I would like to switch the polarity of an OPC float value. The convers doesn't allow negative values. It seems simple but I haven't found the answer.

Gregor.Beck​, thank you for your reply.

I haven't tried anything else. I was looking over this table and didn't see anything relevant to try.

It's very common for to get a KW value from a transformer that is a negative value when a site is producing because the meter is looking at the value from the grid's perspective. We work from the site's perspective and want to see the value as positive when the site is producing power. It is a very common need for us and I was expecting the conversion would be more common than it apparently is.

This is the table I was trying to work from.

Do you have any suggestions of conversions to try?

Thanks
