Taking Temperature Readings
Tip If you autoconfigured your FP-3000, you can skip to the section Set the Input Range
and Thermocouple Type .
Create an FP-TC-120 Block
Once the hardware for control loop has been installed, you need to
instantiate, or create, an I/O block for the thermocouple input channel. To
instantiate 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 TC 120 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-TC-120 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. Therefore, set the value of
FIELDPOINT_MODULE to
Module 1 .
3. Since the transmitter is wired to the terminals associated with channel
zero on the module, set the
FIELDPOINT_CHANNEL parameter to
Channel 0 .
