    You can also mount the NI 9144 in other orientations, on a nonmetallic surface, on a 35-mm DIN rail, on a desktop, or in a rack. Mounting the NI 9144 in these or other configurations can reduce the maximum allowable ambient temperature and can affect the typical accuracy of modules in the NI 9144.

    AoE protocol allows you to specify the destination port or address of the SDO request. An address of 0 indicates the NI 9144. Addresses 1 through 8 route the SDO request to the object dictionary of the module in the addressed slot. If no module is installed in the addressed slot,...

  • Page 18: Using Coe/Sdo

    After the module-specific SDOInfo and SDO requests are complete, the application writes 0 to the module object dictionary index 0x5FFF, subindex 0 to return control to the NI 9144 main object dictionary. Vendor Extensions to the Object Dictionary Most object dictionary entries are defined by the EtherCAT and CANOpen specifications for modular slave devices.
