How can I establish connection between DirectSoft Programming software and LookOut

kone — Tue, 17 Oct 2006 19:29:02 GMT

Hi,

I am working with a DL06 PLC. I am trying to a develop a LookOut Direct HMI for this tainer. I would like to know if there is any option in LookOut where it allows me to run small parts of PLC code along with HMI so that i can toggle discrete output. To be more speicifc i have X0 - 16 input bits and C0 - 16 status bits. I have to develop a logic in PLC programming so that the status bits toggels Y0 - 16 outputs on the tainer. So can you please let me know if there is any way of establishing communication between LookOut HMI and DirectSoft 32 PLC programming software.

Thanks

regards

Koneru

Lookout or LookoutDirect?

Its LookOut Direct HMI Software. Can you please help me with this?

Thanks,

I'm no expert on LookoutDirect.

Actually, LookoutDirect is not NI's product. As far as I know, there are some new objects for the connection to DIrectSoft.

Maybe someone else here can help you.

I am not sure if I understand the question fully. I am guessing you would like LookoutDirect to toggle some bits -- in which case you would just write to these bits from LookoutDirect. This would work fine as long as the PLC isn't overwriting these.

Please post back with more details if I have misunderstood your query.

Ya, now im directly establishing connection between 'C' bits and HMI inputs and it works !

Thanks a lot for your support !

I have one more question can u help me convert inputs from decimal to BCD. I have decimal input on the HM screen that has to be converted to BCD when fed to the PLC. How can i do this?

To convert to BCD with LookoutDirect, just add the :B modifier after your object (e.g. DL250.V2000:B=Pot1) as described in the "Getting Started" manual (Appendix B of the current one).

Thanks for the answer but my problem is i need to turn on particular set of bits for each value of decimal number. So any idea as to how can i do this? Please help.

Kone,

Have you tried mathematics.

I use something like:

ADec2Bcd = sum(mod(000,16),mod(trunc(000/16),16)*10,mod(trunc(trunc(000/16)

/16),16)*100,mod(trunc(trunc(trunc(000/16)/16)/16),16)*1000);

Simply replace the 000 with the value to be converted, can be a numerical object.

Hi,

Im not sure if i understood that right. I have attached my control panel with this e-mail.

Please have look at it. Now what i need to do is for each value of thumbwheel i need to

turn of a set of inputs.

For example when thumbwheel v alue = 1, bits Y110 and Y113 should go high

and when thumbwheel value = 2, bits Y114 and Y115 should go high and so on..

I have thumbwheel values from 0 to 9. So how can i insert expression for the thumwheel to accomplish this task?

When i go to Insert -> expression, it gives me a separate display for each value and i dont want this to happen.

Please help me.

Thanks a lot !!!

regards

Kone,

I can't look at your file, but a possible option is to create a connection to DL06's V40504 (alias VY100 … 16 bits for V100-V116) and use an expression with the lookup/choose function.

choose(thumbwheel.value+1,?,2304,12288,?,?,?,?,?,?,?)

For 0:?

For 1: 0000 1001 0000 0000 =0x0900=0d2304

For 2: 0011 0000 0000 0000 =0x3000=0d12288

etc.

If you're using C bits in the PLC program to control your Y outputs, then you just have to change the connection to the appropriate Vmem location (V40600-V40677).

… but I would stick to writing as decimal not BCD.

Good luck.

I have used a nested NIF function to make sure that certain values output the correct value. An Example is:

ConvWidthSvRawW= nif(ConvWidthSvW=4.10,1040,nif(ConvWidthSvW=4.60,1120,nif(

ConvWidthSvW=5.10,1296,nif(ConvWidthSvW=8.20,2080,nif(

ConvWidthSvW=8.70,2160,nif(ConvWidthSvW=9.70,2416,nif(

ConvWidthSvW=10.20,4128,nif(ConvWidthSvW=16.40,5696,nif(

ConvWidthSvW=16.90,5776,nif(ConvWidthSvW=17.40,5952,nif(

ConvWidthSvW=17.90,6032,nif(ConvWidthSvW=18.40,6208,nif(

ConvWidthSvW=18.90,6288,nif(ConvWidthSvW=19.40,6464,nif(

ConvWidthSvW=19.90,6544,nif(ConvWidthSvW=20.40,8256,(sum(mod(

ConvWidthSvW*100,10),mod(trunc(ConvWidthSvW*100/10),10)*16,mod(

trunc(ConvWidthSvW*100/100),10)*16^2,mod(trunc(ConvWidthSvW*100/

1000),10)*16^3,mod(trunc(ConvWidthSvW*100/10000),10)*16^4))))))

)))))))))));

You may need to do the same thing for your values. Depending on how many you have you may end up with a very long expression.

Thanks ! Now my system works fine.

I would like to ask one more question:

I am using a pot object for my thumbwheel and it has a increment button and decrement button. The range of my thumbwheel is from 0 - 9. If i press the increment button after 9 it does not do anything. I would like to change it so that the range becomes 0 after 9. For instance if we press the increment button after 9 it should go like 9,0,1,2,3....9,0 and for the decrement button after 0 it should be like 0,9,8,7,....0,9.. Can this be done with LookOut Direct? I have tried using expression like

if(pot.value>9, 0, pot.value) -------- for increment button, but its not working.

Can you me any suggestions to get over my problem please!!!

Thanks again
