==Description==
 +
The PLC LED controller is part of the [[Sphere lab|Auditory Sphere Lab]] and consist of a modular PLC from the Panasonic FP2 series. It controls the Red and Green LEDs in the setup. See [[LED specifications|here]] for LED specifications.
 +
 +
==How does it work==
 +
The PLC LED controller  is programmed with 'FPWINPRO 7' PLC programming tool of Panasonic. The program can be found [https://gitlab.science.ru.nl/marcw/biofysica/-/tree/master/experiment/sphere%20Panasonic%20PLC?ref_type=heads here]. The program starts automatically when the PLC is switched on. The program controls 256 relay outputs for switching 128 red and 128 green LEDs on or off. The intensities of the LEDs are controlled by Pulse Width Modulation (PWM).
 +
 +
From Matlab you can sent up to 16 LED configurations to the controller. With a trigger pulse you can let the LED controller know that it should present the next configuration. The LEDs are numbered 0 to 127 and there are red and green LEDs. With the test buttons on the door of the PLC cabinet you can switch on all red or green LEDs at once. A configuration specifies the ON or OFF state for all red and green LEDs with two arrays of 128 bits. The intensity of the red and green LEDs are not individually addressed, but set for all red or green LEDs at once with one number between 0 and 50.
 +
 +
==How to use==
 +
You basically have to do two things:
 +
*Specify the configurations (LED patterns) in matlab and sent it to the PLC.
 +
*Specify triggers in your experiment code in matlab.
 +
 +
A Matlab example:
 +
 +
1:  n = 8;
 +
2:  s = ledpattern(n);
 +
3:  for i=[1 3 5 7]
 +
4:    s(i).set([1 3 5],'r');
 +
5:    s(i).set([2 4 6],'g');
 +
6:    s(i).intensity('r', i);
 +
7:    s(i).intensity('g', i);
 +
8:  end
 +
9:  leds = ledcontroller('fp-web2.local');
 +
10: leds.write(s);
 +
 +
*In line 1 the number of ledpatterns is specified.
 +
*In line 2 a ledpattern array is created with n ledpatterns
 +
*Between line 3 to 8 the odd numbered patterns are looped through.
 +
*In line 4 to 7 a collection of red and green LEDs are set and intensities are assigned to the red and green LEDs.
 +
*In line 9 a led controller object is created with the name of the Ethernet connection.
 +
*In line 10 the ledpatterns are written to the ledcontroller.
 +
 +
After running this program the PLC controller can be triggered. Upon receiving a first trigger pulse the PLC will present the first ledpattern. The second trigger will display the second ledpattern, but since nothing is written to s(2) all LEDs will be off. The next trigger will display the next ledpattern etc.. The end result is that the LEDs will go on and off each time with a higher intensity.
 +
 +
You can find the Matlab code and examples [https://gitlab.science.ru.nl/marcw/biofysica/-/tree/master/experiment/led?ref_type=heads here].
 +
 +
==Specifications==
 +
*Panasonic PLC
 +
*FPWINPRO 7 sofware
 +
*Response time to trigger < 1.3 milli sec
 +
*2x128 output channels
 +
*5 pins Binder connectors for LEDs
 +
*Test buttons for Red and Green LEDs
 +
*BNC connector for input trigger
 +
*Ethernet connector for communication
 +
*The LEDs that are used in all the labs are [[LED specifications|Bivar 5BC-3-CA-F LED]].

Inside the PLC cabinet

Description

The PLC LED controller is part of the Auditory Sphere Lab and consist of a modular PLC from the Panasonic FP2 series. It controls the Red and Green LEDs in the setup. See here for LED specifications.

How does it work

The PLC LED controller is programmed with 'FPWINPRO 7' PLC programming tool of Panasonic. The program can be found here. The program starts automatically when the PLC is switched on. The program controls 256 relay outputs for switching 128 red and 128 green LEDs on or off. The intensities of the LEDs are controlled by Pulse Width Modulation (PWM).

From Matlab you can sent up to 16 LED configurations to the controller. With a trigger pulse you can let the LED controller know that it should present the next configuration. The LEDs are numbered 0 to 127 and there are red and green LEDs. With the test buttons on the door of the PLC cabinet you can switch on all red or green LEDs at once. A configuration specifies the ON or OFF state for all red and green LEDs with two arrays of 128 bits. The intensity of the red and green LEDs are not individually addressed, but set for all red or green LEDs at once with one number between 0 and 50.

How to use

You basically have to do two things:

  • Specify the configurations (LED patterns) in matlab and sent it to the PLC.
  • Specify triggers in your experiment code in matlab.

A Matlab example: 

1:  n = 8;
2:  s = ledpattern(n);
3:  for i=[1 3 5 7]
4:     s(i).set([1 3 5],'r');
5:     s(i).set([2 4 6],'g');
6:     s(i).intensity('r', i);
7:     s(i).intensity('g', i);
8:  end
9:  leds = ledcontroller('fp-web2.local');
10: leds.write(s);
  • In line 1 the number of ledpatterns is specified.
  • In line 2 a ledpattern array is created with n ledpatterns
  • Between line 3 to 8 the odd numbered patterns are looped through.
  • In line 4 to 7 a collection of red and green LEDs are set and intensities are assigned to the red and green LEDs.
  • In line 9 a led controller object is created with the name of the Ethernet connection.
  • In line 10 the ledpatterns are written to the ledcontroller.

After running this program the PLC controller can be triggered. Upon receiving a first trigger pulse the PLC will present the first ledpattern. The second trigger will display the second ledpattern, but since nothing is written to s(2) all LEDs will be off. The next trigger will display the next ledpattern etc.. The end result is that the LEDs will go on and off each time with a higher intensity.

You can find the Matlab code and examples here.
