Products Description
Product Definition and Core Value
The Nexisense ZLAN5143BI Server/Modbus Gateway is an industrial-grade communication core device that integrates a serial server and Modbus gateway function. Designed for harsh environments, it offers surge protection, electrostatic discharge (ESD) immunity, and electromagnetic interference (EMI) shielding. It is widely used in remote data acquisition,industrial automation, and geological disaster monitoring.
Unlike ordinaryserial servers, the Nexisense ZLAN5143BI Server/Modbus Gateway uses a dual isolation design: 2500V isolation for RS485/RS422 communication ports and 3000Visolation for the power supply, ensuring safe and stable communication operation.
Nexisense ZLAN5143BI Server/Modbus Gatewayl WorkingPrinciple
The Nexisense ZLAN5143BI Server/Modbus Gateway supports twoworking modes:
Transparent Mode: The serial devices are seamlessly mapped to the network side via the Nexisense ZLAN5143BI Server/Modbus Gateway, supporting TCP Server/TCP Client/UDP communication protocols, enabling the network expansionof traditional serial devices.
Modbus Gateway Mode (Storage Mode): The device actively collects and stores data from ModbusRTU devices, which can then beread by the network side via high-speed data retrieval, reducing the polling delay ofthe master station and improving communication efficiency.
The deviceincorporates protocol parsing and caching mechanisms internally to facilitate protocol bridging and intelligent data scheduling, making itcompatible with various upper-level machine platforms.
Core Structure and Interface Analysis
The Nexisense ZLAN5143BI Server/Modbus Gateway adopts an industrial-grade metal shielding case (SECC) combined with power and communicationinterface isolation, surge protection, and electrostatic discharge protection, ensuring stable operation in lightningand high electromagnetic environments.
Interface Support:
RS232, RS485, and RS422serial interfaces (RS422 requiresoptional configuration)
Power input supports DC Q2.1 standard plug and terminal block, input voltage range:18V~36V (12V version available on request)
DIN rail mount accessories included, suitable for cabinet/control box deployment
Indicator Lights: Power, networkstatus, TCP connection status, serial communication indicators, facilitating maintenance and faulttroubleshooting.
Measurement and Data Processing Methods
In Modbus Gateway mode, the Nexisense ZLAN5143BI Server/Modbus Gateway allows users to configure polling intervals, slave addresses, function codes, register addresses,etc., to periodically collect data from slave devices and store it in internal memory.
The masterstation can then read the cached data over TCP, avoiding redundant requests,which significantly improves the Modbus TCP read/write efficiency and is ideal for scenarios with largenumbers of concurrent slave devices.
