2 Introduction

This document demonstrates the communication between an AC500 and the SQL database over TCP. This Application example works only with one PLC.

2.1 Hardware and Software requirement

NOTICE

The following configuration is used in this document. The newer version of hardware and software should work, however it should be tested by the user himself.

Hardware Software AC500 CPU:PM564 ETH, FW: V2.1.3 PS501 Control Builder Plus: V2.1.0

Industrial Ethernet Switch NS-205 XAMPP V1.7.4 or higher

Server Microsoft Windows e.g. XP, Vista, Win7

Ethernet cable

2.2 Connections

www.infoPLC.net


3 Server Applications

This chapter will show all programs and settings they are required.

3.1 IP settings

The Server has to be in the same network as the CPU. Change the addresses of the Server to: IP address: 192.168.8.253

Subnet mask 255.255.240.0

Gateway: 0.0.0.0 or address from the router

3.2 XAMPP (contains: Apache, MySQL, PHP and Perl)

This chapter will you show, where can you get the software and how to configure this.

3.2.1 Configure XAMPP

Go to http://www.apachefriends.org/en/xampp.html and download XAMPP in the newest version. After this, install the software and restart your PC.

Start the web browser and insert “localhost” into the address bar. The following window will displayed.

www.infoPLC.net


Now, we have to secure the application. Push the button “security check” on the left menu. The following window will displayed. Click on the link in the red marked border and follow the instructions.

DANGER!

It’s very important that the MySQL and the XAMPP directory receive a password.

In the next step, you have to reboot the Server to take effect.

www.infoPLC.net


3.2.2 Configure MySQL database

After we have secure the directories, we have to login into the database. Insert “localhost/phpmyadmin” in the address bar in your browser. The following screen will show.

Now, insert the password that you set the chapter before. For the first login, the username is “root”. You can change this, if you logged in.

If the login was successful, you see the following screen.

www.infoPLC.net


If you want, you can change the username and the password. Push on “Rights” as shown in the following screen. Now, you can create a new user and a password. This step is not essential.

www.infoPLC.net


3.2.3 Create a database and tables

Now, we want to create a new database and import a table into this. At first, click on database as shown in the red border.

The green border marked the field, where you can insert a name for the new database. Insert the name “sql_ac500” and push “Create”. The following screen will displayed.

www.infoPLC.net


In the next step, we want to import a file. This contains a table and measurements.

Push on “import” as shown in the red border.

Now, you have to choose the file. Click on “Browse” and navigate to the folder “AC5002SQL/import file/ test_1.sql” in the zip file. To import the file, press “OK”.

If the file has successfully imported, you will see the following screen.

www.infoPLC.net


CAUTION

!

Repeat the last step and import the file: “status_message.sql”. It’s important that this file is imported. If you forget it, you will get a warning in the PHP script.

Now, you can take a look at the data sets. Push on “test_1” at the left side.

www.infoPLC.net


3.3 PHP-Script

This chapter shows you where the files must be copied. The next step is to configure the important variables.

3.3.1 Copy files

Copy the required folder “sql_ac500” with all files to the following folder: C:\xampp\php

3.3.2 Configure the PHP-script

After you have copied your files, open "settings.php" with a text editor. Here you can change miscellaneous settings. Important settings: $db_host = "localhost"; // IP where the database is working e.g. “localhost” $db_user = "root"; // username of the database $db_pass = "***"; // password of the database $db_data = "sql_ac500"; // name of the database define(“lang”, 1) ; // language selection: English=2; German=1; $db_value_table = "test_1"; // name of the table where the measurements where

insert (default) $db_report_table ="status_message"; // name of the table where the messages / warnings

and errors where saved $ip_sps = "192.168.8.252"; // IP of connected PLC $address = "192.168.8.253"; // IP of the PC where the script is running $PortNr = "2158"; // port of the PC which will opened

www.infoPLC.net


Now, we have changed the important settings. If you want, you can show more messages/warnings and errors in the command prompt. Be careful it’s getting confusing very fast. At these settings you don’t see any messages, warnings and errors. define ("show_messg", FALSE); // disable messages define ("show_warng", FALSE); // disable warnings define ("show_error", FALSE); // disable errors At these settings you will se all messages, warnings and errors. define ("show_messg", TRUE); // enable messages define ("show_warng", TRUE); // enable warnings define ("show_error", TRUE); // enable errors

3.3.3 Execute the script

Now, we want to start the command prompt. If you using Microsoft Windows 7, then push: Start -> Programs -> Accessories -> Command Prompt

www.infoPLC.net


A new window will pop up. Navigate to the right folder, where your have copied the files. Normally, the files lay in this directory: C:\xampp\php\sql_ac500\ We have copied these a few steps before.

After you have insert the path, confirm with Enter. Now we want to start the script. Please insert the following line to run the script: “..\php AC500_zu_PHP.php” Push Enter to start the script. If you successfully, the following lines will displayed in the Command Prompt. ********************************************************************************************* Ersteller: Torsten Ruland Firma: ABB STOTZ-KONTAKT GmbH Projekt: Kommunikation der AC500 Steuerung mit MySQL Datenbank-Server ueber TCP ********************************************************************************************* "Verbindung Erfolgreich" "[08][801] Socket 192.168.8.253:2158 wurde geoeffnet"
