If Customers have their own servers, and the ZHC4661 can communicate directly with the client server after simply configured. The ZHC4661 follows the Modbus RTU/TCP protocol and also supports 485-channel transparent transmission protocols.
Configuration software docking
ZHC4661 has an RS485 interface, which supports the standard modbus RTU/TCP protocol. The configuration software can directly read and command the ZHC4661 through the RS485 interface.
If customer does not have a cloud server
When some customers use the configuration software, they can't directly connect the PC and S485. The ZHC4661 supports the ZH-Cloud transmission. The customer only need to install the virtual serial port, the data of the ZHC4661 can be forwarded to the local serial port of the PC, which is more convenient and quick.
(Also applicable to scenarios without a cloud server)
The ZHC4661 supports networking functions and supports one-to-one and multiple-to-one networks. This need is very practical for some specialization scenarios.
RS485 automatic acquisition
Support automatic acquisition, active reporting, can dynamically modify collection instructions, collection cycle. Reduce server processing
Analog auto-calibration threshold reporting
The ZHC4661 presets the analog linear calibration parameter value, the user only needs to modify the k/b value to achieve the linear calibration effect. In addition, the effect of analyzing the analog data can be realized by adjusting the k/b value, and the threshold will be reported.
Support automatic identification of Modbus RTU/TCP protocol
Adaptive Modbus RTU/TCP protocol, the data format replied by the ZHC4661 is consistent with the data format sent by the cloud.
TCP CLient communication
The serial server initiates a TCP connection to the server actively. If the connection fails, the connection is repeated repeatedly until it succeeds. If the connection is completed, the server and serial device can carry out two-way transparent data transmission.
