In short distance wireless data exchange between touch screen and PLC design - Industrial control -

1 a, product advantage. 485/232 data in short distance wireless transmission, no card, no operation cost

2. Because of using standard modbus RTU protocol for PLC programming does not need to write a communication program.

3。 Safe, reliable, stable 433 MHZ

4 industrial design. Support the modbus protocol of I/O acquisition control, analog input

5. Support point to point, point to multi-point application pattern

2, the product description WD1433 via wireless transmission terminal is xiamen bolian industrial users against the design of a wireless transmission terminal, it not only supports the wireless transmission of data, 485 or 232; And has a two-way digital output, digital quantity input, 2 road 2 analog input, adopts the MODBUS RTU protocol, realize the I/O data collection and control.

WD1433 433 MHZ wireless spectrum is used to communicate, good distance within 1500 meters of industrial data transmission, can use 433 MHZ wireless way to replace the traditional way of cable transmission RS485 and RS232, can direct access to all kinds of configuration software and application software, and the PLC, DCS, industrial instrumentation, sensors, touch screen devices such as connection of industrial automation control system.

using industrial-grade chip, device design, working temperature can reach - 30 ℃ ~ 85 ℃, support 5 v ~ 35 v ultra wide voltage, compact design, light in weight. The integral installation accessories, industrial terminal connection mode, ease of installation and construction. Product support configuration tool configuration, configuration flexibility. In addition, the product USES the multistage protection circuit and watchdog technology, realize the equipment in a harsh environment, the all-weather real-time, stable and reliable transmission.

three WD1433 wireless data transmission terminal, application mode is very suitable for industrial applications of short distance wireless transmission and the I/O control, is suitable for the underground operation in harsh environment and are not suitable for wiring serial port applications, through the wireless way of 485 232 to replace the cable and wireless, bringing great site deployment and construction machines and terminal, at the same time WD1433 have the function of I/O data collection and control and can easily connect all kinds of sensors, so as to achieve transmission and acquisition, control as a whole. WD1433 is widely used in power plants, steel mills, terminals, coal mine, open-air mine, oil field drilling, industrial occasions, such as digital factory, strong anti-interference ability, stable performance.

A, peer-to-peer applications mode

point-to-point transmission is one of the most commonly used mode, through the two WD1433 wireless serial port ( 232 or 485) The application of the can realize two 1 apart. 5 km range between the two sets of PLC, and between a PLC and a touch screen, a PLC, and between a PC and two other terminals of transmission and the I/O data acquisition.

WD1433 itself has the analog acquisition and digital signal acquisition and digital quantity control function, can replace some applications direct I/O data collection and control of PLC to realize the wireless is not only easy to construction and cost savings.

B, relay application mode relay transmission is mainly with one or more WD1433 as relay, so as to realize the expansion of wireless transmission distance, so as to realize 1. More than 5 km of wireless data transmission.

C, point to multipoint application mode

point to multipoint is also a kind of mode, collection of commonly used industrial application field have more than one patch need to gather data to a control or on the server. Industrial field generally adopts the Modbus communication protocol, for each node by means of polling data and control each node; Or each node active will report data collected on the master node for processing, storage and distribution.

4, 1, industrial data acquisition applications and industrial control ( Industrial instruments, meters, terminal)

2, digital factory, digital production line ( Between PLC and PLC, the data transmission between the PLC and touch screen)

3, meteorological data monitoring and publish

4, wireless LED release system may gather and power status, power, temperature and humidity monitoring

6, short distance wireless meter reading, wireless sensor data transmission

7, robot control

8, and residential buildings ( Smart home) Control

9, 485 or 232 wireless transmission of other occasions

10, wireless transparent transmission occasions I/O
