  1. S7 200 SEG INSTRUCTION

    This is really easy and very helpful. Thank you very much.
  2. S7 200 SEG INSTRUCTION

    Hello guys. We are trying to replace a S7 200 PLC at our station with S7 1200.  We are reading the program on the S7 200 and recreating the same on the S7 1200. However, we have encountered the SEG  instruction used several times in the S7 200 (microwin) program. And the SEG instruction is not available in TIA Portal (we are using TIA 11) for the S7 1200. We have tried to read the s7 200 system manual but the explanation of the instruction is not sufficient to help recreate it. Could anyone know how we can create our own equivalent of the SEG instruction? If anyone has the SEG instruction already created as a program, it would be very helpful. Thank you.  
  3. S7 200 SEG INSTRUCTION

    Hi guys, I managed to get the instruction in STL; I have attached it in the Screenshot down. However, now the challenge is, I need to implement it in SCL since the later versions of TIA do not support STL any more.  If any one knows SCL and may help us to convert it, it would help us a lot. Thank you.
  4. TRANSFER FROM NS15-TX01B-V2

    Hello Forum,We have a NS15-TX01B-V2 at our Plant in Uganda which we are using with a CJ2M PLC. We want to take backup from the PT to PC using Ethernet but we have not succeeded yet. We have consulted the manuals but they are not very elaborate. Someone here may know the step-by-step procedure we can  follow. to achieve our goal. We shall be very grateful.Thank you.
  5. TRANSFER FROM NS15-TX01B-V2

    Hello IO_Rack. Thank you for your reply. I do not know the comm settings of the NS. I could not find a way to read the IP address of the NS. I will try again to autodetect the NS Ip addrees and follow the two timeout sequence and hope that's the catch. Thank you. Kiiza.
  6. Hello guys, I am looking for Cx-One trial version and I am interested in version 9.4. Does anyone have a link where I can download a copy from? Thanks in advance.
  7. Hello guys, hope you are well. I have with me KOYO PLC C0-02DD1-D. I have programmed it successfully. However, I do have a challenge with it's digital outputs. I expect a voltage of 24Vdc from the outputs but I am instead getting a voltage of 12Vdc. Even the 12Vdc I measure at the outputs looks fake voltage because whein I use it to energize 12Vdc relays, they don't get energized. I appreciate your help. Thank you very much.
  8. KOYO PLC C0-02DD1-D OUTPUTS

    I will try that out. Thank you very much.
  9. CX-One v9.4 TRIAL VERSION DOWNLOAD

    I downloaded v4.27 but for some reason it can not install. Anyone who knows if I have to follow a particular procedure?
  10. CX-PROGRAMMER MOVE INSTRUCTION

    Now I understand. Thank you very much.
  11. Hello guys, I need help. I have an OMRON PLC; CJ2M series which I am not very familiar with. I need to do comparisons, but I see that do that I can't just compare with a value. It looks to me that I have to store the value I need to use to compare in a memory address and reference to the memory address for my comparison.  Is it possible for me to compare using a value and not have to first go through a memory address? Is there a way to use the instruction to store the value in a memory location ? Or do I specifically have to use CX-Designer for me to wrote the value to a memory location? Thanks in advance.
  12. CX-PROGRAMMER MOVE INSTRUCTION

    I have attached two Pictures. In the first picture (OMRON), everything is OK. In the second picture (OMRON2), the instruction remains red because I was trying to compare direct with a value of 105. Does OMRON not allow that?
  13. GETTING STARTED WITH AUTOMATION BUILDER

    Thank you very much for that information. I will call ABB and hope I have some luck with them 
  14. 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.
  15. 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.  
  16. 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.
  17. ANALOG INPUTS AND OUTPUTS

    Thank you Michael
  18. ANALOG INPUTS AND OUTPUTS

    Hello guys, I am happy to be on this forum. I am just starting up with OMRON PLCs. I have been programming SIEMENS PLCs for the last three years. I am quite comfortable with the boolean logic. However, I am struggling with the analogs. I'm looking for an instruction that will help me bring in and scale analog inputs and I am wondering if I'll need to unscale the analog outputs as I send them out. I have tried the SCL instruction but it does not seem to do for me what I need. i need to get a signal wired to the input card and convert it to a maningful value. Plus, advice about how to address analog inputs and outputs would be very helpful to me. Thank you very much, I appreciate.
  19. 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.
  20. 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.
  21. 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.
  22. 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.
  23. ANALOG INPUTS AND OUTPUTS

    Thank you very much guys. Your advice has been so helpful.
  24. 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.
  25. 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.
