  1. 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. 

  2. QD75M4 AND MR-J2S-40B

    Hello i have problem about connection between QD75M4 AND MR-J2S-40B  now MR-j2S is display "Ab" every time i can't solve this problem 
  3. I am looking for how others have set up vertical axis motions using the Kinetix 5700 servo system. I have a 2 axis pick/place unit with a horizontal axis (X @ 2500mm) and vertical axis (Z @ 1200mm) that works as designed during normal operation. X axis has no holding brake and Z axis has a factory installed 24vdc to unlock brake. There is a GuardLogix L81ES control system that handles the safety and control. On pressing E-stop/opening Gates the vertical axis will stop the motion, apply the brake and hold with no problems. (2198-D032-ERS3 Drive, 2198-P031 Bus Power, MPL-B430P-MJ72AA X Axis, MPL-B330P-MJ74AA Z axis) The issue that I ran into was an accidental download of the program without activating the e-stop and the vertical axis dropped unexpectedly when entering program mode on the processor. I am aware that this instance was my fault as the programmer, however I am also concerned that this might occur again in the future if the controller ever enters fault mode or someone else completes a download. I have done some investigation with the "ProgrammedStopMode" parameter on this single motion axis and attempted all 5 options and the vertical axis still has a free fall drop for a second before the brake grabs hold - so evidently this is not working for me. (Page 24 of Vertical Load/Holding Brake manual - https://literature.rockwellautomatio...t003_-en-p.pdf) I am curious if there needs to be something done elsewhere as the X and Z axis are set up as coordinated axis? I also am unaware if I need to preform some action/parameter with the bus power supply for this? The current state of the machine as it sits now is preforming a MSF in manual mode after 5 seconds of inactivity or 30 seconds in auto mode. This axis is usually in demand every ~22 seconds. This will shut down the axis after preforming a brake test on the vertical load and seems to function OK, however it is still in the back of my mind the issues mentioned previously if we ever enter a controller fault while indexing. Thanks for your insight
  4. I searched FX5 manuals and it appears that with the high speed inputs I can run a stepper motor without a motor controller. I have little experience setting up a new system with any motor but have made changes with servo issues. I sent a request for info from my supplier but I still have some questions/requests.   1. Can an FX5U control stepper motors without a motor controller? 2. If not then what Q/R series setup is required 3. Are there any document to help understand? (program examples are welcome)   Main objective is to run a sensor head to 3 or 4 specific points using a belt driven linear actuator with a nema motor.
  5. 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    
  6. Hello to everyone! Our company is trying to make a quick disconnect for motors that connect tp servo amplifier R88ND-1S. As I know Omron doesn't have any options to do it or make an extension cable. Does anyone tried to cut the cable and make custom connector? If yes, could you share your experience? I'm afraid of having issue with encoder count. Thank you in advance! Scotty.
  7. We have been working with PLCs for long time. We used to develop PLC logic, partly test it on an emulator and test the rest on the partly energised equipment. From time to time working with computer software development (C# and JavaScript) I was always looking for something similar to unit testing in the PLC world. As I couldn't find anything at that time I've started developing own automated testing tool. Now we use this tool, which basically simulates PLC inputs in defined actions and checks expected behaviour of internal tags or/and PLC outputs. If it behaved the way we expected, it's PASS, otherwise it's FAIL. We break complex logic into small parts and create unit tests for it. By creating more of these unit tests we can test PLC logic of any complexity. The software called PLC Logic Prover and it's free at https://www.controlx.io Recently, I've been told that there is no point to develop anything new if there are already great tools on the market. Honestly, I didn't do proper research earlier, so I'm here asking the experts. What do you use to test PLC logic? What automated testing tools do you use? Is it using IO simulation or it can test logic by other means? Your replies are appreciated. Thanks, Alex

  8. PLC Panasonic FP0R Motion Control

    Syafiq Aiman posted a topic in Other PLCs

    Hi, I am using FP0R C32T, i use FPWIN GR to make plc program using jog operation instructions F172. I used the program exactly like manual, but still got error code 45? Did anyone know about this thing?
  9. Hi, Can anyone advise on how to upgrade the firmware on Kinetix 3 drives (2071-AP8 Series A)? There is a firmware update option in Ultraware, but when I try that it says something like f/w version does not support upgrade. Is it actually possible to upgrade them at all? You can download new versions from the AB website, which suggests it must be possible. They currently have v2.00, and latest version is v2.23. I know these are old drives, but they still work so might as well get some use out of them. Thanks, James.

  10. System forgets servo position

    Gman1 posted a topic in Mitsubishi

    Hi all! We have a problem with a Mitsubishi system. After switch off the machine in home position and back on, it resets the servo encoder value to 0.  I checked the servo parameters, and the Absolute encoder is enabled, the ext. battery is ok and no zero reseting in the program ( I think...). Is there a parameter I should check or some setting in the intelligent module? The system consists Q01CPU, QD77MS2 im., J4 200B amp with 6v battery, and HG-SR152 motor.
  11. I am trying to use an Automation Direct Productivity P2000 to control a Kinetix 300 servo drive using Ethernet/IP.  I got the EIP working fine using Explicit Messaging.  The hardware enable and overtravel limits are hardwired ON.  The drive doesn't show any faults.  When I turn on the software ENABLE bit (bit 7 of byte 0 in the Output Assembly), the Ethernet communication stops.  Motionview continues to work, but if I disconnect and reconnect, it can't find the drive.  I have to physically power down the drive to reestablish Ethernet communication.  Once I power back up, EIP communication resumes with no issues. Any thoughts?  What am I missing?
  12. Good Afternoon  im a complete newbie when it comes to PLCs but have done plenty of PIC programming in the past. I've been gifted a couple of FX0s 20mr units to try to repair something I made with PICs years ago. It got damaged during a move and I can’t see well enough now to make PCBs anymore so thought that this might be a solution. The basic operation is  1. switched on 2. motor A moves till hits limit switch (X000) 3. Wait 2 seconds 4. motor reverses till hits second limit switch (X001) then once this has been completed then the following  5. Motor B turns clockwise for 30 seconds then stops  And while Motor B is turning I need Motor C to turn until hitting limit switch (X002) I then need to get it to repeat on the press of a button but I need to reverse operation of Motors B and C I am using double position relays to drive the motors so motor A is on Y000 and Y001 if I power either relay the the motor turns in that direction. Same with Motor B and C Y002 to Y005 is this something that’s possible with one of these controllers or am i going to be programming a PIC to control the PLC ?   All the various COM and powers are connected up, I can individually make every motor do what I want, but the program doesn't flow from one item to the next. but this is probably just me      
  13. Hi, I'm fairly new to motion applications and I have an interesting (to me) problem to solve. I'm using Kinetix 5700 with MPL motors to drive a pick&place carousel and a conveyor belt. I have a virtual master that driver the carousel in 1:10 ratio. The virtual master also drives the conveyor belt, the ratio is given by the carousel diameter and the conveyor driving cylinder diameter +  2x the belt thickness. And I'm using MAJ to drive the master and the MAG instruction to drive the carousel and the conveyor. This all works well. BUT: the carousel does not pick the product in the same place every time. That creates irregular gaps, or pitch, between the product on the conveyor which causes some issues down the line. Is there a way how to superimpose a value to the conveyor axis to ensure the pitch is regular at all times. Something like the ADDAX instruction it Trio motion controller for example? I'd want to have a sensor that detects the edge of the product and compares he encoder value to an expected value and slows downs or speeds up the conveyor accordingly. Thanks a milion.
  14. 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  
  15. Dear all, I had bought a mitsubishi plc fx3s-20MT/ESS which is the source output and I plan to try to send pulse to Mrj3a Servo Drive. According to the manual, it stated that the servo drive able to support the source type plc but I do find out that manual also mention that only sink type plc is suitable for melsec servo drive.  Anyone can help me in this case? 
  16. 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!
  17. I have a Mitsubishi FX5U-32M with 3 MR-JE-40C servos. Our system will be used in a robot cell, and needs to convey some information to the customers system, which is this EtherCAT side of things. They want to know RPM, torque values, position ,etc, of things on our system.. Our Mitsubishi supplier recommended an AnyBus X-Gateway (AB7961). They have a few YouTube videos on configurations, but unfortunately none on the Mitsubishi side i found. I've only been using Mitsubishi for a little over a year, but know my way around GX Works 3 pretty well.  I come from the Rockwell world with EDS Files and tag based setups, and for the life of me cant figure out where to start with this AnyBus. I've gone to the support page, got all the downloads and software, and gotten online with the Anybus. As far as beginning to setup the Anybus in GX Works side, to setup what registers i want to send, im lost... Anyone out there have experience with this sort of thing?
  18. Hello there, I am using a Kinetix 5700 drives to control bunch of axis. HW used : 5069-L320ERMS2 GurdsLogix, 2198-S086-ERS4 Servo Drive with MPM-B2152M-M motor and the 843ES-SIP12BA6 safety encoder. All is working fine except I can't figure out how to dynamically change an axis velocity  controlled by a MAG instruction. I have a virtual master axis controlling the velocity and each physical axis is controlled by a MAG instruction with a gear ratio. In my safety program I have SFX and SLS function block used to determine the safe speed limit. The  SLSLimit output of the SLS function block is linked to a SS1 Request of my servo drive. This causes the axis to stop when safe speed limit acceded.  What I'd like to be able to do is to dynamically change velocity (limit it to safe speed if SLS instruction is active) of each axis without having to change the gearing ratios and thus avoid the SS1 safe stop action.  I know how to do that using JOG or MOVE but is it even possible to do that using the MAG instruction? Regards Martin
  19. Is there a way to monitor the Temperature of a Servo Motor on Allen Bradley Servo motors... MPL? PLC: CompactLogix 1769-L30ERM Drive: Kinetix 6500   Motors: MPL-B310P-MJ72AA, and  MPL-B560F-MJ72AA I would like to be able to monitor the temperature, and flash a warning screen on the HMI if the Motor gets too hot, or perhaps shut down the operation before the Motor overload trips. The drive and PLC are connected through Ethernet IP What I don’t know is if that Motor heatsink temperature information is available to the PLC.
  20. Hello, Have this error come up constantly and can't be reset. Motor hasn't tried to drive at all. Second motor showing same problem. This is a new configuration on new machine. Other inverters configured without any problems. Anyone seen this before or any ideas what could be the issue.
  21. 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? 
  22. This is a bizarre one... CompactLogix, 1769-IF8 with 1492-AIFM8-F-5 wiring system. My client has reported several instances where one of his flow rate displays is frozen at its maximum value.  Each time, I have gone to the site, found that the value in the analog input tag is at full scale, and measured more than 20mA at the input - as much as 28mA!  I measure it using a clamp-on meter and I measure it at the input module (1769-IF8) and the external, pre-wired terminal block (1492-AIFM8-F-5).  I cycle power to the PLC.  No change.  I cycle power on the transmitting device.  No change.  I disconnect and reconnect the input (signal wire at the module or the terminal block) and everything goes back to normal.  This has happened on multiple channels on multiple input modules and with two different types of transmitters. I didn't install this system, but it seems to have been done properly and it had been running fine for many years.  These problems just started happening out of the blue. Has anyone out there had any similar experience?  This is a new one for me after more than 25 years in the business.
  23. Hello, I am trying to receive data from a scale via rs232. my setup; compact logix l18er with a 1734-rs232ascii point IO module to receive the data. I am receiving data from the scale, but I have very little understanding of ascii, so I do not know how to convert the data I am receiving to something use-able. any help on how to convert the data to something I can use or where to even start would be much appreciated. using a scientech ZSA 210 scale https://scientech-inc.com/media/downloadable/files/links/1/2/12222-d_rev-f_instruction_manual.pdf
  24. Hello guys, I am running an application for packaging measurement using a sick DFS60B incremental encoder (programmable from 1 to 10000 PPR). In more detail, it passes packaging on a conveyor belt and we have created an inspection station and an expulsion station (defective packaging), so we use the encoder to check at specific points of the packaging for defects (we use special sensors to check defects). ) (there are four in total). However, the problem we are having is the following: When reading the encoder in the PLC, the same means that performs "jumps" and does not enter the windows (GRT and LES) created on the ladder, ie, as if it were not continuous. . I understand that because the VHSC24 card works at 1 MHz in counter mode, this type of problem should not occur according to our application is not even 100 KHz. For example, our case: Using 1000 PPR and the motor speed (coupling output) is 3600 RPM (in practice it is around 1750 RPM) the frequency is calculated as follows: F = (PPR X RPM) / 60. : F = (1000x3600) / 60 = 60 KHz, ie 60 KHz is much less than 1 MHz, I think this kind of problem does not occur. Application Info: . Studio 5000 V31 . PLC Model: Rockwell 1769 - L19ER-BB1B CompactLogix 5370 . Encoder Card: 1734-VHSC24 / C . Incremental Encoder: Sick, DFS60 up to 10,000 PPR and HTL Electrical Interface. Using a 200 mm circumference / perimeter wheel. . Motor Nameplate Data: 1670 RPM, 0.37 kW / 0.5 HP, 60 Hz . Inverter: Weg CFW500, Output Frequency 62 Hz. Card Settings we use RPI: 2 ms Type: Counter, but we already use it as Encoder X1 Store Count Mode: Disabled Filter: No Filter, but we use 50 KHz and 5 Khz filters in our tests. Counter Attenuator: 1 Wiring Diagram VHSC24 We turn on encoder A at input 0 and encoder Aret at input 1 In logic (Structured Text) Using the PMUL instruction to convert encoder (Pulse) data to mm scale. (Ladder) The window comparisons part (GRT and Les) and other part of the process. We emphasize that we performed the tests also only with the reading and comparison part of the data, excluding the other parts, precisely to verify the issue of Scan, but the problem persisted. If anyone here in the forum has some information that can help us, I would appreciate it.
