    Supplement The communications function is used by creating a program on the host com- puter. As such, the explanations in this chapter are from the perspective of the host computer. For example, “Read/Write” refers to the host computer reading or writing to the K3HB.
  • Page 24 After a receiving a response from the Digital Indicator, have the host computer wait at least 50 ms before sending the next command. When writing multiple sets of setting data in a row, such as when writing to the variable area or performing a compound write, controllability may be affected.
  • Page 25 • Use terminals B1 through B3 to communicate with the host. • Wiring is configured 1:1. • The maximum cable length is 15 m. Use OMRON’s Z3RN RS-232C Opti- cal Interface to extend the wiring path. • Use shielded, twisted-pair wires of at least AWG28 to AWG16 for all cables.

    SP has already been set. If the Output Enable Bits are set to 1 and then set to 0, no SP will be writ- ten even if one is accidentally allocated. (However, care must be taken because writing is enabled if Output Enable Bits are set to 1.)

    Lower byte Related information Bit 15 is strobe 2 and bit 14 is strobe 1. A logical OR is taken between the two leftmost bits of the command code and bits 15 and 14, and the result is attached as the strobe to the operation command. The command code for K3HB-DRT operation commands is 0@ hex, so when the logical OR is 8@ hex, the strobe is ON.

    The Attribute ID does not need to be specified for some commands. Data Specifies the details of the commands, set values, etc. The data section is not required for read commands. Response Block The following format is used when a normal response is returned for the sent explicit message.

    (bit 07) turned ON is returned. (For example, when the service code of the command is 0E hex, the service code of the response will be 8E hex.) When an error response is returned for the explicit message, the service code is always 94 hex.

  • Page 100: Compoway/F Binary Commands

    CompoWay/F Binary Commands CompoWay/F binary commands use hexadecimal values for the CompoWay/ F frames, and not ASCII. Therefore, the data volume is about half of Compo- Way/F ASCII commands. The following restrictions apply. • Read Controller Attribute (05 03), which includes ASCII in the Compo- Way/F frame, cannot be used.

    • Wipe the Digital Indicator with a dry, soft cloth for regular cleaning. • When dust or dirt cannot be removed with a dry cloth, dampen the cloth with a neutral cleanser (2%), wring out the cloth, and wipe the Digital Indi- cator.
  • Page 115 Replacing Digital Indicators The Network consists of the DeviceNet Master Unit and Slave Units. The entire network is affected when a Unit is faulty, so a faulty Unit must be repaired or replaced quickly. We recommend having spare Units available to restore Network operation as quickly as possible.

    Master/Slave A node can be either a master, which collects and distributes data, or a slave, which out- puts and inputs data according to the instructions received from the master. OMRON’s DeviceNet products are already provided with either master or slave functions in a pre- defined master/slave connection set.
