  • Page 7: Optomux Command Summary

    The JDO operates as the DeviceNet front-end to the Optomux B1 brainboards. The DeviceNet Master can receive and send data to and from the 1782-JDO via the methods described in this section. It formats and sends the data to the B1s and accepts responses from the B1, which are reformatted and passed back to the DeviceNet system as required.

  • Page 8: Default Device Configuration

    B1’s are listed in the Parameter list of the JDO. 1.2 Default Device Configuration The 1782-JDO DeviceNet address is read from the switches and is set to 63 and the baud rate is set to Autobaud at the factory. All other parameters are software settable. The default settings for the 1782-JDO are provided in the discussion of the Parameter Object and Table 5-1.
