("D-bus" is the name of KEYENCE's wiring-saving system for sensor amplifiers.) How many sensor amplifiers can be connected depends on the sensor amplifiers or units to be connected.
2-1 Installation and Connection to Sensor Amplifiers Installation and Connection to Sensor Amplifiers Mounting on a DIN rail 1 Align the claw on the bottom of the amplifier with the DIN rail. While pushing the amplifier in the direction of arrow (1), press down in the direction of arrow (2). (2) (1) 2 To remove the DL-CL1, raise the main unit in the direction of arrow (3) while pushing it the direction of arrow (1).
2-1 Installation and Connection to Sensor Amplifiers Procedures for connecting to sensor amplifiers The CC-Link compatible communication unit DL-CL1 must be connected to sensor amplifiers before it can provide its function. NOTICE 2 Connection and Configuration Point 1 Make sure that the power to the sensor amplifier is off before starting to connect the CC-Link compatible communication unit DL-CL1. Performing the procedure with the power on may damage the DL-CL1.
2-1 Installation and Connection to Sensor Amplifiers Make sure that the sensor amplifier connector (for DIN rail mounting type) is not askew on the side face of the CC-Link compatible communication unit DL-CL1, as shown below. If the connector is askew, the DLCL1 may become damaged when connected to the sensor amplifier.
2-2 Wiring This section describes how to wire the DL-CL1. Point 2 • Turn off the power before starting the cabling operation. • For more information about the CC-Link system, including cable length and cabling methods, refer to the document of the CC-Link master unit. Connection and Configuration Connecting to the CC-Link System Use the following procedures to connect the DL-CL1 to the CC-Link system. Usable cables For connection between the DL-CL1 and the CC-Link system, use CC-Link cables (Ver. 1.
2-2 Wiring 2 Trim the shield. Upbraid the shield braid carefully. Find the bare drain wire (twisted or flying) inside the shield braid. Twist together the unbranded shield braid and the drain wire securely, and then put on the insulating tube. Aluminum polyester laminated tape Strip the sheathed conductors. Strip approximately 10 mm of sheath from each signal wire, by removing the aluminum polyester laminated tape. Take care not to damage the signal wires. Twist together the exposed conductors securely.
2-2 Wiring Connecting the cable Use the following procedures to connect to the CC-Link connector supplied with the DL-CL1. 2 1 Connect the trimmed cable to the CC-Link connector. Insert the cable completely. Connection and Configuration Terminal name 2 Function DA/DB/DG Communication signal SLD Connect the shielded wire of the CC-Link cable. FG Ground this functional ground terminal. (Ground resistance: 100 ohm or less) Attach the CC-Link connector to the DL-CL1.
2-2 Wiring Connecting the termination resistor If the DL-CL1 is at the end of the CC-Link system, connect the supplied termination resistor to DA/DB of the CC-Link connector. Type of cable Termination resistor CC-Link Ver. 1.
2-3 Configuring the Data Link Use the following configuration procedures for connecting the DL-CL1 to the CC-Link system. Point 2 Connection and Configuration This manual covers only the functions and settings of a CC-Link master station which are required for communication with the DL-CL1. For the functions and settings related to the communication between the CC-Link master unit and CPU unit, refer to the manuals shipped with your master unit or CPU unit.
2-3 Configuring the Data Link Setting the transmission rate Set the transmission rate of the DL-CL1 to the same value as set in the CC-Link master station. Do this using the transmission rate setting switch on the DL-CL1. • Default value: 0 No. Transmission rate (bps) 0 1 2 3 4 5 to 9 156 k 625 k 2.5 M 5M 10 M Cannot be set.
2-3 Configuring the Data Link Point Each switch should be set before turning on the power. If any setting is changed while the DL-CL1 is operating, the new setting will not be applied until the power is turned on again. (The communication error indicator flashes intermittently.

3-1 CC-Link Communication and Operating Modes Selecting an Operating Mode of the DL-CL1 Select an operating mode of the DL-CL1 to suit the functions of the sensor amplifiers to be used. The specific CC-Link device configuration and the data that can be communicated using cyclic transfer vary with each operating mode of the DL-CL1. An appropriate operating mode should be determined by considering the number of link points the data that can be communicated.

3-3 Communication Methods This section describes how the CC-Link master station communicates with the DLCL1.
3-3 Communication Methods Reading Current Values (Instantaneous Flow Rate) from Sensor Amplifiers Current values can be read in the monitor modes and full modes. They cannot be read in small-memory modes. Instantaneous flow rate is read as the current value regardless of the detection mode setting. 3 Monitor mode 1 When reading current values in monitor mode 1, specify the ID numbers (in terms of current value page numbers) of the sensor amplifiers to be read to current value boxes 1 to 3.
3-3 Communication Methods (5) The current values of the sensor amplifiers of the specified ID numbers are entered into current value boxes 1 to 3. If the current value is over range, under range, or invalid, the previous value is retained without updating the current value. Use the value with the judgment value property. (6) When the "request to change current value page" command is set to 0, the "current value page change complete" parameter flips to 0.
3-3 Communication Methods Issuing a Motion Command to a Sensor Amplifier Available motion commands: See "Motion command parameters" (page 3-26). Commands can be used to reset preset values, clear errors, or for other purposes.
3-3 Communication Methods Rewriting a Setting Value of a Sensor Amplifier Available setting values: Instantaneous flow rate setting 1 (P1), instantaneous flow rate setting 2 (P2), temperature upper limit setting, temperature lower limit setting, and integrated flow quantity setting 1 Reference When rewriting any settings other than listed above, use the procedure described in (page 3-21).
