  2. HMI user

    Hi! I would like to ask your help. I have a problem with an allen bradley touch panel. I would like to know which user is active. Like maintenance, administrator... Is there any dedicated tag to decide and  to convey it toward the plc (also ab). If there is none. Can anybody suggest an alternative solution ?  Thanks ahead in advance. 
  3. Convert ASCII to text, Studio 5000

    @BobLfoot  🙇 🙇  Thank you to fixing my poor explanation.
  4. Convert ASCII to text, Studio 5000

    Hello,    Create a new tag. The type has to be string. The string datatype have 2 kind of tag, the data and the length. Move the number how long do you need. Also when you create the datatype set the style to ascii.   I guess thats it. If you want I could send you an example ladder diagram.
  5. GP PRO proface programing

    Hello guys,  Can anyone help me about how to make a growing circle with proface program :). I would like to control it by a real tag or so on. Like if the real tag is getting bigger the circle has to be bigger too between a range. Unfortunatelly I didnt find any solution for this yet, maybe you guys are more experienced and someone could help me. Thanks ahead. 
  6. Measurement problem

    Hi guys! I need to measure a sheet thickness. The sheet is going through between rolls. As the sheets thickness changing the rolls getting rise or descend. I have an ultrasonic sensor. My problem is when the thickness is changing like From 1 mm to 2 mm the ultrasonic sensor signal is not changeing in a straight proportion. The sensor working well around at 2.5 mm. I tought about how to calibrate it correctly. If I put first 0.2 mm sheet then i not it down the value of the sensor then put 0.4 mm sheet And so on....and making little sections like how much is the sensor value and decide by my calculation. Do you know anyone a better solution for this ? Also you guys do you think it will work ? I should write the program in rs logix 5000.  Thanks in advance any idea or tips.  
  7. Powerflex 525 single phase

    Hi ! I have a powerflex 525 inverter. I have three phase motor. It is possible to make running the motor like this? If yes how ? Should I change some parameter in the inverter ? Thanks in advance. 
  8. Dispersion of an array

    Hi Guys. I have a trouble to determine the dispersion of an array. Like I have an array what have 1000 elements. I need to know the dispersion of the numbers. I checked but I didnt find any instruction for this. Im using RS Logix 5000. Can someone pls help me out ?  Thanks in advance.
  9. Powerflex 70

    Hi Everyone! I need some help with configuring an inverter. The inverter type is powerflex 70. How can I set the next parameters. It should be work with two speeds.  First:  around 40 Hz.  Second around 10 Hz.  I think first I need to decide the direction, So I need two digital input for forward and reverse. Then I need plus more digital input, one for the high speed and one for the low speed. I guess I have connect dc 24 V too. I just dont know where should I connect this signal. I didnt find the properly manual. Do I forget something ?  Can anybody help ?  Thanks in adnvance!
  10. RSLINX in excel

    Hi Guys! A have a problem with Excel and RS linx. I belive the communication is good. I just need a few tips, especially with excel. I have about 3000 dint value, and aI dont know how to put them in excel at once. Not one by one. THis is my first question. You can see the link: =RSLINX|MC!'Database_fifo[0].Motor_rpm, L1,C1' the next one is =RSLINX|MC!'Database_fifo[1].Motor_rpm, L1,C1' and =RSLINX|MC!'Database_fifo[2].Motor_rpm, L1,C1' and so on. I dont want to write the numbers like 3, 4 ,5 ...2560... So I hope you guys get it, sorry for the bad explanation. For this problem maybe exsiting some macro or something like that, I dont know. The second: there is some dint what is in decimal style, but acutall they are ascii, I know how solve that, with the char function, but I dont know how to collect it. Like on the picture, there is the numbers what I read from the plc, like 82 equal to R. But I want to see them in one cell. Like RKBF-355, I want them in a same cell. Unfortunaltely I cant solve it. At least until now, and I hope somebody know it by memory.    Thank you in advance!  
  11. Kinetix 6000 servo MSO error

    Hi Guys!   Anybody Can help me ? I have a kinetix 6000 servo, and that axis dont want to go in home position. There is an MSO instruction, but the ER bit is active.  What should I do ? What would be the problem?    Thanks in advance!
  12. logix 5000 array

    Thank you! I have a question about this. First of all, I need to this in ladder logic. I made the GSV, its work properly. But how should I fill the array, as you showed on the pic ?  Should I make a two-dimensional array, or need I an UDT at all events? Sorry, im slow..... :) haha THank you again. 
  13. logix 5000 array

    Hi Guys! I have a problem with array filling. I use rslogix 5000 software. I have to save the timestamp sometimes. I can save it with GET instruciton. Its a dint array which have 7 elements (year, month, day....and so on),  But my problem is I dont know, how can I solve that, they are in a bigger array. So like an array within the array. Idk it is possible ? I hope you know how I mean.  So I have 7 dint value in one array, and I want 1000 array for this. How can increase the position of the array number ?  Can anybody help me with that ?  Thank you in advance.  
  14. RFID + Proface

    Hi Guys! Is there anybody worked already with Proface panel and RFID reader ? Can anybody help me with that ? Even it is possible to use RFID reader on a Proface touch panel ?  The software what I use is RSlogix 5000 and of course, GP-PRO for the proface panel. Thank you so much for your answers.
  15. pid tuning

    Hi there! I have a problem with a process. The bottom line is I have a quite big asynchronous motor (about 110kw), with this motor I would like to fill a pool. There is a sensor that monitors the level. Im setting the PID for the motor control, it seems to be good, but unfortunately the fultuation is very big, however the level is perfect. I send a 4-20 mA signal to the inverter. Actually, it is almost everytime changing. I think it is not good for the motor. the changing scale is between 100 and 600 rpm ... What do you guys think ? Can this cause early motor or inverter failure? I had a thought, I did that I was doing an average and sent the current process data every 3 seconds. It causes that, the motor rpm 100 or 600 rpm.. nothing else, and change it about every 3 or 6 seconds,  because of te too much error I think.  How can I solve the this problem. The material runs out evenly from the pool, but the control variable is still bouncing. I monitored the process variable and the control variable too and the error too. I noticed that the output only changes when it is very close to the setpoint. for example the setpoint is 5000. And if the process variable is 4950 then the output is 100%. and if the process variable is 4992 then the output is about 67% but, the if the process data is 5010 then the output is 0%.   I'd expect that, for example that if the process variable is 2000 then the output is will be 100%. but the process data is 4000 then the output will be 50 % ... and so on.... so I hope I can find a permanent output value.  I dont know, maybe I made some mistake.... pls help me in this situation. Thank you.
