Mounting the Chassis on a DIN Rail Use the NI 9915 DIN rail mount kit if you want to mount the chassis on a DIN rail. You need one clip for mounting the chassis on a standard 35 mm DIN rail. Complete the following steps to mount the chassis on a DIN rail: 1. Fasten the DIN rail clip to the chassis using a number 2 Phillips screwdriver and two M4 × 16 screws. National Instruments provides these screws with the DIN rail mount kit. Figure 7. Installing the DIN Rail Clip on the NI 9144 Chassis

3. Press down firmly on the chassis to compress the spring until the clip locks in place on the DIN rail. Caution Remove any C Series I/O modules from the chassis before removing the chassis from the DIN rail. Connecting the NI 9144 Chassis to a Network NI recommends that you install a private network segment for your deterministic Ethernet expansion devices. Slave devices cause network flooding on a standard network. Non-EtherCAT frames jeopardize the system performance and determinism on

Resetting the NI 9144 Network Configuration To reset the NI 9144 network configuration, unplug and replug in the NI 9144 chassis. Safe-State Outputs The NI 9144 has a safe state that lies between its configuration and operational states. When moving out of the operational state down to the configuration state, during normal operation or in case of a serious error, the NI 9144 passes through this safe state. The safe state forces the data of output modules to pre-defined safe values, which a

Using the NI 9144 with an EtherCAT Third-Party Master All of the functionality of the NI C Series modules is available to third-party masters using vendor extensions to the object dictionary. The NI 9144 is a modular device, meaning each module plugged into the backplane has its own object dictionary, and each module configuration is done through this dictionary. If your master software supports AoE services (ADS over EtherCAT), you can address the module directly. If your master software

Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics. Ca

Appendix A Vendor Extensions to the Object Dictionary Most object dictionary entries are defined by the relevant EtherCAT and CANOpen specification for modular slave devices. Both the NI 9144 device and the C Series modules have vendor extensions to the standard. These extensions are described here. Note Most object dictionary entries are set to usable defaults during the NI 9144’s transition from INIT to PREOP. NI recommends writing down the object dictionary default values, in case you ne
