I.e I just couldn't transfer from automatic to manual control at the commissioning box. Can anyone advice please. |

Thank you again and sorry for being vague as you mentioned but it was not intentionally indeed. I am trying to apply Fuzzy logic and PID controller on controlling the speed a DC motor on TIA software for academic purpose. So at an earlier level I need to be apple to read the motor velocity through PWM output when the motor is on action. Please see the attached pdf file for the kits.

Thank you guys for your information and yes I recently knew that fuzzy logic on PLC for DC motor is not a worthy project, but unfortunately I have to try it. For the point of using counter as a time based, which type is it HSC or the normal counter?. On other side, in the board I have two points I0.4 & I0.5 (LEDs) that making signals when the motor cut their fields, i.e. when the motor cut any one of them 4 times that makes 1 rotation. So can I use the counter to count the speed using these to inputs I0.4 & I0.5 ? If it is possible please advice. The two LEDs are visible in the attached pic next to the rotor one of them is on and the other of. AttachmentMotor board 1.pdf (535 Downloads) |

Hi guys. Am I the only one that thinks that fuzzy logic can work. ~ okay... so that sounded worse than it actually is. Jeff - My problem is not what is asked. It is that too many of these academic projects are given without any know-how guidance.
We have no idea what the outcome of your project should be. It will be best if you spell it out for us... is it speed control? ...is it position control? ...is it just-get-it-moving-using-fuzzy-logic? You have an impressive board to play with there. Again it will be most helpful to see a schematic of what is connected where.... and what is actually relevant to the project. For homework - see if this helps for background: Share also with us what you know of the S7-1200 and what program languages (C / Java / Ladder / SCL / Ruby) do you know. It is important to establish from which base to work with. w |

Thank you again. I can make the pulses with two timers but this serves fixed duty cycle. So how can I make it with adjustable one? please advice. I found the PLC trainer and the schematic for the motor and they are attached in this post. Regards.. Okod. AttachmentPLC. Trainer .pdf (316 Downloads) |
