1. Establishing the PLC-Link (Ethernet PLC-Link) [Keyence KV Series] ✎Checking the Global Settings of the CV-X Series This section describes how to establish the PLC‐Link. [Important] If it fails, establish a one-to-one connection between the PLC and CV-X, and follow this manual to configure the settings and check the operations. Confirm that it operates properly, and change settings if necessary.
✎Configuring the KV Series Settings 1 Start KV STUDIO with the PLC connected to the computer, and select [File] > [New project]. 2 Enter the "Project name", select the "PLC model", and then press "OK". 3 Select [Read unit setting] in the "Confirm unit setting information" dialog box. 4 In the workspace, click the link unit or CPU unit that will be connected to the CV-X via Ethernet to start "Unit Editor", and set up the IP address and Port No. of the KV Series on the "Setup unit(2)" tab.
Select [Convert] > [Auto-assign relay/DM] in the Unit Editor to assign a device. Alternatively, you can use this icon. 6 Save the changes and exit the Unit Editor. 7 Select [Monitor/Simulator] > [Transfer to PLC] in KV STUDIO. Alternatively, you can use this icon. 8 Restart both the CV-X Series and the KV Series. * Start the KV Series first, and then start the CV-X Series. If "Initializing PLC- Link...
2. Establishing the PLC-Link (RS-232C PLC-Link) [Keyence KV Series] ✎Checking the Global Settings of the CV-X Series This section describes how to establish the PLC-Link. [Important] If it fails, follow this manual to configure the settings and check the operations. Confirm that it operates properly, and change settings if necessary. 1 On the "Global" menu, select [Communications & I/O] > [PLC-Link]. Configure the PLC-Link settings.
✎Configuring the KV Series Settings 1 Start KV STUDIO with the PLC connected to the computer, and select [File] > [New project]. 2 Enter the "Project name", select the "PLC model", and then press "OK". 3 Select [Read unit setting] in the "Confirm unit setting information" dialog box.

3. Outputting the Measured Value/Judged Value (PLC-Link) [Keyence KV Series] ✎Configuring the Output Settings Set the measured values/judged values to output in "Output Settings". This section describes how to assign tool measurement values/judgment values. (In the description, the following are output: 1: Total Status Value, 2: T100: Pattern Search. Pattern X Position Result, 3: T100: Pattern Search. Pattern XY Position Result, 4: T101: Area. Area Result, 5: T102: OCR.
✎Checking the Output Format/Flow for the Data Memory 1 Check the data memory and word count to use for the result output. Use "Result Output Address", "Result Ready Address" and "Result Ack Address" in [Global] > [Communications & I/O] > [PLC- Result Output Address: Specify the first data memory for the result data output by CV-X. * The result data is stored starting from this address by 2 words per data item (2 words per character).
3 Representative data output procedure Operations of data output procedure depending on "Result Output Settings" configured in step 1 1. When both "Acknowledge result output completion" and "Enable Handshake" are checked Follows the above procedure, and guarantees that all result data output from CV-X is sent to the PLC. However, if the PLC repeats measurement without controlling Result Ack Address (bit), the output buffer of CV-X overflows, and trigger input becomes impossible. 2.
4. Controlling the Controller (PLC-Link) [Keyence KV Series] ✎Checking the Global Settings of the CV-X Series 1 On the "Global" menu, select [Communications & I/O] > [PLC-Link] to open the global "PLC-Link" settings screen. * The screen on the left shows that Mode is set to "PLC- Link (Ethernet)", but the settings (in the red frame) in this section (Controlling the Controller) are the same as those of "PLC- Link (RS232C)". 2 Check the setting items necessary for controller control.
✎Command Processing Flow To control the controller via PLC-Link, use the number-specified commands. 1 Refer to "Control/Data Output via Commands" in the user's manual to check the commands to use and the formats of the number-specified commands. Here is an example of using the PW command (command No. 24) that switches the program setting. The following must be specified to execute the PW command: Command No. (24) SD card No. (d) of the switch target program setting Setting No.
✎Command Processing Flow 2 Command execution procedure There are two methods to execute a command: "PLC Terminal" and "Polling". If "Polling" is selected, terminal control is not required but the communication for polling is required, and the command execution may be slower than "PLC Terminal". "PLC Terminal" Executes a command when the input terminal IN15 "PLC Terminal" is set.
✎ Command Execution Procedure Example: Save Settings (SS Command) Here is an example of a representative command execution procedure. This section explains an example of executing the SS (Save Settings) command, which does not use a command parameter, with Command Execute Event set to "Polling". The screens with blue frames show when the "Registration monitor" function of KV STUDIO is used for confirmation. 1 Check the SS (Save Settings) command operation. 1. Enter "12", the SS command No.
✎Command Execution Procedure Example: Switch Program Setting No. (PW) Here is an example of a representative command execution procedure. This section explains an example of executing the PW (Switch Program Setting No.) command, which uses a command parameter, with Command Execute Event set to "Polling". The screens with blue frames show when the "Registration monitor" function of KV STUDIO is used for confirmation. 1 Check the PW (Switch Program Setting No.) command operation. 1.
✎ Command Execution Procedure Example: Rewrite Judgment Conditions (DW) Here is an example of a representative command execution procedure. This section explains an example of executing the DW (Rewrite Judgment Conditions) command, which specifies numeric values as command parameters, with Command Execute Event set to "Polling". The screens with blue frames show when the "Registration monitor" function of KV STUDIO is used for confirmation. 1 Check the DW (Rewrite Judgment Conditions) command operation.
✎Command Execution Procedure Example: Rewrite Registered String (CW) Here is an example of a representative command execution procedure. This section explains an example of executing the CW (Rewrite Registered String) command, which specifies a string for the command parameter, with Command Execute Event set to "Polling". The screens with blue frames show when the "Registration monitor" function of KV STUDIO is used for confirmation. 1 Check the CW (Rewrite Registered String) command operation. 1.
