Siemens LOGO PLC Ladder Programming Steps

Following are Step by Step instruction to Program Siemens Logo PLC

Siemens Logo PLC

Click on “Siemens LOGO”

Click on “siemens rse”

Click on “StartLOGOComfort”

Wait…
You will find the work pad where you have to write FBD programme
Use “menus” given at the top and bottom to develop a FBD programme.
Find Tools toolbar, Standard toolbar, Menu bar and Status bar.
Entering a New program :

Click on “File”
“New ”
Create a program using Toolbars and Function blocks (Constants, General and Special functions)
• You can then place any of those functions on the drawing board simply by clicking on the drawing board in the desired position. The function on the extreme left is selected by default but you can select any of the others by clicking them with the mouse.
• It is not necessary to position the objects precisely at this point.
• To complete the circuit, the individual blocks have to be linked with one another. To do so, you choose the button on the tools toolbar.
• Give the label and block comments to complete the documentation of the program.

When PLC program is ready…

Then “Simulate” the program using menu at the bottom.
“Save” the programme if it is ok or edit it.
Set the path for down loading your program to the PLC.
Click on “Tools ”
“ Options “
“ Interface”
Select “COM1” port for communication from PC to PLC and vice versa.
Click on “OK”
Then “Download” the programme to PLC using red downward arrow at the top menu.
Wait…..
If takes some time to make a file that is suitable for downloading
Verify the logic with help on I/O simulation module.
Try for more programmes…

Power Amplifier with voltage regulator 4 × 50 Watt TDA8588

Power Amplifier with voltage regulator 4 × 50 Watt TDA8588 The TDA8588 is a multiple voltage regulator combined with four independent audio power amplifiers configured in bridge tied load with diagnostic capability. The output voltages of all regulators except regulators 2 and 3 can be controlled via the I2C-bus. However, regulator 3 can be set to 0 V via the I2C-bus. The output voltage of regulator 2 (microcontroller supply) and the maximum output voltage of regulator 3 (mechanical digital and microcontroller supplies) can both be either 5 V or 3.3 V depending on the type number. The maximum output voltages of both regulators are fixed to avoid any risk of damaging the microcontroller that may occur during a disturbance of the I 2C-bus. The amplifier diagnostic functions give information about output offset, load, or short-circuit. Diagnostic functions are controlled via the I2C-bus. The TDA8588 is protected against short-circuit, over-temperature, open ground and open VP connectio

PIC16F887 877 programming in C Tutorial 5 LCD Interfacing

LCD Interfacing: In this tutorial i will show you how to interface 16x2 LCD with micro-controller. 16x2 means there are two rows and each row contain maximum 16 characters. For more detail refer to the LCD datasheet, which you are using. Basic Connection: Applies 5v to pin 2 and gnd to pins 1 & 5. Use variable resistor at pin 3 to set contrast. Pins 7 to 14 are the data pins,, used to send/rec data. Pin 6 is of enable; every time when you write to lcd you should have to give high to low, to this pin. pin 4 is register select pin use to give commands like clear, home etc. In this tutorial i will interface lcd in 4-bit instead of 8-bit, so we only required four data pins. Code: Lets write a code that will display the motor status and its direction; it will be fun!!!! Requirements: Design a motor controller circuit using l298 and display its status on lcd. LCD is connected to portb and motor controller circuit is at portd. Required two switches to change motor direction; if both ar

12V to 30V DC to DC Converter circuit Diagram

12V to +/- 30V DC to DC Converter circuit Diagram This is a DC to DC converter for car power amplifier. 12V input generates +30V and -30V output for preamp or power amplifiers. Circuit uses SG3525 IC, Mosfets and switching power supply.
