Can VIewON Graphing display decimals?

[nickTriPhase1]

Can the viewON trend graph easily graph decimal numbers as they come in from Modbus or other sources?

I’ve heard that decimal numbers are not possible on the trend graph and wanted to get more info.

Thanks!

I shifted this into its own question as it seemed like it would make more sense as a full topic.

Yes you can absolutely display decimals in a ViewON trend. This comes down to defining the tags as the proper data types. If you want to show floating points you cannot use AUTOMATIC, INTEGER, or BOOLEAN as the tag type. Only FLOATING POINTS will transfer the proper data type.

The rationale can actually be seen in this other topic of yours:

ViewOn: Can you link up tags before they exist on the eWON

@nickTriPhase1 This is somewhat of a tough one to provide a direct answer to though it is possible to do if you are very careful. With a bit of "hacking’ we can essentially make this work. Now it is important to remember that these values are NOT propagated over to the eWON. They are solely implemented in your ViewOn project for testing. This is an advanced example. Please ensure to proceed with caution. Backup any files that will be altered. Please note, as mentioned above, this is a highly …

ViewON will pull that tag data in as the data type that corresponds to the tag in the eWON. If it is not a float it will not have the ability to show decimals. The below screencap is from our ViewON demo showing live floating points.
