  1. Temperature controling with module

    Hello to everybody! This time I need to make a program to control temperature ... Some help? I don't know how to use an analog module, I'm just starting to working with them. The PLC I have a FX3u-32MR/ES (Mitsubishi), and I have the modules; FX3u-4AD-ADP and FX3u-4AD-PT-ADP for temperature measurement. PLEASE HELP? Have a good day!
  2. i need a example code for position control of MR-J3-20A with QD75D4 as intelligence module. and i want to see the parameter if possible  
  3. Just wondering if I need to set up two Motion Groups to specify the direction of travel along 1 AXIS? (Forward and Reverse) If not, how do I specify direction when using motion instructions (specifically MAM) with incremental motion. 
  4. EMS provides low cost analog sensors useful for PLC analog inputs. For example the $25 temperature sensor (+/- 2%) is a useful and inexpensive way to monitor for an over temperature condition in a panel cabinet. emssensors.com AC voltage and current transmitters can be a useful way to monitor motor performance. Even the sound level sensor can be a good way to generate an alarm condition for a bearing failure.
  5. Hello, I'm new to this forum and PLC world in general (especially to Mistubishi PLCs). I have a task in which I need to synchronize servomotor with another motor that runs conveyer (servomotor needs to stamp a label on a foil on a conveyer), in GX Works3. Servo motor is run by Simple Motion module. I need general tips on how to make pulses from encoder into something useful that can be used to send data to Simple Motion module. I need high speed counter to count pulses (never actually did this, I got this from manuals), how would I, for example, get speed out of it? Number n pulses, divide it with time it took to get to n pulses? How would I make Simple Motion to make servomotor on his Axis #1 to rotate at same speed?    
  6. We are replacing the Old hardware from PLC to new Control logix hardware. wondering Application of IEC-61508 and IEC-61511 compliance in this brown field project. Any Thoughts ??
  7. We have a Panelview Plus 600. One of our panels is labeled "Motor Control," in charge of turning on/off different pumps. The problem is while the system is running, clicking the on/off button will not turn any pump off. When the system is shut down, the pumps can be turned on and off but not when the system is running. I'm trying to shut off one pump without shutting the whole line down. Any help is appreciated. Thanks.

  10. PCS7 with S7-410 for Dummies

    I just need to understand a little bit more about the PCS7 architecture, if someone could point me to a document or a video or something, or just give me a few sentences to break it down it would be greatly appreciated. The reason being, we have a quote that we are working on for a customer over seas and are being told to quote our equipment with an S7-410 PLC.  I am very unfamiliar with Siemens in general, but completely unfamiliar with the PCS7. Our equipment is typically if not almost always stand alone equipment that communicates discretely to the rest of the facility.  Our equipment is not part of a process line, but rather feeds the process line equipment what it needs to perform its operation. I have been led to believe that the S7-410 PLC must be part of a DCS, so it does not seem like the correct fit for our equipment.  I just want to confirm this and learn a little bit more so I can explain to our sales folks and ultimately the end user why it is the wrong option for us and our type of equipment.   Thank you!!!

  11. Hi Everyone, I have a PowerFlex 525, in Velocity Mode with a Encoder Card "25-ENC-1". We are controlling this drive via TCP/IP with a 1769-L32. Through the PLC if I try to toggle the Bit for "Pos Redefine" in A560 [Enh Control Word] it instantly turns back to 0. But through the Parameter List Editor I am able to toggle A560. For My function I need to have the drive in Velocity Mode, If I change the drive to Position Mode I am able to toggle "Pos Redefine"   Any Thoughts would be great      
  12. Hi guys, been using this site for a long time, it has come in handy alot. However I have recently taken on my first servo project, heres an overview of the project We have a filling machine that has a separate dosing system to the filler head. It used to keep the dosing in time by adjusting a 0-10v signal to an inverter to make sure that a flag makes a sensor in a set window. I have installed an encoder on the filling head and an mpl servo to the dosing. I have then used an MAPC instruction to follow the encoder, the cam is 0-360 and it follows a straight linear line. I have installed of this as a temporary set up on one of the filling machines (we have 2) and it is working perfectly. I have now installed this on the second machine as a permanent set up with a panelview plus 7, L71 cpu. However it is giving a very strange problem on first power up, the encoder is giving the exact same position as before it was powered down. however as soon as the MAPC executes the servo axis  faults, giving an overspeed fault. the servo doesnt even look like its attempting to move (however it is through a 10-1 gearbox). if i then home the encoder it then runs absolutely perfectly until it is powered down again. I am beginning to think it may be to do with the master lock and cam lock position, as the cycle stop position of the two machines are different. however I just cant seem to get my head around i the difference between them.   Hopefully that makes sense any help would be greatly appreciated Thanks Rhys   c1_dosing.ACD
  13. Hi, Is there any setup to manage alarms in one PLC from multiple CX-Supervisor runtimes running on different computers? If I get an alarm, it shows up on both runtimes. If I acknowledge from one runtime, I also want it to be gone from the list in the other runtimes.
  14. Hi All. i got a problem when accessing local reporting service website using microsoft web browser control at HMI. it showing only half of page. when i open the website from internet explorer at same server where i develope HMI, i got no issue. please your advice. thank you.

  17. I need to learn about position control for 2 axis with a QD75MH2 module. I know how the basics about programming with the Q Series PLC but I've never done any positioning control. I'm having a really hard time understanding the program I have to modify and I don't know where to start. Is there any course you might recommend? Even if I have to pay for it. Thanks.

  21. Hey guys, first post!  Friends at Practical Machinist sent me over here b/c we were stumped.   I have a Mitsubishi 500M control CNC machine.  There is a section of the ladders that i don't understand, and Mitsubishi couldn't help, and the OEM is defunct.  I do not have a hardcopy of the ladder circuits. I have an output , [Y13], that i can't get to turn on because of an internal relay | M453 |       see pic 1 When i searched for relay M453, it seems as if it's in some sort of array function.  see pic 2 None of the relays from M448 thru M512 ever turn on.  I understand that all these are controlled thru this circuit, but i have no clue what is going on with the R registers, and how the heck these internal relays can be turned on. Can you guys help explain?   Thanks!
  22. Sequencer Input

    I have a program using the SQO instruction. However, I am looking to control my program with a sequencer input. I have never used the sequencer input before and I have 16 sensors to move cylinders using the sqo.
  23. I forgot how to do this. If I put in let's say 1234569632<cr><lf> how do I store the carriage return line feed along with the number in my ST file??? 1234569632(chr$13)(chr$10) something like this, but can't remember. Thanks
  24. Good day, I´m helping with small project and currently i am stuck because of this problem. And I hope you can help me out. I´m using PowerFlex 525 connected with AB CompactLogix 1769-33ER PLC via EtherNet/IP. Connection is working, I can read and write values from/to 525. To configure both devices i´m using RSLogix 5000. 1) First problem occurs after I loaded configuration to 525 and it´s, that 525 keeps overwriting values of Accel and Decel Time 1. It happens when i directly change parameters in Module Properties (online) or after I upload configuration to device. It happens even if i set parameters directly to 525 with its HMI panel. - I kinda get around this problem when i use Accel/Decel Time 2 for Step logic, but if i send direct reference value motor still jump to it and that is not good, especially when changing direction of rotation. 2) Second problem is that I cant get Speed Sources and Start References right. Usually Is working only option 1 and others are not, or they are doing something else that they should. For better imagination this is what i want to do: I have 3-state switch (left = 1 ON(DigIn TrmBlk 02), 2 OFF; center = 1 OFF, 2 OFF; right = 1 OFF, 2 ON(DigIn TrmBlk 03)), In center position I want to control 525 with EtherNet (already working when: Start 1 AND Speed 1 = EtherNet/IP). In left position I want to control motor directly with Drive Pot and In left position a want to start Step Logic (which i have already set) - Funny thing, If I set Start 1 = Ethernet, Speed 1 = Step, Start 2,3 = DigIn, Speed 2,3 = Drive Pot then in all three position motor goes in Step logic.. Or when i get left and right position working then Ethernet is blocked.. and this kind of things.. I Attach print-screen of my current settings, if you need something more just, tell me. Thank you for your time, and I hope someone will be able to help me.
