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