
acknowledgment, job not
executable
Internal error, any help:
NC RESET
0 4 Data areas or data
types do not tally
Check data to be
read in RD
0 6 FIFO full Job must be repeated,
since queue is full
0 7 Option not set BP parameter "NCKomm" is not set
0 8 Incorrect target area (SD) RD may not be local data
0 9 Transmission occupied Job must be repeated
0 10 Error in addressing Unit contains value 0
0 11 Address of variable
invalid
Check Addr (or variable name), area,
unit
Configuration steps
To be able to read a GUD variable, its name must be stored in a string variable. The data
block with this string variable must be defined in the symbol table so that the "Addr"
parameter can be assigned symbolically for FB GETGUD. A structure variable can be
defined optionally in any data area of the PLC to receive the variable pointer (see
specification in following example).
