CNC Gateway User Guide: KND CNC Integration with CNC gateway

In this tutorial, we will focus on integrating KND CNC Integration with the EG8200Mini CNC gateway. This lesson provides a step-by-step guide to help you set up and configure the connection.

Previously, we have covered:

How the EG8200 Mini CNC Gateway interfaces with Siemens CNC systems

How to Integrate the CNC Gateway with Mitsubishi CNC

How to Integrate the CNC Gateway with New Generation CNC

How to Integrate the CNC Gateway with HAAS CNC

How the EG series CNC gateway interfaces with Maritx CNC

How to Integrate the CNC Gateway with FANUC CNC

This lesson will provide a detailed explanation of KND CNC systems.

CNC Compatibility: Knd K1000 / K2000, system version V4.3 or above

1. Hardwareverbinding

The Knd CNC protocol uses Ethernet communication. Therefore, it is only necessary to ensure that the LAN port IP of the gateway and the CNC device are within the same subnet. (Note: In special cases, they can be on different subnets, but routing must be configured—please consult technical support for details.)

In this example, the IP addresses are assigned as follows:

Address: 192.168.2.201
Connection Timeout: 5000 ms
Heartbeat Interval: 60000 ms
Data Timeout: 2000 ms
Data Interval: 1000 ms (read cycle)
Loop Wait: 1000 ms (interval between reading data points)

3.2 Data Point Settings

Check/select the required data points.

3.3 Testing

Click Deploy. Data will be printed every few seconds—verify that the read data points match the actual values. If they do, the communication is successful!

4. Additional Notes

Please refer to the Data Point Reference Table for details.

5. KND Network Configuration

5.1 Device Information Verification

1. Confirm Model
   The system shown is K1TCi. Any system with the suffix “i” generally supports Ethernet communication.

2. Locate the Ethernet Port
   The Ethernet port is commonly found at XS92 (silkscreen label), as shown below. Other common locations include the side of the CNC control panel or the back of the machine tool electrical cabinet.

3. Verify CNC System Software Version
   Supported software versions:

• V4.3b standard software

• V5.0c and above standard software

• K1000TTCi standard software released after 2017

• Some specialized machine software

Click the Diagnostic button on the panel, then click the System Maintenance button to view the system version information.

In the example, the NC version is 5.0c, which supports data acquisition.

5.2 System and Network Configuration

1. Set System Parameters
   a. Enter the Settings page, press the Parameter Switch, then press → to open the system parameter switch. Any alarm messages can be ignored.
   b. Enter the Parameter page and switch to Input mode.
   c. Enter P6.2 consecutively, then press Enter to locate the NETAPI parameter.
   d. Press 1 and then Enter to set this parameter to 1.
   e. Return to the Settings page and turn off the parameter switch.

2. Set Network IP
   a. Press the Program button twice consecutively to enter the File Management page.
   b. Press → twice (or press the “Switch Device” soft key twice) to enter the Netwerk settings.
   c. Locate the Parameters soft key. (Note: Some systems require pressing the rightmost soft key multiple times to access the next page.)
   d. Configure the network parameters: IP address, subnet mask, and gateway.
   Opmerking: De Server setting is unrelated to KAPI and can be ignored.

Opmerking: On some systems, network parameters start from parameter 8100 in the Parameter page.

5.3 Communication Testing

1. Ping the IP
   Example: ping 192.168.1.5

2. Telnet Command
   Example: telnet 192.168.1.5 8000

The figure below shows an example when the port is not accessible. If the port is open, a black console window will appear.

FAQ

Q1: The network is unreachable. What should I do?
A: Try restarting the device, checking the Ethernet cables, and verifying that the Ethernet port LEDs are blinking.

Q2: The CNC system version is too low. What should I do?
A: Consider upgrading the CNC system to a supported version.
