I am writing batch results back into the database. Via a ControlLogix and SQL server.

I have set up a block data group that reads 32 dints, strings, and reals. The issue is that I do not always need all 32. The data transfers to the server I just end up with a large set of null entries.

Is there a way to only move the parts of the arrays that have data in them?

Thank you,

Hi,

Unfortunately, no. This is a request that comes up from time to time, and something that we will likely implement eventually in Ignition, but currently, the block size is set.

Regards,
