  • Page 4: Purpose

    Based on application requirements, the CDN366 can integrate with many brands of PLC (AB, Omron, etc.) or PC based platforms (Synergetic, etc.). As long as a DeviceNet network is available for a particular application, the CDN366 should be able to integrate in the network.

  • Page 5: Schematic Diagrams

    Schematic Diagrams: The electrical schematic diagram figure 1 shown on page 3, CDN366 is integrated with an Allen Bradley (AB) SLC502. The AB SLC500 four-slot rack system contains a rack power supply (1747-P1), a PLC processor on slot 0 (1747-L524), and a DeviceNet scanner module on slot 1 (1747-SDN), an 8 points input module on slot 2 (1746-IV8), and an 8 points output module on slot 3 (1747-OB8).

    CDN366 Setup & Configurations: Prior to the setup and configuration of the CDN366 device, the PLC hardware (power supply, CPU, DeviceNet scanner, I/O modules), software (RSLinx, RSNetWorx & RSLogic500) and interface modules must be setup and configured first. (For further information on setup and configuration of the Allen Bradley PLC controller, please visit www.ab.com)

  • Page 16: Change Parameter Setting Using Rsnetworx

    Change Parameter Setting Using RSNetWorx: The CDN366 must be offline (not on Scanlist) to change any parameters. Some of the parameters cannot be change, but can be read (see CDN366 DeviceNet Specifications for details). Before making the parameter change, always upload the current parameters from the CDN366 device.

    5) Flow Control: The flow control can be set at 0, 1, or 2. When flow control is set to 1, the X-Off (CTRL S) will force the CDN366’s transmit function to block. The transmitted characters are stored in the FIFO buffer until transmission is re- enable by sending the X-On (CTRL Q) character to the CDN366.

  • Page 19 Length – When a value (byte range from 1~255) is set in the Packet Length, (Class=64, Instance=1, Attribute=14) the data packet is fixed based upon the Packet Length. As the data packet receives from a poll response, the data packet is complete as number of bytes sent is equal to the byte value set in Packet Length.

    Serial Receive Object Parameters (Class Code 65): There are eight identical receive (Rx) instance parameters which can be set in CDN366. This section will review one of the eight receive instance parameters. These parameters can easily be changed using RSNetWorx. When using RSNetWorx to upload the parameters, first go to “Groups”...
