Controlling a Heating Element
Tip If you autoconfigured your FP-3000, you can skip to the section Set the Output Range .
Create an FP-AO-200 Block
Create an I/O block for the FP-AO-200 channel to control the heating
element. To create an I/O block in the NI-FBUS Configurator, follow these
steps:
1. Right-click on the FP-3000 in the configuration tree.
2. Select Instantiate New Block.
3. Select AO 200 Block from the list, then click on the OK button.
Assign a Tag to the New Block
By default, new blocks are created without a tag. To assign a tag, follow
these steps:
1. Right-click on the new block, then select Set Tag.
2. Enter the tag you choose in the dialog box. The tag can be up to
32 characters in length and should not contain the dot (“.”) character.
3. Make sure Set to OOS Mode is checked.
4. Click on Set.
Select the Module and Channel
1. Double-click on the new block. In the block configuration window that
appears, select the I/O Config tab.
2. Determine the FP-AO-200 module number by counting each module
in the order it is attached to the FP-3000, beginning with one. In this
example, your FP-TC-120 is probably the only module connected to
the FP-3000, and the FP-AO-200 is probably the second module.
Therefore, set the value of
FIELDPOINT_MODULE to Module 2 .
3. Since the transmitter is wired to the terminals associated with channel
zero on the module, set the
FIELDPOINT_CHANNEL parameter to
Channel 0 .
Set the Output Range
1. Click on the FP_AO_200_RANGE parameter on the I/O Config tab in
the block configuration window.
2. Set the parameter to a current range of 0–21 mA .
