Controlling Stepper Motors with RSlogix 500

[yuvraaj]

I am quite new to PLC and have to build a solar tracking system.
I have to move my stepper motor by 15 degrees every hour .
That means 24 steps for 360 deg rotation. I will be using ULN2003 for
stepper motor control.

Please help me out here

If you new to PLC and without strong basic that will be problem during programming.

And you task to rotate SM by 15 degrees.

My short idea,

Use Omron H3CR-F and IC Timer 555 reshape with IC Schmitt trigger 74HCT14
Inject to ULN2003.

You will not spending on PLC Hardware and Software.

But using PLC is compulsory you have no choice to learn faster.

Thanks

Thanks Osman !
But project is PLC based and I hv tried 74194 with ULN 2003 and clock .
Anyways thanks very much I will try learning ladder programming.

Thanks Again !

Extremely thankful for the link

The inputs of the ULN will need some resistors, as max voltage is 5
output of PLC is 24 volt so a resistor of 5 kohm and 20 kiloohm are needed for each output.
On the PLC a stepping with 1 or 2 outputs on.
just shift the byte use 17 as shiftnumber.
use the RTC for timer.
