Hi Guys, Just wanted to update you, My program is working Now and I got the expected output signal. what I missed was activating the output.  Just turn ON the bit "Ch1_ConvCMD" and I got the signal.  anyway, thanks a lot for your support.

Hi, I need your help/ suggestion to configure CJ1W-DA021 for 1 channel output connected to Digital Regulator using Sysmac studio. I have already added it to the CPU rack see the attachment. how can I determine the appropriate analog out values to have the digital regulator deliver the correct pressure? how can I calculate the set value base on what?? I read the Manual but still stack, I do not understand how to calculate it to give me the desire digital output (pressure in PSI ) to my regulator  This is the first time that i program analog out put therefore I need your advice/step to help me finish my project. appreciate your response in advance. Noor 

did i miss anything in the configuration of the module??

I have already connected the voltmeter to the output channel of the module but its shows me 0 v on the channel. however i am sending values, which i can read it in the watch window 

Hi Guys, I downloaded the program to the cpu, but the regulator did not show me any changes its just read one value, while the output in the software change. I really do not know what is the problem?? did I miss anything in the configuration?? or its hardware error

Yes you are right, I just checked it..so why i do not have this function the?? 

Yes you are right, I found it in help instruction, but unfortunately we are using Trial version 1.12, so it does not have this function. Thanks anyway for mentioning that.

I think my program is working, I will configure the module on Saturday and download the program to cpu and will keep you posted. hope everything will work fine. many thanks to you guys (Crossbow & Michael) for your feed back. I am very happy to be member in this forum. Thanks again for your support.

Thanks Michael for your clarification, Actually I have already done this part, and I calculate my value using the above equation but the data type of my value is LREAL, and the out put channel data type is Int. question 1 is how can I get float value if its data type INT?? Thanks

Hi again, Now my question is how can i send the scaled value to the output channel to give me the final output ??  I used this equation to scale my output values  A= U * 4094/(H-L) where  U : is the engineering unit, H (max range which in my case 100PSI) , L (min=0PSI). and A: is the Analog out put value. thanks again.

Thanks Crossbow, really appreciated.

Hi, I read through your post, and have question regarding the array, can you explaine to me how can we initialize array in sysmac studio??  thanks

Hi Crossbow, Thanks for your answers, I only do PLC Programming on and off and have never done programming analog stuff therefor I need a pointer in the right direction. We have been asked to add digital air regulator to our xpleater machine. I am using sysmac studio with the CJ1WDA021 this module has 2points analog outputs to control the digital regulator measured pressure in psi. Simply, PLC will calculate the necessary tension pressure. This will be the base multiplied by one of two constants. This pressure value will be converted to an appropriate analog output value which will be sent to the analog output module. I have added the module to the cpu rack, and did the configuration as you suggested from the right side I used 1-5V (4-20mA) output signal range. The set value is the number between 0-4000 BUT HOW CAN I FIGURE THIS NUMBER base on what? Another question, how can I determine what the appropriate analog out values need to be to have the digital regulator deliver the correct pressure? Thanks again for any support you can provide.

Thanks Crossbow..

Hi Admin, Thanks a lot for you prompt reply, I will move the post to the Sysmac studio. on the other side, I read the CJ1W- DA021 Module manual but still stack, I do not understand how to calculate the set value base on the graph which I attached. for output range (1-5v) 4-20mA at 1 the output will be 0 and at 5v the output will be 4000. is the set point the average ??in AB SLC500 i used to use SCP SCALE WITH PARAMETER WHICH I insert the min and max input as well as the min and MAx scale. here I do not understand the set value?? I would greatly appreciate your talents and support.

Hi, I have the following error keep showing up as showing in the attachment. how can I get rid of this fault? any suggestion? The wiring connection all right and connected properly Thanks, Noor
