1. System Overview
In the traditional concept, it is rather cumbersome and complex to remotely connect HMI via Ethernet. Users not only to consider the security issue, but also to set up complex network parameters. In addition, subject to the stage of the network environment, users have to do everything possible to think of ways through all levels of routers and switches. And an independent IP can only correspond to one HMI in tradition sense of the remote control. The WECON PI8000 series HMI will solve all of those problems. The solution of WECON HMI remote access is “Everything is possible with one network, one HMI, one cable,” No matter where in the HMI, users can easily remote access HMI through the network, to achieve exclude exceptions and resolve them in the first time. In local area network or in remote Internet, users could make HMI connect to Ethernet by one cable without setting any parameters. All complex network settings could be set by WECON remote access system.

2. System Features
1) No need to set any proxy servers, routers, or switches, simply connect one cable for Ethernet
2) Grading management of multiple HMI, easy maintenance and operation;
3) A variety of access mode, easy to use;
4) Multiple users could access one HMI at the same time;
5) A secure connection

3. System components
1) Part 1: WECON PI8000 Series HMI;
2) Part 2: WECON Smart APP for Android and IOS (IOS is in Chinese now);

 1.Introduction

Automatic edge banding machine can automatically complete the work sheet edge. Mainly divided into two categories: linear edge and edge curve.

2.Technical specifications

Feeding→Transportation→Block→Rough trimming→Refinement→Side slot→Lower slot→Blowing→polishing→complete。

3.Main features

With the rise and development of panel furniture, the production technology of panel furniture becomes more and more mature, the edge technology is from the hand edge to mechanization production and continuous production. Mechanical sealing adopts various continuous sealing machine, using the banding strip to seal up the plate side edge rapidly. It is not only accelerates the edge glued and improves the production efficiency, but also to ensure the quality of the edge. Good physical properties of the edge banding machine, have thin and uniform layer, do not need to be stored and Immediately follow the process after the edge banding.

4.Solution

The control system uses the Wecon HMI LEVI700LK, the host of PLC uses LX3V-48MR.

The general automatic linear edge banding machine by paste compaction device, edge banding before and after butting device, upper and lower edge trimming device, tracking the trimming device, scraping the edge device and a polishing device and other components, some also equipped with milling cutter, sand on the edge of the sanding head and a heating device. Start from the feed side when debugging, operating in accordance with the order step by step , until the end of the material, so that it is both fast and accurate.

2. Function code list

1. Instruction description

2. Operation
Step Control (STL) is controlled by several operating procedures (S0,S1……Sn).
Step Control method’s feature is that after taken into considerations for each control step and divided the complex procedure into successive steps, it greatly reduces the interdependence between each step and the complexity involved in programming.
Every movement executed in each status are programmed by other instructions in the ladder diagram. STL is the initiation instruction for step procedures, and RET is the ending instruction for a step procedure.
After the instruction is executed, it returns to the bus bar.
SET S[k]([k] is in decimal) is the only instruction for initiating STL transitions. Note: STL—RET instructions cannot be used in sub-programs.
When transition is happening from current status (S0) to next status (S1), the actions under the two scanning cycle conditions will both be executed; when the next scanning cycle is being executed, current status (S0) will be reset by the next status (S1), and the actions under the current status (S0) will not be executed. All OUT components’ inputs will be interrupted.
Generally speaking, RET will be omitted between each step procedures. Therefore, it will seem a RET is shared by several STL. When STL is programmed and RET procedure is not, error message will appear.

General
Many customers need to change the HMI clock, this document provide three methods for it.

Solution 1
Click the [Sync Clock (T)] in downloading window, when connecting HMI to PC;

Solution 2
Using system-special addresses to change the HMI clock;

Solution 3
Changing the clock in Setup screen;
Note: If HMI version was old version before May 2016.Please don’t use the Setup HMI to change Date/Time.Because the older version HMI have probability to make HMI into black screen.And it is hard to repair.It must to update HMI system by USB flash disk.The problem probability is 1%. So,if HMI is old version before May 2016,please use special address to modify the time by solution 1 or solution 2

How to check HMI version time?
For example:187003160119021(the time is January 2016)

1. General
With the PI series HMI is widely used in various fields, vertical screen display is required by more and more users.

2. Solution for switching screen
When create a new HMI project, users can select the [HMI model] and [Angle] in New project window as Figure 2-1 shows, the project will change according to the settings.

When programming is competed, please download the program into PI HMI, the screen will be
switched automatically.
