Chapter 2 Installing Compact FieldPoint Hardware and Software Connecting the cFP-21xx to a Network Connect the cFP-21xx controller to an Ethernet network using the RJ-45 Ethernet port on the module. Use a standard Category 5 Ethernet cable to connect the cFP-21xx to an Ethernet hub, or use an Ethernet crossover cable to connect the module directly to a computer.
Chapter 2 Installing Compact FieldPoint Hardware and Software If you have already assigned an IP address to the cFP-21xx, the STATUS LED turns off, the I/O module READY LEDs come on, and the cFP-21xx is ready for use. The total boot time for a configured system is 15–20 seconds.
(the watchdog state). The network watchdog is disabled by default. Note National Instruments recommends leaving the network watchdog disabled when you are running embedded applications on the cFP-21xx. Refer to the section of this chapter for information about the hardware watchdog for embedded applications.
Chapter 3 Feature Descriptions Storing a Custom Power-Up Configuration Setting a Power-Up State with the Snapshot Feature The Snapshot feature stores the current state of the Compact FieldPoint hardware for use as the power-up state of the system. Caution Using the Snapshot feature overwrites any power-up values you have specified for individual channels.
Chapter 3 Feature Descriptions 100 Mbps LED The green 100 Mbps LED is lit when the cFP-21xx is communicating at 100 megabits per second. If the 100 Mbps LED is not lit, the cFP-21xx is communicating at 10 megabits per second. User-Configurable LEDs A–D LEDs B, C, and D can be sent values of 0, 1, or 2.
Chapter 3 Feature Descriptions CONSOLE OUT Switch With a serial-port terminal program, you can use the Console Out switch to read the IP address and BIOS version of the controller. Connect the serial port on the controller to a computer. Push the switch to the ON position. Make sure that the serial-port terminal program is configured to the following settings: •...
Chapter 3 Feature Descriptions Table 3-2. DB-9 Pin Descriptions (Continued) DB-9 Pin RS-232 Signal COM 2 (cFP-2110 and cFP-2120 Only) COM 2 is an RS-232 DTE serial port with a 10-position modular jack. The Serial Port VIs access COM 2 as port 1. Refer to Figure 3-3 and Table 3-3 for pin locations and signal descriptions.
Chapter 3 Feature Descriptions COM 4 is designed to operate in four-wire mode as shown in Figure 3-4. You can use COM 4 in two-wire mode, but you must design your application so that it filters out the writes that echo back over the read channels.
Chapter 3 Feature Descriptions File Transfer Capability When running on a cFP-21xx, the Real-Time Engine has a File Transfer Protocol (FTP) server. The FTP server gives you the ability to use any standard FTP utility for transferring files to and from the hard drive of the cFP-21xx.

Chapter 4 LabVIEW Real-Time Programming LabVIEW Real-Time applications that have any of the unsupported functionality previously listed may or may not work as expected on the cFP-21xx. Complete the following steps on the host PC to target LabVIEW Real-Time to the cFP-21xx: Start LabVIEW.
Chapter 4 LabVIEW Real-Time Programming RT Target: Access Use RT Target: Access options to limit which host PCs can target the Real-Time Engine on the cFP-21xx. Complete the following steps to open the RT Target: Access dialog box: Target LabVIEW Real-Time to the cFP-21xx. Refer to the Targeting LabVIEW Real-Time to the cFP-21xx section for more information.
Chapter 4 LabVIEW Real-Time Programming The default RT Target: Access settings permit any host machine to target the Real-Time Engine on the cFP-21xx without a password. Note If the cFP-21xx does not have access to a Domain Name Server (DNS), do not use domain name entries in the RT Target Access List.
