Channel Configuration

Use this tab to configure the Spectrum Controls 1734sc-IE2/4CH HART analog input channels.

On this tab, you can:

select the channel you want to configure

enable HART communication

view input range type

select a digital filter time

select scaling

Tip
: The module’s configuration information is stored in the controller and the controller configures the module.

Note
: The 1734sc-IE2/4CH Owner’s Guide, which is available online by following the hyperlink on the Vendor tab, provides additional configuration information for some of the parameters discussed in this help file.

Channel

Click one of the channel buttons to display its information on this tab.

Enable HART Communication checkbox

Enables HART communication for the selected channel.

Range Type

Select the channel's input range within 3.42 mA to 20.58 mA

Scaling

Low Engineering

Enter a value in user engineering units to which the Low Signal should be scaled. All values sent to/from the module are in engineering units.

High Engineering

Enter a value in user engineering units to which the High Signal should be scaled. All values sent to/from the module are in engineering units.

Digital Filter

Select a filter time constant for this channel. A non-zero value enables the filter, providing a time constant in milliseconds used in a first order lag filter to smooth the input signal. If non-zero, must be greater than twice the Update Rate. Range is 0 to 20100 ms.

If:

you are online in Program, Remote Program or Remote Run mode and,

this controller is the owner controller and,

you have changed the module’s configuration in the software, when you click the Apply or the OK button, the information is automatically sent to the controller. The controller tries to send the information to the module (if the module’s connection is not inhibited). If you don’t click Apply, your changes are not sent to the controller.
