ENET-MB function

1. Install on a 35mm rail, directly connect to the RS485/RS232 interface of Modbus RTU/ASCII equipment through the communication cable, and connect to the external 24VDC power supply.

2. Integrate WEB server, set device parameters and run diagnosis through web page, and set login protection password to prevent tampering with configuration data.

3. This product is suitable for Modbus RTU/ASCII network upgrade, and can cooperate with the host unit software that supports Modbus TCP to directly read the data of the device through this module.

4. Support asynchronous and uninterrupted Modbus TCP access mode, which is different from the traditional master-slave answering half-duplex mode, providing more efficient data access. That is, the client's Modbus TCP request can send multiple Modbus TCP requests at the same time without waiting for the device's reply, and the module will automatically reply to the response frame asynchronously.

5. The serial port supports RS485 and RS232 optional, and the baud rate supports 9600bps~115200bps optional.

6. 2KV surge protection, ESD electrostatic protection, high-strength anti-electromagnetic interference.

7. When connected to Modbus RTU/ASCII slave, multiple PCs are allowed to collect PLC data at the same time, and the real-time and reliability of data communication are fully guaranteed.

8. Support the user side to realize firmware update through Ethernet, provide firmware that integrates more functions for free, purchase hardware once, and upgrade it permanently.
