DBX37.7
Stop at block end is ignored during single block (SBL)
Edge evaluation:
The following machine data and part program commands are used to specify that the stop at block
end during single block (DB21, ... DBX0.4 == 1) is to be ignored:
•
•
•
•
Part program blocks for which stop at block end during single block is ignored are designated as
single block-inoperative.
Signal state 1
Single block is active (DB21, ... DBX0.4==1) AND part program block is single block-inoperative.
Signal state 0
Single block is not active (DB21, ... DBB0.4 == 0) OR
(single block is active (DB21, ... DBX0.4 == 1) AND part program block is single block-operative)
Corresponding to ...
Read-in disable is ignored. DB21, ... DBX37.6 (read-in disable is ignored)

DBB208 - DBB271
Active G function of groups 1 to 60
Edge evaluation: No
Signal state <> 0
A G function or mnemonic identifier of the G group is active.
The active G function can be determined from the value (starting with 1):
1 = 1st G function of the G group
2 = 2nd G function of the G group
3 = 3rd G function of the G group
Please refer to a listing of the possible G-groups with the relevant functions in the Programming
Fundamentals Guide.
Signal state = 0
No G function or G group mnemonic identifier is active.
Application
The active G group is stored in binary code in the relevant byte.
example(s)
The following evaluation applies:
Special cases,
In contrast to auxiliary functions, G functions are not output to the PLC subject to acknowledgement,
errors, ......
i.e. processing of the part program is continued immediately after the G function output.
