  1. ello I have a powerflex 400 of 25HP for a 60amp 25HP motor, the motor have a belt that move the clarifier of milk. It is a process that requires strength to move.So I try with the motor without the clarifier the vdf works well with a constant amp of 12 to the max of 50hz that is set up with a ramp of 600 sec.Then I try with the belt that move the clarifier... The vdf start the ramp with a wird amp behavior like 10 sec 100 amp and then 13 amp for 10 sec.When it gets to 50hz (the max) it starts the same behavior 13 amp when it reach the max RPM and when it decrease a little bit it gets 100 amp to get to the max RPM again.In this vdf powerflex 400 I didn't see the % of torque options that the last one Fuji had.Someone told me that powerflex 400 is not for power processed, they are focus in pumps and blowers more alike, and that I need a vdf vectorial like a powerflex 725.What do you think...PD: as the 100 amp is like 10 sec the protections dont show up. PD: I made a try with water and hot water, in that point with the max hz  (and 6800rpm) when the hot water start to flow the amp gets constant in 75 amp, but the motor dosnt get to the 6800 rpm again it just keep trying in 6700rpm and it mantains the 75amp triggering the motor protection for overload.
  2. How long  could be INT array. For example can I build INT[365] or DINT[365]? When I use more than [32] my controller fails. Thanks. 
  3. Dear Experts In our plant, we have only one Allen Bradley PLC (Compact Logix L24ER) in one of our testing machines. We need to check online reason for error :LH Motor Negative overtravel Please let us know if it is possible to get communicating software RS Logix 5000 for trial Regards  
  4. Hi everyone, To explain the problem a little bit: I have 2 systems that are equal, they have 1 PLC, 1 Inverter and 1 Servo Axis (Image01). The devices are connected via EtherCat. The thing here is tht in these systems the PLC and Servo Axis is the same but the inverter is different. My goal is to have the same project on both systems and depending on the inverter detected use the correct program. What worked: If I add the 2 Inverters and 2 Servo Axis on the project on different nodes (Image02), I can detect which is present using the variable _EC_EntrySlavTb[n]. My issue is that if I want to make more replicas of the systems using different inverters I will eventually hit the Axis Number limit for the PLC while in reality I am only using on Servo Axis at a time. What I wanted: I would like to be able to control 1 Servo Axis with 2 different inverters (only one active per PLC) (Image03). What I tried: The axis parameters can be set using a variable of the type _sAXIS_PARAM, however it seems that the option to change the axis basic settings is not available (Manual: NJ/NX-series Motion Control Instructions Reference Manual (W508) page 5-58) (Image04). The axis basic settings is where the definition of the output device plus control words are set (Image05). Is there a work around to solve this issue? I would really like to avoid having to manually change the output device for the Servo Axis every time I make an update on all the systems.   Best Regards, BR  
  5. FX3U to FX3U via wifi

    Good day fellow PLC ninjas! I have a question/ concern which I would love your opinions on. We have 3 FX3U PLC’s+ENET cards. Two of the 3 PLC’s move around in an EMS trolley. The other is a ‘base station’ with a GOT2000 connected via Ethernet. Base PLC IP = 192.168.1.11 HMI IP = 192.168.1.31 Carrier 1 IP = 192.168.1.61 Carrier 2 IP = 192.168.1.62 I have programmed the base PLC to use Active communication; we are using fixed buffer communication to send and receive data to/ from the Carriers. The carriers are set up as Fullpassive ‘slaves’. This part works well and the update time changes (using a counter in the base station) from 1s to 100ms (because it enters a different work station).  My issue is the following: using a network sniffer (WireShark), I pick up plenty of re-transmits and sequence number errors coming from the base PLC’s ENET card. This is troublesome and causes delays when the update time is required to be fast (100ms). I am sending and receiving 10 words of data. The wifi seems stable, and there is minimal noise in the area. The power has been turned down and the antennas used are suited well for the application. The antennas are at a similar height to minimize possible loss of signal. I have LOS (line-of-sight) to the carriers at all times; to at least one of the antennas (I am using 802.11n). Has anyone picked up issues or found settings which can be used for comms over wifi? I can easily do this using a S7-1200 Siemens PLC and have done so using 12x S7-1200 clients and 2 AP’s with 1 base PLC. I have also successfully done this using 8xFX3U client with a System Q base PLC. My suspicion is that the delay in reading and writing to/ from the BFM in the ENET card is causing this. I am not sure that if I change to a FX5U will help. The communication cards on the Mitsubishi PLC’s seem very limited. Does anyone have any technical details on the access times between the CPU and communications cards’ BFM? Help is as always, appreciated.
  6. simple motion cam curve

    Good afternoon, I have a problem in an application for a rotary knife, I'm using a MR-JE-B servo to make this movement, while my material is powered by an inverter connected to a modbus rs485 network, with a 5v encoder connected directly in motion. I'm having some problems and I think it's my cam curve. I have a very high refeneration, and the system doesn't obey the size of the length I want the cut. It always cuts the same size, regardless of the configuration I use, it always cuts to 245mm. Put some photos, how are my settings. Grateful in advance, if anyone can help me.

  7. Dear Colleagues,   I require some help with regards to setting up virtual machines, We have some ControlLogix 1756 PLCs scattered around site running on different version (v20, v21 & v32). My company requires all software installations on company computers to go through IT. Installing all these versions on single PC is really a pain (going through IT)  for new hires and for new PCs. I am trying to suggest using virtual machines for each version that can be shared/distributed among the engineers and also to give engineers some autonomy in the VM environment.    How do I go about this especially with respect to licensing without violating the terms of use both the operating system and the automation software? 
  8. 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  
  9. CJ1M con CJ1W-EIP21 a ControlLogix

    Hello I am trying to communicate a CJ1M with a CJ1W-EIP21 Card, with a Logix Control, but I have not been successful, what I am looking for is to read data, from the OMRON and see it in the Logix Control, but I have not been able to establish communication, I am looking for someone You will already have a functional example, with the backups of both PLC'S, to be able to observe how they made the configuration. Thank you for your support Greetings
  10. I'm having trouble with some Powerflex 525 drives. Right now what I need to do is run them manually from the keypad to test conveyor belts.  Is there a way to do this and if so how?   Thanks in advance.
  11. 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. 
  12. 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
  13. Hello Everyone. We have Schneider TM241 PLC Along with Citect SCADA System at 100MWp Solar Power Plant to monitor and control various equipments like Inverters, Switch-Yard, MFMs, Weather Monitoring Systems etc... Government Authority here asked every solar plant to control the generation as per the instructions by Load Dispatch Center, for that we need to implement logic to control Generation as per requirement. For that we are controlling generation from inverters by giving them generation setpoints calculated by PLC using PID function.   But we are facing one problem while using PID. (FB_PID of Toolbox Library)   Suppose we need to generate only 60MW out of 100MW. So we set PID setpoint to 60MW and according to that we get PID output and according to that PID output value we provide generation setpoint to every inverters.   This system works very fine until the clouds comes into the picture.   Now suppose Setpoint of PID is 60MW and PV is also near about 60MW, and suddenly large cloud comes over plant and block solar radiation.   In this case generation comes down to 10MWp(or any value below 60MW), So output of PID will Increase and keep increasing and settle at the Maximum value. but without solar radiation generation value stays very down then Setpoint.   Now suddenly Cloud moves and again solar radiation increase, but the PID output is maximum at that time so, Suddenly Generation goes from 10MW to near about maximum capacity (100MW) instead of 60MW, and then it will slowly comes down to 60MW.   We need to rectify this generation shoot up when cloud moves. Anyone have idea how can we solve this problem or anyone have programmed PID in this kind of situation.   Is there any function block available to do this correctly like function block of PID with two Reference or something like that...   We are using TM241 which is CoDeSys based PLC.
  14. 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    
  15. So I'm having trouble writing a FBD within my current program for a slitting line. I need to keep a constant tension on my web as it is being recoiled onto our recoiler. I wrote a simple program using a sensor to read the growing rate of the coil to get a radius and I have feedback on my torque on the recoiler motor. The simplest math for this application without getting into anything too fancy should be Tension(lbs)= Torque(ftlbs)/coil radius. only problem is when its less than a foot then my calculation is thrown off and it actually shows tension goes up until it reaches the one foot mark then it seems to scale correctly. Do I need to scale something else? Any help on this would be appreciated.
  16. Hello All, First time working with PLC. Get the hang of it from stuff I researched. Having an issue with an axis setup for a servo motor.  When I try to do an auto tune it gives me an error that axis is not configured.  Source: Config Fault    Condition: MotorDeviceCode- INvalid attribute      ACtion: Immediate Stop Fault Entry: Type 8, code 9 subcode: 1314 stopaction: 4 Statechange: 3   I was wondering what am I doing wrong? Any leads or source information I can use to solve this. 
  17. Hi, got a mental block lol.  Got a machine we are modifying, currently got most of the code in place. Working on a fault routine now. This machine doesn't have an HMI or wide array of PL. Nothing major just a simple vision system check. Currently have 6 faults that will stop the cycle running. I'm wanting to have the beacon light (Red light) blink for the cause of the fault. For example: Scenario 1- Fault stop for bottle check NG:  (two) .5 sec blinks -  2 sec red light off -  (two) .5 sec blinks ..... repeat  Scenario 2- Fault stop for bottle check NG and reject sensor blocked:  (two) .5 sec blinks -2 sec red light off - (three) .5 sec blinks - 2 sec red light off....... repeat I have the code a few different ways but it looks "dirty". Any suggestions? Thanks in advance  
  18. Mitsubishi FX5-4LC

    Hello Guys,                      can anyone help me programming of FX5-4LC temperature control module with FX-5U80MT PLC. I want to Read present temperature value of each channel and want to set Temperature Set value from PLC.
  19. 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?

  21. Control Panel

    Is it possible to view the values / states of all inputs, outputs and workbits (e.g. 64.00 through 64.15 on Omron CQM1 PLC) on a single screen or control panel within CX-Programmer software?  I'm trying to troubleshoot some ladder logic that I wrote and need to know the values of 5 or 6 inputs/outputs/workbits simultaneously.  Having to scroll up and down through my ladder logic repeatedly does not work well with code that changes state every 5-10 seconds or so. Any help is welcome.
  22. 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
  23. Logic to control many motors

    Hi everyone, I trying to develop a logic to control 6 motors. Two motors needs to working and four motor will be in stand by. When one of the two motors fail, one of the four motors will start to work. Another rule is, when one of the motors that is working reach the preset time of working, the controller will stop that motor and start another motor with low working time, and so on. I'm have difficult to solve this problem. Can someone help me, please? Best, R.  
  24. 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?
  25. Control Panel Drawings

    Gentlemen and Ladies,                             This post might come off as generally lazy but this is purely in the interest of saving time. Our company has been building control panels for quite some time. I have been doing the design for about 10 years or so. We typically build Allen Bradley type control panels. Our main customers are water/wastewater so they are typically Compactlogix with basic IO. (AI, AO, DI, DO) modules. Recently i've been using the IO Wiring System modules. These save an incredible amount of time. However, they are quite big and require a decent amount of space. Our smallest control panel size is usually 36x36 and that is pretty tight. My question to all is, does anyone have a set of control panel drawings for an Allen Bradley compact logix system without these wiring modules? I am looking to create a smaller control panel, and I just haven't had much time lately to sit down and do the design. This is indeed a shortcut, but time has been limited on my end as of late. I apologize if this is out of line.   Thank you,
