VIRTUAL CHANNELS CONFIGURATION<br />
The following screen allows the configuration of the virtual channels. Each virtual channel is the result of a mathematical<br />
or logical operation and must be configured by selecting a unique tag (name - maximum of 16 characters) for this<br />
channel. You should then select the first channel that will serve as the operand (depending on the selected operation, it<br />
will be the only one). When you select "Constant Value", you will be able to assign a numeric value to the virtual channel<br />
(this value can be used as an operand in other virtual channels). After that, you must choose the operation to be<br />
performed and which channel is to be used as the second operand in the operation (when previously chosen "Constant<br />
Value", there should be placed the numeric value of the channel).<br />
Finally, one should choose a unit (optional - maximum of 10 characters) for the channel, plus an error value and the<br />
number of decimal places desired in the indication of the same one. When clicking on "Add", the newly configured<br />
channel is added to the list of virtual channels.<br />
When a virtual channel is configured, all enabled input channels are available for use as operands, including virtual<br />
channels already placed in the list. This enables us to generate relatively complex expressions, using the result of an<br />
operation as an operand in another one. For more details, please see the section "Virtual Channels" under the chapter<br />
"<strong>Field</strong><strong>Logger</strong> Operation”.<br />
Clicking on any virtual channel in the list, its parameters are loaded at the top fields. To delete a channel, you must select<br />
it from the list and click on "Remove". To delete all the virtual channels, you must click on "Remove All".<br />
