end. Under the mode of virtual serial port, the serial port software connected to virtual
serial port can be used without any configuration.
When used as Modbus gateway, 5143D supports Modbus TCP to Modbus RTU, so as
to realize data acquisition of RS485 Modbus RTU device by upper computer using
Modbus TCP protocol. On the contrary, it can be used if RS485 terminal as the master
station. 5143D supports more advanced Modbus gateway functions, including
configurable Modus gateway ZLMB, storage Modbus gateway, etc., which fully meets
all kinds of configuration and usage of Modbus gateway. The multi-host feature allows
multiple computer master stations to simultaneously access one RS485 slave device.
When used as MQTT gateway, the device can upload the serial port data to MQTT
server in the way of transparent transmission through MQTT protocol. Supported
servers include BAIDU cloud MQTT, ALI cloud MQTT, China mobile OneNet platform,
etc. It is supported to parse the collected Modbus RTU or non-standard serial port
data into JSON format and encapsulate it into MQTT packet for uploading.
It supports JSON format to upload and collect data, and the data is automatically
collected. The collected data supports Modbus RTU, 97 version of 645 meter, 07
version of 645 meter, and various non-standard RS485 protocols. The user can
configure the uploaded data format and JSON keywords with ZLVircom. When
uploading, MQTT protocol, HTTP POST protocol, HTTP GET protocol, transparent
transport protocol and various non-standard network protocols can be supported.
Among them, ZLAN5143DN model supports P2P networking, no need to relay
through the server, and connect the device through ID.
ZLAN5143D has powerful functions of IOT gateway, which is very suitable for
collecting all kinds of RS485 instruments and sensors in the industrial field, including
collection of local network or uploading to cloud server for independent collection and
posting.
ZLAN5143D can be applied to:
As the gateway of IoT and the communication bridge between devices and cloud;
