  1. GETTING STARTED WITH AUTOMATION BUILDER

    Thank you very much for that information. I will call ABB and hope I have some luck with them 
  2. Hello guys, I hope everyone of you has started 2017 well. I don't have any experience with ABB PLCs but soon I have a project with an ABB PLC and the software Automation builder version 1.2. I ma looking for documentation that will help me get started with the programming basics of this software from scratch. If anyone knows where I can get such documentation, I highly appreciate because I can't seem to get any when I search on the internet. Thank you guys, and Happy new year everybody.
  3. OMRON PLC MEMORY AREAS

    Thank you  Dick Oestreich, That does give me a general understanding. I am used to SIEMENS PLCs and I would relate the two as follows from what I seem to understand; D..........................Data block memory W.........................Local memory H..........................The M memory Correct me if I am wrong, Thanks again.
  4. OMRON PLC MEMORY AREAS

    Hello guys, I have gotten to a level where I can do a few things with an OMRON PLC. However, there's something that is supposed to be basic by now but I still don't understand it, and I will appreciate your help on this . What is the difference between the D, W and H memory areas of the PLC? And in what instances do I utilise each of them for storage of my data? Thank you.  
  5. ANALOG INPUTS AND OUTPUTS

    Thank you Michael
  6. ANALOG INPUTS AND OUTPUTS

    I see, I'll do whatever calculations I need to do before the conversions. Could you be having an example of a project where you've used the PID instruction? It would be of great service to me. Thank you.
  7. ANALOG INPUTS AND OUTPUTS

    That's a little bit crazy. Because when conversions are done from real to integer then you are either truncating or rounding off which obviously affects the accuracy.
  8. ANALOG INPUTS AND OUTPUTS

    Thanks, I was wondering how I was supposed to do that. The next question now is; There are bunches of bits from words that are used in islolation for instance Bits 04 to 15 of C+5 are supposed to be for 2-PID parameter (a). There are other separate bunches of bits. How do I manage to write to only that stream of bits and not the rest of the bits within that word? If anyone has an example of a project where they have used this, it would be of very great help. And the additional question is; do I always have to move the data as word? Because I realize sometimes I need to write floating point values and those would typically need 32-bit address areas, I don't know how that affects the C, C+1, C+2,... addressing order. Thank you.
  9. ANALOG INPUTS AND OUTPUTS

    I am now onto PID control. I have seen the two PID control instructions; PID and PIDAT. However, my challenge with them is: How do I actually set the values for the different parameters? Because the interface of the instruction only shows three parameters yet there's much more to the PID than those three. I read the manual for the PID instructions and it talks about other parameters such as C, C+1, C+2,.... My question is; how do I access and get to set these parameters? Thank you.
  10. ANALOG INPUTS AND OUTPUTS

    Thank you very much guys. Your advice has been so helpful.
  11. ANALOG INPUTS AND OUTPUTS

    I was trying to understand if the analog input cards also have a set maximum (for instance 0-8000). I think I get it that they do have. I f am scaling a 0-1460 rpm output for instance, my zero_point would be 0; Max_Point be 8000; the  Max_Analog_in_INT  be 1460. And then I would take the integer value out of the analog output card (that's when I utilise your Function block). That's what I make of it, please correct me if I'm wrong. The other intriguing question is; Does OMRON have standard function blocks for scaling inputs and unscaling outputs in CX-Programmer? Thank you.
  12. ANALOG INPUTS AND OUTPUTS

    I am not so sure I understand that. I am referring to analog outputs form the PLC this time. For instance if I am sending a 0-50Hz frequency setpoint to a VFD. On the HMI the operator enters a value between 0 and 50Hz. How do I unscale te operator value to a form that the PLC will understand (I imagine that will be in integer format). Kind Regards.
  13. ANALOG INPUTS AND OUTPUTS

    Now I wanna ask about the analog outputs. I am imagining I have to unscale them in some way inorder to convert operator values or automatically generated values from for instance a PID into a format understandable by the PLC. Do you have any suggestions as to how I can go about this? Thank you.
  14. ANALOG INPUTS AND OUTPUTS

    I get it, Thank you very much.
  15. ANALOG INPUTS AND OUTPUTS

    OK, I get it. In that case; does it matter if I am using 4-20mA or 0-20mA?
