String Array Data Type

Ignition
1

Hello Everyone,

I have a simple question, but I'm having a hard time understanding how to use a String Array. I couldn’t find any information about this in the user manual or here in the forum.

In my PLC, I have a UDDT that includes a String[21] data type. I want to create a similar string array in Ignition, but when I try to define String[21] in the data type, it doesn’t work. Also tried the parameter binding and I wasn't susccessful.

Any guidance would be greatly appreciated!

It might help to mention the PLC make and model and the OPC driver you're using to connect to it.

I am using a ControlLogix PLC (1756-L81E, 5580 Controller) and Allen-Bradley Logix OPC Driver

IA's Logix doesn't support addressing arrays as arrays. My alternate driver does support it, but only for arrays of numbers, not strings.

I see, thank you for the information, then I am going to have to create a string tag for each of those tags then.
