Industrial serial port server
The industrial-grade serial port server developed by Zongheng Intelligent Control Technology provides various interfaces such as DI, DO, AI, and RS485. Supports local logic operations, DO remote follow AI/DI, configure cloud real-time monitoring PLC, automatically obtain IP address, DNS domain name resolution and other special functions. It has a variety of networking methods and supports one-to-one and one-to-many networking. This product can be widely used in industrial automation production monitoring, water plant automation monitoring, etc.
How to make serial port devices in the automation field have networking capabilities and connect to the Internet immediately? The serial port networking server allows traditional RS-232/422/485 devices to be immediately connected to the Internet. The device hardware that uses TCP/IP-based serial port data stream transmission to control and manage is a bridge specifically designed for serial port to Ethernet connections. The serial device networking server is like a microcomputer with a CPU, real-time operating system and TCP/IP protocol, which facilitates data transmission between serial ports and network devices.
DO follows Al from a distance
ZHHC1661 can be used in combination with ZHC1931 and other devices to achieve distance following A output logic action.
Logic follows – local logic
Local logic operations do not need to rely on the cloud. Users can customize the conditions that trigger A0 changes. By simply modifying the relevant parameters of condition control, the corresponding linkage function can be quickly realized.
Logic follows – inter-device logic

Support platform monitoring
Multiple platforms such as configuration and cloud platforms simultaneously monitor PLC data
Industrial serial port server application
In the automatic drainage monitoring of water plants, put a digital liquid level sensor into the pool and connect it to the ZHC1661 of Zongheng Intelligent Control. When the water level reaches the threshold height, the ZHC1661 will trigger an alarm and remotely control the ZHC1931. When ZHC1931 receives the alarm information, it will handle it accordingly, control the solenoid valve, and turn on the water.
