AWL :AS instruction

Hi folks,

In a migration S5 to S7-1500, there is the :AS sentence/instruction that I can't find what it does.

 :U   E   32.7

:UN  M   71.1

:UN  T   15

:S   M   71.1

:=   M   80.0

:UN  E   32.6

:U   M   80.0

:=   M   80.0

:AS

:SPB FB 31

What :AS instruction do??

Best Regards,

Pau 

Hello Pau,

AS = disable process alarm

AF = enable proces alarm

Hope this is helpful.

Hello Pau,

The AS and the FB31 have "normally" no dependency, but...

It could be that in the FB31 are controls which dont have any process alarm, e.g. chemical reaction.

You can find the extra information at the manuals of S5.
It's depending of the used CPU, e.g. S5-95U or S5-135U (in my opinion you have a S5-135).
You have different commands which work.

E.g.
