Hello , can someone explain to me what the difference between the reset ( RES ) and clear ( CLR) in RSLogix software? Please respond ASAP

CLR sets a numeric value to zero. RES causes a structure - such as a timer or counter - to return to its start condition.

grateful for the response , b_carlton .

But there is a doubt

Example : If I enter the address of a counter in the CLR and RES as C5: 0.PRE , both will reset the preset my counter.
What if I put the address as : C5: 0.ACC the CLR and RES will also perform the same operation .

So I am not able to understand the difference between them.

You can't RES C5:0.ACC.  Try putting it in then verifying the rung.  It will tell you the address must be specified to the element level.  In the same sense you can't CLR C5:0, it must be specified to the word level.

You could think of a RES as a CLR of the ACC and an OTU of the CU, CD, DN, OV, UN, and UA bits all bundled together.

Você não RES C5 pode: 0.ACC. Tente colocá-lo em seguida, verificar a degrau. Vai dizer-lhe o endereço deve ser indicada ao nível do elemento. No mesmo sentido, você não pode CLR C5: 0, deve ser indicada ao nível da palavra.

Você poderia pensar em um RES como um CLR do ACC e um OTU da CU, CD, DN, OV, da ONU, e pedaços UA todos juntos.

ok.. thanks

And this case ?

 

If I enter the address of a counter in the CLR and RES as C5: 0.PRE , both will reset the preset my counter

You can't RES C5:0.ACC. this is where an exercise works best for understanding. Put it in your program and tried to verify it then look at the error it comes up with.

I 'm not the program with me now , I'm just with LogixPro simulator, and in it I can reset the RES using C5: 0.ACC do not know if the rSlogix is so , I think so as you 're talking about. but now my doubts is to address C5: 0.PRE for both RES and for CLR , using in both the same thing happens , so do not know the difference . could you explain me? thank you

Why don't you install RsLogix 500 on your PC along with LogixPro.  LogixPro is a very good learning tool but there are some differences that RsLogix 500 along with Emulate will help you understand.
