Addition to trending...

The trend graphic element now supports "limits" and "banding".

Limits are static lines that can be used to display an alarm level, setpoint value, etc..

Banding can be used to display a range.

Any number of limits or bands can be added to the trend.

HMI update 9/13/2012...

Today we released a new version of the HMI with support for Toshiba computer link protocol for UDP/IP. The previous release was for RS-232/485. The same register types and data types as RS-232/485 are supported.

The HMI now has the ability to change the tagname of a trend pen at runtime. One or all pens can be changed with one command.
