Openplant String.Replace Function

Hello Vivek,

Thanks for posting your query on plant forum.

Can you please confirm on which data type property you are using this custom attribute? Is it double or string?

Also, what the exact requirement here, where you want to use System.String.Replace

It would be great if you can log service request on this issue.

Thanks, Deepak,

system.string are always for string datatypes, i would like to change part of component description, with this ec expression.

if a ticket is required, i could create it, i thought it was quick fix.

Hello Vivek,

I have posted a document I created that contains several examples using System.String (Others too). It can be found in the Files - OpenPlant folder in this Community. These were used in OpenPlant PID. These should work in OpenPlant Modeler as well.

Hello Vivek,

I have tested this, and currently we do not support System.String.Replace.

What i suggest is to use a secondary property IE DESCRIPTION_ENTRY. Then, on the DESCRIPTION property, make the ECExpression an IIF statement.

So...

DESCRIPTION Property ECExpression:

IIF(this.DESCRIPTION_ENTRY="304","10","")

To protect the DESCRIPTION property, you could make it read only. The users would then enter the "description value" in the DESCRIPTION_ENTRY property, and this would drive the value published in the DESCRIPTION property.

With the IIF statement, you can also offer up several values:

IIF(this.DESCRIPTION_ENTRY="304","10","") & IIF(this.DESCRIPTION_ENTRY="404","20","").

I hope this helps,
