  1. 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
  2. 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.
  3. 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    
  4. Hi,I am connecting several computers and NS12 HMIs with a CJ2 PLC using EtherNet/IP protocol. And I would like to know the FINS Address (Net.Node.Unit) of the HMI and the computers. I suppose I need to fix their addresses using an IP Address Table. Right?? Anyway, I only know to do that with UDP, but I don't know how to do that under Ethernet/IP.Thank you.

  6. 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.
  7. 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?
  8. 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. 
  9. 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

  11. Hi all, after my complaing about my lack of network access in the workshop ive been tasked with fixing this so ive have some general questions about networking and concerning Ewons so this network will be used for connecting ewons to test products as well as general computer access the plan is to have 7 computer access points as well as 2 points to connect to product lines for testing my intial thoughts were to run 2 cables from our network to 2 routers, 4 computer access points and one line testing connection on 1 and 3 computer access points and one line testing connection on the other so first question is what type of ethernet cable should i use? i assume cat5 is fine, is it worth going for cat6 or is it just a waste of money? and should i be running crossover cable or straight through? do i need any specific routers or will anything do? will i be able to add splitters later down the line and be fine? or should i future proof a bit with more robust routers? my years of avoiding networking at uni has come back to haunt me i know the basics but thats all really thanks to anyone who can offer some usefull information i mention the Ewon units because ive been told that they need to be the only one on their connection to the network, although i dont know how true this is

  13. Hello, Can anyone tell me what types of Ethernet/IP device the  QJ71EIP71 can be configured as? Explicit message server, explicit message client, I/O adapter and/or I/O scanner? I'm having trouble finding this information in the manual: https://eu3a.mitsubishielectric.com/fa/en/dl/12484/SH(NA)-081157ENG-B.pdf
  14. Hi all,  I am trying to configure an Fx3ge-24M PLC using GX-works 2. I can successfully connect to the PLC using the USB cable, however i am having trouble getting a connection via ethernet. I have attached a photo that contains the only ethernet configuration that i can find, what am i missing here? I'm new to GX works & mitsubishi PLCs.  
  15. We have an application using a Mitsubishi L02CPU-P with a built in ethernet module. At one time the TCP/IP interface became irresponsive and a hard reset was required. The device is configured for binary communication and works fine using a GOT therminal and also operates fine when queried from a GX Works application. During debugging of a custom MELSEC application the TCP/IP interface stopped responding and could no longer be located using GX Works and the GOT terminal also lost contact. The L02CPU-P continued running the control application, but could no longer be contacted. The only way to recover was using the L02CPU-P reset button. I have heard developers being restrictive using the TCP/IP interface remotely over VPN and unstable connection due to the risk of hanging the device and not being able to recover without a personal visit to the device. Any experience from L02CPU-P devices requiring hard reset to come "online" again? Or does it enter some default state due to some internal exception handling?
  16. 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? 
  17. Hi to everybody. I'm beginner on Beckhoff so I'm having issues with connecting Beckhoff CX8090 and Weintek EMT3070a. I'm trying to use Beckhoff TwinCAT PLC Free Tag names to get data from CX8090.  I have followed instructions in EasyBuilderPro which are pretty straightforward. On side of HMI I need to select proper settings which should be: IP: 192.168.1.2, Port no.: 48898, ADS port: 801, AMS NetID: 192.168.1.2.1.1 I have succesfully imported all variables from my PLC program into the EasyBuilderPro. For testing I tried to create HMI just to see status of few inputs. I have no issues uploading program to HMI, but after startup I get message Device no response and communication is not working. On side of Beckhoff I have settings like this: AMS NetID: 192.168.1.2.1.1 Ethernet port X001: DHCP Ethernet port X101/102: IP: 192.168.1.2   I can access to CX using input ports X101/102 and also access to HMI through same connection. I have also tried to log on to windows CE on CX and tried to ping HMI and that also went ok. Also I have tried to add static route on TwinCAT to HMI with settings AMS NetID:192.168.1.3, IP:192.168.1.3 but again no connection. So physical connections are CX8090 X101 - > HMI, CX8090 X102 -> PC. From PC I can access both devices. I'm using TwinCAT 2. Can you tell me what I'm doing wrong?   Thank you
  18. My project is to read an RFID tag (ascii) with a Micrologix 1400, send the string to a PC using Ethernet/IP, lookup and compare in an Excel spreadsheet, and send back data (probably an integer) for the plc to use to control direction. I have to scan and compare an RFID tag to a list of 1400 possible part numbers, at different locations (more than 1 plc). I want the several PLCs to go to a single PC to make it easy to update when changes occur (on a weekly basis). Has anyone done anything like this? I'm assuming there will have to be some kind of vb or c+ application involved.   Thanks,  CK
  19. Hi everyone. I have project to use PLC Mitsubishi Q03UDECPU with QJ71EIP71 to connect with SICK FLEXI soft Ethernet/IP (FX0-GENT00030). I have check both manual but when I turn on Y0 (communication start) there are error code F100h on my QJ71EIP71 and I check that it can only use with produce/consume tag from PLC (such as OMRON, Allen Bradley) but for SICK device it can use only for assembly instance. Then I have use Ethernet/IP scanner (Molex) to read attribute (service code 72h) then I can read status from SICK but as I told before QJ71EIP71 can only communicate with tag-based. Then I have to ask everyone that 1. Are there method that can use QJ71EIP71 to communicate by use Assembly Instance? 2. Could I set consume tag name on FLEXI soft Designer? 3. Are there any protocol gateway device that match with these solutions?
  20. Hello! I have a problem with Allen-Bradley High Speed Counter card 1734-VHSC24/C. I need to make changes to the configuration parameter .OnValue1 (DINT) during the system is running. Now, for changing the parameter value, I need to switch off the module and this can not be done during the line is running. I think that maybe this can be done using the explicit messaging. I could not find information for this from internet, so now I ask you to help me with this item. If anyone have experience or knowledge of this, please help me. I do no have experience using explicit messaging. My configuration: Studio 5000 Logix Designer V24.00, 1756-L71S V24.11, Ethernet/IP, 1734AENTR, 1734-VHSC24/C countermodule.

  24. Control Panel

    cjcygan posted a topic in CX-Programmer

    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.
  25. 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
