Array of Bool and Word with AT command

Hi,

I have Tia 13sp1. I can not put the AT command to static cell. How can I do that?

Thanks.

Hi.

Choose non-optimised data structure.. this is the easiest way.

For optimised structure please review the instructions given in the image.

If this is still not helpful.. show us what you have and what you want to do by including a screen capture.

I cannot  put        Alarms_1      AT "AlarmBits_1"  in one cell.

I set retain to Set in IDB. the FB block is optimized.

How?

Hi Martin,

Thanks for the picture...
getting the AT function to work properly is a bit tricky (counter intuitive).
See the FAQ first [LINK].

What it boils down to -
* type the variable (AlarmBits) with the WORD (as you have done)

* type the overlay variable.. but first as a normal ARRAY (forget the at for now)

* with the variable (Alarm) declared as a normal variable... now type "AT" instead of the "ARRAY" type decleration.

LATE NOTE:
Be careful which variable is the overlay variable. The one that contains the AT cannot be read outside the local FB / FC. Personally I have the array as the primary variable and pass the WORD over to the HMI through another variable on the OUT parameter.

Step A (all as normal variables.. ignore #edge)

Step B (type AT instead of WORD)

Step C (after pressing [enter])

New question published by AutoGen_8968932 is split to a separate thread with the subject Is there an easy way to allocate the booleans from a DB into the bits of a word which belongs to a DB (array of words)? .
