  1. NX1P2 Motion Control

    Hi:       I need to change an old PLC  with NX1p2  to control 3 servo motor by means of Analog Outputs couple with encoders, My job is to change the PLC only. So the servo drives and drivers are untouchable (No budget and involve too much mechanical works).   I observed that Sysmac Sttudio Axes setting has this: Servo Axes, Encoder axes, Virtual Servo Axis and Virtual Encoder Axes.   I believe the Encoder Axes couple with Analog Output is able to to do the Job? If so, what function block should i use? If no, do any body have a suggestion of any function block i can use? Thanks  
  2. So I'm new to the automation scene and in my training I decided to setup a little test rig, plc, drive, servo, sensor, hmi...etc.  Everything is wired and hooked up. What I'm trying to do is simply get the servo to spin. here is a screenshot showing what I have. I think there are some flags on the servo itself that need to be set but I'm not sure how to do that. In Base(x) I have tried 0, 1, 4, 5, 35. Any help would be appreciated.
  3. Hi everyone, I have an annoying fault on my Kinetix 5700 drive: M01-Safety Feedback. I know this fault is generated by  the SFX instruction in my Safety program that sets tag: "Axis.SFXFault" to 1. The problem is that the instruction is NOT in Fault (Fault code 1 = no fault). This error occurred after Safety encoder 843ES lost it's IP address. I used Bootp to set it gain. And reset the SFX instruction. I can see the encoder in studio 5000 rev 32.12 running and ok.  Does anyone encountered this problem? How can I clear the fault?   Thanks
  4. Create TCP/UDP Socket

    I'm trying to send an int over TCP using a MSG Socket,  Compactlogix ==> Arduino Ethernet Shield I have set up TCP communication between two Arduino Uno's using Ethernet shield. I've set up the one as a server, the other as a client. server IP: 192.168.1.21 port 23. If the client is connected it reads incoming data as a byte or an array of bytes. The data between the two has been verified to work. I'm now trying to transition the communications between a compact logix-L32E. I'm looking to send a byte (or int being as there's no byte data type) from the Compactlogix to the Arduino using TCP. To my understanding I need to use a socket create, open, read/write, close. The manual to do this is vague as a step by step procedure. Does anyone have an example code for socket programming? I can open rs500, rs5000, and studio 5000 programs. If I can open a file to use as a reference I can translate it on my own. Any help/advice would be greatly appreciated. 
  5. This is hard work! I've installed the CODESYS OPC Server V3 in the hope of using it to communicate with my Schneider PacDrive LMC. Apparently the PLC doesn't support OPC tag browsing so I need to export the symbols from the SoMachine Motion project file in a format that the OPC server can use. I've got the Symbol Configuration panel open and can see the symbol tree. What do I do next?
  6. MDS instruction would not complete

    Hany any you of guys dealt with MDS instruction not completing and being stuck on .EN bit but the motor itself just stopped running out of nowhere? I did read the tech note on this on Rockwell's website. Am mostly wondering if any of you have dealt with this and what you did to fix this.
  7. I have a purchased Machine that came with a Siemens LOGO 8.FSR PLC (Smart Relay). Generally we use Allen Bradley or Mitsubishi. Anyway, we need to communicate data between the LOGO and an Allen Bradley Compact Logix.  I do not desire to add an additional network to the AB but as best i can tell the LOGO is exclusively Modbus TCP/IP. Has anyone come across a similar situation?  I look online and did find an  Anybus module that claims to be able to link them together.  Looking for anyone who has faced this challenge and succeeded, or failed.   Thanks
  8. Hello everyone, I have a Kinetix 6000 CIP drive (unwind) and I need to control its speed by a PID controller. I have everything working except the MCD instruction doesn't pick up on the PID output value change. It changes the JOG speed, which I use to control the unwind, if I set the speed manually, which is slow. The PID changes the speed almost continuously. Any suggestions are welcome. This is how I'm attempting to control the speed: A1_r_JogSpeed = PID output value   Thank you    
  9. Hi all, I am studying how to control servo with PLC Mitsubishi Q-series. When I click Servo_parameter in Simple motion module setting tool, this annoucement appears.  Does anyone know why it appears? I tried reinstalling MR-configurator 2 but it didn't help. Please give me some advices. Thank you all!
  10. Hi Every one, I have two 2198-P070 bus power supplies for that I’m using for four Kinetix drives, 2 drives per power supply, all controlled by one processor (5069-L350ERMS2). I have an enable contactor setup for each power supply for each set of drives. I have them configured as DC bus groups 1 and 2 respectively. I had the first set of drives working, setup inside the motion group, with no issues. When I added the second power supply and drives. I found that when I added them to the motion group I couldn’t get the enable contactor to close for the first set of drives. I f I took them out of the motion group and made them ungrouped then the first contactor would close but then I couldn’t get the contactor on the second set to close. Do you have any thoughts as to what I might be missing to get these to work? See the screen shots for more detail. Let me know what you think.  Also, I have heard that only one motion group is allowed per PLC, but my question is : Can I use  sevral axes and Power units in the same motion group? 
  11. I am desperately trying to understand the OMRON way of programming (28 yr. AB programmer) when it comes to Motion Control.  I am pouring over example programs and what I can understand in Omron manuals.....  What I cannot find is where you get all the bit level information from for individual axis....  For example, just a simple bit signaling a Servo Fault; I have a program that I have been studying and there is a bit with the variable MC_NailPunch_Station.MFaultLvl.Active, it obviously comes from the Axis "MC_NailPunch_Station", but I cannot find the reset of that variable anywhere in the program, in any setup....nothing. Is there a list somewhere of things like this I can use in my program for status bits etc.?   Thanks,
  12. Control Logix 5561

    Hello  We have just purchased some equipment with a Control Logix 5561 (1756-L61/B Rev 13.40). The compact flash card is missing from the unit but the seller says the unit was running in his facility prior to shipping. Does the 5561 have internal memory where a program is stored? Is the Compact Flash used only for recipes and persistent data? Thank you
  13. I'm wanting to get upload the program from a CompactLogix L31 Controller.  I'm using a generic (non Allen Bradley) "C2G brand" usb -->rs232 cable coming directly off of my laptop because I don't have a serial port out.  The rs232 side of the C2G cable is a "pin out" or male end, and as you can see in the picture, the serial port at Channel 1 on the controller is also male.  I'm using a generic (non-Allen Bradley) null modem (female-->female) cable to complete the connection.  Ultimately, I'm not seeing the controller on linx.  But that's a result of me not being able to configure the driver.  When I try to auto configure this driver, Linx gives me an error saying, "Unable to verify settings due to a NAK!" btw, the rs232 cable going into channel 0 is for the HMI on the machine. A pv600 1. How do I get online and upload the program from the controller? 2. What does NAK mean?
  14. Hi all. I have a Kinetix 350 and an AB TLY servo motor. I'm using the drive's STO function. AC power is supplied into the drive, passing through an "M1" contactor. It makes sense to m e to keep that contactor open, preventing AC power to the drive, until the drive is fully awake.  Is that what you guys do? Someone suggested to me in another forum ( http://www.plctalk.net/qanda/showthread.php?t=121021&highlight=drive+awake ) that there is no reason not to supply power to the drive right away because the STO function is inhibiting power to the motor anyway. 
  15. Bonjour, Hello, I use a l33erm automaton and a Kinetix servo motor . This servo motor drives an engine with a chain moving in steps of 100 millimetres (there are 15 steps on the chain ) At each top of a cell this motor advances by 100 millimetre. in reality it advances from about 0 to about 100. Sometimes it is 100,002 times to 99,997 (this is important further) and when I give it a top it goes back to about 100 (100,003 times to 99,996) And so on and so forth up to no problem, I use a MAM with an absolute type of movement. It works.     However, this does not work any more after a rearmament following an emergency shutdown. if it is a 100,002 no problem at the next top the chain advances one step But when the engine is shut down at 99,997 and I give it the order to go to 100 it advances only by 0,003.  This only happens after an emergency stop (or door opening). Thank you for the help you can give me excuse my English this is a machine translation Un séjour sans faille
  16. Hello,, I have motion controller A series A172SHCPUN,, I have written the program ladder into the CPU, but I can't write the motion program.. i dont have the program to open file the program motion and I want to ask if I have the software SW3RNC-GSVE, my os computer is window XP, Can it be installed? and is the cable transfer used the same as the ladder transfer program cable (SC09)?
  17. Hello! I have a project where I need to use Allen Bradley PLC, it might be one of CompactLogic series. In scope of the project I need to transfer few real values to DirectLogic PLC that installed on customer side. DirectLogic PLC has installed ethernet card that support Modbus TCP, TCP/IP and UDP/IP protocols as it says on automationdirect website. I start looking for Allen Bradley PLC that support Modbus TCP or TCP/UDP protocol and did find clear information. Could you help me to find out a way how I can pass the data to directlogic PLC from CompactLogic?   Thank you in advance!   Regards, Scotty

    How could I find ON State duration of an Input/Output, in Compact Logix PLC? So it would help me to show in HMI that how long the I/O is ON.Kindly assist me.Thanks in advance
  19. Hello, I have an interesting problem that no one in our company can really answer for me.  We are using Drive Logix with a powerflex 700S phase 2 drive and controlling a machine that rotates 360 degrees, sits for a moment, then return back to zero degrees.  We are using the MAM instruction to tell the drive to run the motor to its desired degree.  The problem we seem to face, is when they change jobs, the weight changes and we have to adjust speeds in order to get the machine to rotate back up to 360 degrees.  Otherwise, the motor stops short.  It usually never faults or alarms, it just stops short.  For example, they might run it and it will stop at 240 degrees or 315 degrees rather than the 360.  My question is, why doesn't the drive continue to push the motor to 360 degrees?  Why wouldn't the drive fault out on something like over current?  It seems that it just stalls and stops.  Sometimes, the machine will be running great, but on occasion (1 or 2 times a shift), the machine will stop short again.  I am curious what causes this and how I might be able to fix this to force the drive to continue to try and get to that desired degree. Thank you for any help or input!

  22. From PM this morning

    Fairly new programmer doing first analog section in project at new job. Im using NCF motion with parameter for torque control to send the torque values  a+8 (leftmost word) and a+9 (right most word) to CX programmer. From there is where I get confused will I just simply be moving both cio 108 and 109 to to a D register?? or will I have to combine the a+8 and a+9 to make a Dword??? and then taking that value to HMI broken line graph. sorry again for creeping in your inbox but ive been looking online for 6 hours. would greatly appreciate any help
  23. Hello, I am not very experienced with Siemens PLC's I want to change program in one S7-200 CPU 226 (profibus). I have never connected my laptop to it before and I don't have that PLC's program. I have PC Adapter USB A2 cable for that and V4.0 STEP 7 MicroWIN SP7 program. I connected the cable, opened the program and tried different settings for connection, most of times the test in diagnostics says that status is OK. But! in communications window when ever I try to refresh the adapter is gives me error: "Class not registered" So I'm not able to upload the program from PLC to my laptop. Can anyone give me support?
  24. Hi, I am trying to do a merge move on 1S Servo. The condition are as follows: Task: Move 2 in(absolute value) and then Move back to 1 in (absolute value). I have to do this move 10 times in a row.  The application is material leveling after dumping in the mold. The only question i have is if I use just MC_MoveAbsolute command, the only buffer mode for transition available is velocity. Is there a way i can do it with position. I dont want to stop when I can go from 1 to 2 and 2 to 1 again and again. Its time consuming. But rather a nice oscillation motion without stopping to mimic leveling. Can anybody please help me out with this problem.   Thanks
