Design a control for four electric motors. Motors 1, 2, and 3 are to be controlled separately. When any one of the three starts, motor 4 is to start. Motor 4 can also be started independently of the others. If any motor reaches an overload condition, it will shut down all of the motors. In addition, there is to be a master start-stop switch (momentary) to make it possible to manually shut down all operating motors at once. The master start switch energizes the control circuit after which any particular motors is started individually. Report your circuit in ladder diagram form.

To create a delay using the Output Compare Channel 6, we add a number of cycles (CCOUNT)to TC6 and then wait until TCNT is equal to TC6. This happens when TLFG1(6) =1. Assuming an E-clock of 24 MHz: Complete the following table in order to generate the given delays:

Draw a breadboard fritzing diagram that connects a HT12D decoder, 433 MHz Receiver, L2930 Motor Driver and 2 DC motors that allows for bidirectional proportional motor control.

a)Constract the use of electromechanical relays against a PLC in the implementation of an automatic solution, giving the merits of using the PLC.
b) Two digital outputs y and z need to controlled as follows:
Y turns on if inputs x1 and x2 are high or if input x3 is low and input x4 is high. Y stays on for 7s and then turns off, while simultaneously setting the output z to high. Z stays high for 5s, following which the sequence is repeated. The process is started by pressing a start pushbutton and is stopped by pressing a stop pushbutton.
Draw a ladder logic diagram to program a PLC for this application.

Recall that a float is stored in the following format:

±sign 1.mantissa • 2^exponent?127

where sign is 1 bit, exponent is 8 bits, and mantissa is 23 bits. Write a C function that accepts an int parameter and returns a float represented by the bits in the int. The 32-bit integer is organized as 1-bit sign, 8-bit exponent, 23-bit mantissa. For example, 0x3F800000 represents 1.0 because the sign bit is 0, the exponent is 127, and the mantissa is all 0’s.

It has to be a proper c executable code.Please help.

Three balanced 3-phase loads are connected in parallel. Load 1 is Y-connected with an impedance of 400 + j300 ? per phase, load 2 is ?-connected with an impedance of 2400 – j1800 ? per phase, and load 3 is absorbing 172.8 + j2203.2 kVA. The loads are fed from a set of distribution lines with an impedance of 2 + j16 ? per line. The magnitude of the line-to-neutral voltage at the load end of the line is 24?3 kV(rms).
