Haiwell PLC Introduction

Haiwell PLC Panel

Haiwell PLC Panel


Haiwell PLC is a versatile high-performance programmable logic controller, which is widely used in plastics, packaging, textiles, food, medical, pharmaceutical, environmental, municipal, printing, building materials, elevators, central air conditioning, numerical control machine tools and other fields of systems and control equipment. In addition to its own various peripheral interfaces (digital input, digital output, analog input, analog output, high-speed counter, high-speed pulse output channels, power supply, communication ports, etc.), it is also expandable with all types of extension modules for felixable configuration.

Haiwell company owns the 100% independent intellectual property rights over both its hardware and software products, all products can be customized according to customer’s requirements to meet the different needs of various industries.

Haiwell PLC Features

l Ethernet +

Host PLC and remote modules support Ethernet communication, host PLC support Ethernet port and 5 RS232/RS485 serial communication ports working simultaniously. Support N:N network type, support remote programming, debugging, monitoring and data exchange. Easy to work with other PLC modules, HMI and PC via Ethernet port.

l Life time free  firmware upgrading

Taking the lead in the function of realizing firmware upgrade in a small programmable controller. You can upgrade the system firmware through the firmware upgrade function for free, herefore the PLCs that you bought previously can also to have the latest features from Haiwell company.

l Rich network communication function

CPU host PLC supports built-in Ethernet port and 2 serial RS232/RS485 communication ports, it is expandable to 1 Ethernet port and 5 serial RS232/RS485 ports, each port can be programmed and connects to network, and all of them can be used as masters or slaves. It support multilevel networking and a variety of human-machine interface and configuration software. It can also connect to network with any third-party devices which have communication capabilities (such as inverters, instruments, barcode readers, etc.).

l Supports multiple communication protocols

Supports built-in Modbus TCP, Modbus RTU/ASCII protocol, free communication protocol and Haiwell Company’s Haiwellbus TCP and Haiwellbus high-speed communication protocols. No matter which kind of communication protocols, it only needs a simple communication instruction when dealing with complex communication functions. You will no longer troubled by the problems as communications port’s conflicts, sending&receiving control, communications interrupt handling issues and you can use a variety of protocols to exchange data easily by mixing them up in the program.

l High-speed pulse counting function

Supports 8-channel duplex high-speed (200KHz) pulse counting, and 7 kinds of counting modes (pulse / direction 1 octave, pulse / direction 2 octave, forward / reverse pulse 1 octave, forward / reverse pulse 2 octave, A / B phase pulse 1 octave, A / B phase pulse 2 octave, A / B phase pulse 4 octave), and three kinds of comparisons (single-stage comparison, the absolute mode comparison, the relative mode comparision), supports 48 segments comparision fixed value, with self-learning function.

l High-speed pulse frequency measurement

Supports 16-channel (200KHz) high-speed pulse frequency measurement, support the ways of time or pulses to measure the frequency 

l High-speed pulse output

Supports 8-channel duplex high-speed (200KHz) pulse output, support for acceleration and deceleration pulse output, multi-segment envelope pulse output function, a unique sync pulse output function makes it easy to achieve precise synchronization control. Stand-alone support 16-channel pulse width modulation (PWM), can drive 16 servo or stepper motors.

l Motion control function

Each model support for 8-channel (200KHz) motion control, supports arbitrary 2-channel linear interpolation, circular interpolation, support follower pulse output, absolute address, relative address, backlash compensation, original point return, definition of electrical origin.

l Edge capture and interrupts

CPU supports 8-channel up and down along the catch and interrupt functions, all digital inputs support signal filtering settings, all digital outputs remains set to support power output. Provide 52 real-time interrupts.

l Powerful analog processing function

AI register accesses the analog input directly, analog input support engineering conversion, sampling frequency settings, and zero correction. Available AQ registers control the analog output directly, analog output support engineering conversion and can be configured to maintain output.

l Strong password protection function

Three levels of password protection function (program files password, each block password, PLC hardware password) and prohibits the application to upload.

l Self-diagnostic function, power failure protection function, calendar (RTC), floating point operations, etc.
