If there is further reduce in temperature, the PLC sends command to cooler No:1 damper motor to fully close the damper & put off the spray pump & fan motor. Then the PLC will monitors the temperature. So the cooler no:1 damper motor will rotate the damper shaft and when the damper reaches the half closed position, the position is sense by PLC (by micro switch) and PLC sends stop command to damper motor. Lets assume that PLC sends command to cooler No.1 to close its damper to half. So when the temperature begin to drop ( due to ambient temperature or power reduced), PLC send command to coolers to close its damper from fully open to half open. Lets assume the 4 coolers are in service now. This dampers had three position : open, middle & closed. There are dampers installed in each coolers. When the temperature begins to drop, the coolers begins to cutoff one by one ( on first in first out biases ) by sending commands to PLC.

That is, when the temperature is high, the coolers begin to come in service one by one to maintain the temperature in preset limit & vice versa. Cooling system consist of 4 nos cooler with water spray nozzle at top and axial fan motor at bottom, for forced air cooling.

Hench, a cooling system is incorporate for cooling this Thyristor. During AC to DC conversion, this Thyristor gets heated. In this HVDC station, there are Thyristor (SCR) valves bank. I work in a Power Grid where there is HVDC station. Well done friend!!! i understood it very well. Once my project is done I will be more than happy to share my design with you and intend to attribute you in my final code. The DDS produces a stable signal up to 40 MHz and will make a nice lab bench signal source to compliment my home brew function generator. I am not at this time looking to add a display because my goal is to keep the project simple and will set the frequency with an o’scope. I am probably going to use a separate push button since the encoders I am getting do not have an integral switch.

When I get the encoders I will integrate your code into mine. I copied yours and it compiled without error. There were other code examples elsewhere using interrupts but I wanted a version that didn’t use them. Voila! You have exactly the code I was looking for, thank you. Unfortunately there wasn’t much on the Arduino web site about them so I did a search and found your web site. What came to mind was using a rotary encoder to set the frequency. I was originally going to use a compiled robot basic app but I wanted a stand-alone set up, preferably battery powered.

So far I have been able to use it via the serial port. That said, I am designing an Arduino Uno based direct digital synthesizer using a DDS9850 module I got via Amazon. I’m a retired EE and amateur radio operator (call N1ABE) with a lot of experience however, as part of that experience I’ve learned not to reinvent the wheel.

Or you can use interrupts instead of checking the state of the pins in the loop() to ensure that no step is missed. Then it can’t know, which direction it was turned, so the counter will get slightly incorrect.īut you can counter that by checking, which direction it was turned before and increasing or decreasing the counter accordingly by 2. But if you turn it too fast or you do other stuff in your loop() that takes longer time you will miss a step and it will jump from 11 to 00 or from 10 to 01. This works really great if you turn the rotary encoder at a normal speed. Example code (not easy to read but efficient and compact):īool A = digitalRead(pin_rotaryA), B = digitalRead(pin_rotaryB)

To get the full resolution, you have to check every change. This method only uses half the resolution of the rotary encoder as there are four different states per cycle (11, 10, 00, 01) but you only check for TWO changes in each direction (if from 10 to 00 or from 01 to 11 –> counter++ if from 11 to 01 or from 00 to 10 –> counter–).
