It is also possible to renumber FB239 (DELETE)
•
in DB1 (see Section 11.3) or
•
By changing system data word 202 in the RESTART OB (OB21 or OB22) using the "T RS 202"
operation. System data word 202 must not be changed using the "DISPL. ADDR.", "TNB",
"TIR" or "TDI" operations!
Example:
The integral FB239 (DELETE) is to receive the number 53. Make sure that FB number 53 has not
already been assigned to another FB (if a user program FB has the same number as the integral
FB "DELETE", the "old" FB number is retained in system data word 202).
The number of integral FB238, which can also be changed by system data word 202, should be
retained!

No error
No such block
Invalid block type specified in the TYPE parameter
Block exists, but has an EPROM identifier
DELETE function cannot execute because another function is in
progress (e.g. a programmer function)
Low-order byte
(Number of FB "DELETE")
+239
+53
FB4 is called by OB21 and OB22.
The numbers of FBs COMPR and DELETE are
transferred to system data word 202.
Read RS 202 (check if new number has been
accepted)
If not ... STOP!
