During use, users can also easily program and calibrate themselves. 2, Communication Protocol Communication interface: 1 standard RS-485 communication interface. Communication Protocol: Supports two protocols, the character protocol defined by the command set and the MODBUS RTUcommunication protocol. The module automatically recognizes communication protocols and can achieve network communication with various brands of PLCs, RTUs, or computer monitoring systems. Data format: 10 digits. 1 start bit, 8 data bits, and 1 stop bit. The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set; The communication network can reach a maximum distance of 1200 meters and is connected through twisted pair shielded cables. High anti-interference design of communication interface, ¡À 15KV ESD protection, communication response time less than 100mS. 3, anti-interference Checksums can be set as needed. There is a transient suppression diode inside the module, which can effectively suppress various surge pulses, protect the module, and the internal digital filter can also effectively suppress power frequency interference from the power grid.FAQQ: How to contact you?A: Please contact us via email or online customer service
