## Article

#### Introduction

The TCP - KP - I404 network relay is an IoT remote control device introduced by Clay man Technology. It can realize remote control and data acquisition of TCP network. The equipment adopts industrial-grade design scheme, equipped with 32-bit ARM processor and 10/100M Ethernet network chip. It has the characteristics of fast speed, strong computing power, high stability and strong anti-interference ability. Users can rest assured to use in industrial environment. The device supports 4 relay outputs and 4 isolated inputs. The relay supports real-time control, delay control and input-output linkage control, daily timing control and custom date control, etc. It is suitable for use in more different occasions and meets the requirements of more users. Input interface status supports passive upload and active timing upload.

#### Example of control instructions.

The secondary development is simple and convenient. The parameter setting, relay control, and input interface status are all controlled by the AT command. The AT command is in the ACSII format, ending with a carriage return line feed, for example:

For a more detailed description of the AT command, please see "TCP-KP-C Series Network Relay AT Command Manual.

#### Functions

1. Relay real-time control, command response speed is fast.

2. Relay delay control, accurate delay, maximum support 99999 seconds delay.

3. Each relay supports 10 daily cycle control time points.

4. Each relay supports 10 custom date control time points.

5. The relay status supports power-down save and power-on recovery.

6. Input and output linkage supports real-time linkage, jog linkage and contact linkage.

7. Input interface status supports passive instruction reading and active timing upload.

8. The network supports four modes: TCP_Server, TCP_Client, UDP, and UDP_Server.

9. Static IP can be set or automatically obtained through DHCP.

10. Support 5 connections in TCP_Server mode.

11. Support DNS domain name resolution, access to remote servers.

12. Support network registration package for server registration and authentication.

13. Support network heartbeat packets, the network automatically reconnects when there is no response timeout.

14. The device firmware can be upgraded via the network and customized without returning to the factory.

15. With the factory reset button, the device parameters are restored to the factory state with one button.

16. The parameter is saved after power-off. It does not need to be reset after power-on.

#### Secondary development

Customers can develop their own management software according to the needs of the project, and Cuiren Technology provides relevant secondary development materials.
1. Provide a complete control instruction manual. The customer only needs to write a TCP software. After the software establishes a SOCKET connection with the device, it can send a command control relay:

2. Provide a test software source code written in C++ for user reference, shortening the user's secondary development cycle.

3. The relay can access the remote server through a fixed IP or domain name. The user can develop software to manage the relay on the remote server to realize platform control.

#### Personalized function customization

The user can customize the firmware of the relay, such as: modify the command format, modify the relay function. Custom firmware does not need to send the device back to the factory, just upgrade the firmware online via the network.
