The safety precautions that are provided are extremely important to safety. Always read and heed the information provided in all safety precautions. The following notation is used.
  • Page 8 ■ Precautions WARNING Do not touch the terminals while power is being supplied. Doing so may possibly result in electric shock. Make sure that the terminal cover is installed before using the product. Always provide protective circuits in the network. Without protective circuits, malfunctions may possibly result in accidents that cause serious injury or significant property damage.
  • Page 9 CAUTION Make sure that the product will not be adversely affected if the DeviceNet cycle time is lengthened as a result of changing the program with online editing. Extending the cycle time may cause unexpected operation, occasionally resulting in minor or moderate injury, or damage to the equipment.

  • Page 22: Compoway/F Communications

    SECTION 1 CompoWay/F Communications This section describes communications using CompoWay/F. Communications Method ..........1-1-1 CompoWay/F Communications Protocol .

  • Page 23: Communications Method

    CompoWay/F is OMRON's unified protocol for general purpose serial commu- nications. Featuring a unified frame format and commands that are compliant with FINS, which has a record of successful use with OMRON programmable controllers, CompoWay/F makes communications easy between multiple components and a computer.
  • Page 24 Communications Method Section 1-1 The exchange between the command frame and response frame is explained below. 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.

  • Page 26: Frames (Compoway/F Communications)

    Frames (CompoWay/F Communications) Section 1-2 Frames (CompoWay/F Communications) Based on CompoWay/F protocol, commands from the host computer and responses from the K3HB take the form of frames. The data comprising command frames and response frames are explained below. In the following explanation, an “H” following a numeric value (for example 02H) indicates that the value is a hexadecimal number.

  • Page 27: Fins-Mini Text

    FINS-mini Text Section 1-3 End code Returns the result of the command executed as instructed by the command frame. FINS-mini Text of the response Response text Code that indicates the end of the text (03H) Block Check Character Stores the result of the BCC calculation from Node No. to EXT.

  • Page 29: Variable Areas

    Variable Areas Section 1-4 Variable Areas The area used for data exchange when communicating with the K3HB is called the “variable area.” The PV is read and various setting data are read and written using the variable area of the K3HB. Operation commands and reading of machine attributes do not use the vari- able area.

  • Page 30: Reading The Variable Area

    Reading the Variable Area Section 1-5 For example, if the PV of the K3HB is 105.0, it will be read as H'0000041A (105.0 → 1050 → H'0000041A). Reading the Variable Area The data area is read by setting the required data in the following FINS-mini command text format.

DeviceNet communications enable controlling operation, collecting measurement data, and writing settings from a host computer or PLC.
  • Page 72 Features Section 1-1 1-1-3 Using DeviceNet Remote I/O The master and K3HB-DRT Digital Indicators can share I/O by using remote I/ Communications O communications. Data in the K3HB-DRT Digital Indicators, such as mea- surement values and comparative set values, can be allocated for communi- cations with the master to enable sending and receiving the allocated data via remote I/O communications without requiring special programming.
  • Page 73 Features Section 1-1 1-1-6 Remote I/O Communications Read/write table data is automatically read and written when communications start. The Communications Write setting must be set to ON to write data from the master to the K3HB-DRT. Data will not be written to the Digital Indicator if the Communications Write setting is OFF.

    SECTION 4 Remote I/O Communications This section describes the input (IN) areas and output (OUT) areas that K3HB-DRT Digital Indicators can use for remote I/O communications. The methods to allocate data for master communications are also described using sample programming. Overview .

  • Page 87: Overview

    Overview Section 4-1 Overview I/O memory in the master can be allocated to data from the K3HB-DRT Digital Indicator, such as data from the Digital Indicator’s variable area, merely by specifying what Digital Indicator data is to be transferred to where. Data is automatically exchanged between the master and Digital Indicator, allowing the Digital Indicator to be controlled and monitored from the master without requiring special communications programming.
