  1. Square Root Instruction

    Sleepy Wombat, thank you for your help. I have tried, and everything works.
  2. Square Root Instruction

    Sorry for the poor picture. Hopefully, the next one is better.
  3. Square Root Instruction

    Based on description of the SQRT (466) instruction (manual W340 page 550) created very simple ladder diagram. Rungs 1, 2, and 3 work O’K. I can see correct numbers in the instructions themselves and in the memory cells. The last rung gives me strange numbers. I tried to change 621 to 620 – no result. Using “Toggle Watch Window,” I set all the numbers to “Real (Floating Point, Double Length)" - no result. I do not need very precise value, integer is good for me, but the numbers I am getting are totally wrong and weird. What am I doing wrong?
  4. Strange ranges for analog input modules

    Mine wasn’t a ghost. I have found what was wrong; my transmitters are all messed up. They are more than 10-year old. Now, I am having troubles with square root instruction. CX-Programmer is not simple thing to deal with. May be later, in another topic, I will ask couple questions about it.
  5. Strange ranges for analog input modules

    What bit? Where did it fall? How often does it happen? How to recognize and fix?
  6. Strange ranges for analog input modules

    Strange things are happening with my Omron. Today, using the same equipment, I have got the positive result; everything is working as it is supposed to (I mean ranges). I did not change anything since Saturday. What is going on???
  7. Strange ranges for analog input modules

    After I got these strange ranges, I disconnected my transmitters and applied just 4mA to 20mA signal using a potentiometer and a ammeter. So signal for sure was in this range 4 mA to 20mA.
  8. Strange ranges for analog input modules

    Hi PdL. Yes, I did. I was not sure about my transmitters; they are old. So I decided to apply just 4 mA to 20 mA signal. And I have got the results, I described in my previous post. Yes, the manual tells different, it is why, I am asking people, who have worked with these modules before. I have no idea, why I am getting such strange results.
  9. Did anybody work with remote analog input modules DRT1-AD04 and DRT1-AD04H? I am using those to read flow and level signals (4 to 20 mA). Omron representative told that the module output for this range is going to be for DRT1-AD04 - from 0 to 6000 in decimal, and for DRT1-04H – from 0 to 30000 in decimal. The program, which is based on these ranges for both modules, did not work. After I tested the modules by applying the input signal 4 to 20 mA found strange ranges. DRT1-AD04 gave me for 4mA input signal value 65535 and for 20 mA input signal 5800 (both in decimals). DRT1-AD04H gave me for 4mA input signal value 32767 and for 20 mA input signal 28900 values (both in decimal). If somebody worked with these modules before, and could confirm that the values are correct or very close to what is supposed to be. Or may be I am doing something wrong. It is good to know. If it is important, I am using CJ1M-CPU13 and CJ1W-DRM21 Master module.
  10. MAD42 analog module

    Thank you, PdL. To tell the truth, if not your help with CIO 2010.0/1, I would have spent tons of time trying to figure it out. The manual wasn’t very clear (very unclear) about this key moment.
  11. MAD42 analog module

    It is working!!! Thanks everybody for help. You were right, the problem was in energizing 2010.0 and 2010.1 bits. Now it is giving me what I want.
  12. MAD42 analog module

    PdL, I do not understand. On page 313, there is nothing about CIO memory area, but I will try today. It is strange and confusing manual. ECSI is right, if I have to set up CIO 2010.0 and 2010.1 to 1, what is DM20100 for?
  13. MAD42 analog module

    PdL, one more question. If I decide to go with voltage output -10V to +10V signal settings, my table has to be set up as on the picture? Just want to be sure.
  14. MAD42 analog module

    The morning coffee is my only hope. Your table is exactly what I did except the last word (20135) I‘ve tried both #3 and #5. Both did not work. Looks like Monday is going to be busy. Thank you, PdL, at least now I know that I am on the right track; otherwise, there is always doubt.
  15. MAD42 analog module

    On the picture, it is why I used #3 in the word 20135. But I really tried #5. Did not worked. When I set the value of the word 20135 I used “2” (binary) option of the table. But I looked in the hexadecimal mode too. The value was correct. Maybe tomorrow, I will use MOV(021) command to be sure about it.
