Re: [foxboro] block alarm ack. from IND block

Alarms are acknowledged by resetting (setting to 0) the .UNACK of the block 
with the alarm.
You can change that from HLBL by using an external reference:

:C:B.UNACK := FALSE;

Make sense?

Subject: [foxboro] block alarm ack. from IND block
 
Hi list,
 

I'm looking for a way to acknowledge an alarm (i.e. comp:block.HHAIND
from a AIN) from an IND block.

The AIN block doesn't have an "ack" input and I can't find the right
HLBL instruction.

I was looking in the HLBL user guide B0400DF.

Are there any other manuals available concerning HLBL instructions?

 

Thanks in advance,

 

Met vriendelijke groet / Best regards,
