Studio 5000 - How to Increase the LEN of string

[SSrikakolum]

I want  increase the length of string from 82 to 150. By default it comes 82 is it possible to do so in Studio 5000

You cannot change the capacity of the built-in STRING datatype, but you can create your own string datatypes.  You get to choose the capacity for those.  Anywhere in your own UDTs or AOIs, you can use any alternate string type you need.

Hello @pturmel I created a Datatype Strings with length 150 but when i used it , it says few errors. I am not sure why I work more on Omron PLCs so have not got much experience with studio5000 . i have attached screeshots can you please tell me what are they and what they mean?

Also this program was created by someone else. 

I am using the created strings for different Tag but why is it affecting DataType ALARM_DIGITAL TAGS?

ERR : BASE TAG IS NOT VERIFIED

ERR : ASSOCIATED TAG MUST BE A BOOL, SINT, DINT,LINT OR STRING DATA TYPE

ERR : TAG DOESN'T REFRENCE VALID OBJECT OR TARGET

@SSrikakolum The data type is strings. Change the data type to string and see if it works.

Hi paul the data type was string earlier. with len [82] which wasn't sufficient, so i created new string called strings and assigned the new data type. Then this happened. If I do it to string back again there is no Errors then.

Thank You

To use the new "STRINGS" datatype in place of "STRING", you have to change the definitions of the tags and other data types that are using "STRING".  For any built-in data types, like ALARM_DIGITAL, you cannot do this, and you cannot use longer strings.  Sorry.

You have to create a new string data type with a name different from STRING.  Attempts to change the built-in string will break things.
