  1. Constant Web Tension Control

    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.
  2. Hey all - I am working on a car wash system design that will utilize the Nayax payment system. Has anyone utilized them? How do I incorporate the device with PLC to automate the system. After payment is approved how can I send out that signal from them, all via ethernet on a managed switch w/ wifi for exterior comms for the Nayax.
  3. Hi All, Hope you all doing well in this pandemic life.  I would need your expertise with an issue I have been struggling with for past few days and thought to reach out here. I am working on a migration project with GE PLC and Citect SCADA 7.10. The GE PLC is migrated to ControlLogix L74 Rev24.10 while Citect SCADA is retained. For testing I only have L71 and L82 and could not managed to organise L74. When the code the loaded in L71 and connected to Citect, I cannot see tags in Graphic page but I see the subscription.txt in Debug folder shows all tags good . The same code when loaded in L82, the Citect works instantly.  Does anyone know this behaviour of PLC and SCADA? Regards, DeeEngr    
  4. Sorry for my bad english speaking. I want to change the baud rate to 19200,38400,.... for send it via Programmer-Serial-Port. The software GX-Developer can do it!. When the PLC is switched on, we generate a value in the data register D8116 and D8117. GX Developer reads the PLC type and data registers D8116 and D8117 at startup and generates a value. This value is written in D8118 and D8119. The big question is: how is D8118 and D8119 generated ??
  5. Can someone please suggest a Control Panel Builder that is located in Germany?   I work for a company in Australia and due to Covid 19, we are struggling to meet an onsite date for a project in Germany.   This project uses Siemens PLC gear, Danfoss drives, and mostly Schneider electrical gear. The enclosures are custom and stainless steal.    I have electrical schematics and enclosure drawings for quoting.

  11. Hello. I am working on a pilot project building an automated RV park. Our goal is to have people sign in online, or in person at a kiosk. Make their reservation, payment, and get their confirmation e-mail. In that e-mail, will be a QR, or Bar Code, that when scanned at the gate opens the gate, and starts a light that flashes at the site they rented. Power will then be turned on at that site, and a timer in the process will begin, based off their rental time. Once their time has expired, the power at the site will be turned off, controlled by a PLC, and relays.  So I am looking for help in all directions. I have some leads on some plug-ins for Wordpress that offer reservations, and other plug-ins that do Bar code production. As far as the web part I have that covered. We can generate a custom barcode, or QR code based on individual rentals and those can be sent to customers. So what I need is someone to help point me in the right direction of equipment that can speak between the online Barcode process and the PLC to allow a process to begin when scanned. Based off their rental parameters their power is turned on or off. Perhaps a SQL query in some form? I haven't used it, but am aware of its capabilities, and this does seem like an application where it would be used. Is there anything that you have used that are tried and true? I know it's a strange request, just hoping someone bites. Thanks in advance for any ideas, I look forward to solving this puzzle, one piece at a time. 
  12. Fatek PLC Communication Problem

  13. Hi all, I've ran into an unusual situation where I could use some suggestions.  I have an AB PLC working in the field, and an existing fixture that needs to be transferred from an Omron PLC into our AB.  I have an integrator who did some offline development with a welder that uses Anybus communication.  He sent a .ACD file to implement the logic from.  The file has an Ethernet module configured but more importantly, it's showing EDS not registered.  I've asked for the EDS he used, and none of them work when trying to register it via right-click and register.  I can export the module, but it won't import into the current PLC program because there's no EDS (shows EDS error after the import).  If I try to take the program that was sent to me online with the PLC, it will automatically upload and overwrite the build.  I can't even open the properties of the module to see what the integrator did. The end goal is to have the offline developed module implemented into the current program, but it seems like everything I've tried to do has me against a wall.  Is there a way to go online without uploading?  Maybe there's a way to implement this I haven't learned yet?  Any suggestions would be much appreciated, and if more information is needed, I'll be glad to provide it. More info:    PLC Type: 1756-L82E ControlLogix 5580    Rev: 30.014    Studio 5000 Version 30.01.00 - Standard Thanks, K

  20. 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?

  24. Connect PLC to Kepserver

    I have Delta 12SA2 PLC it has RS232 port and I have connected it to kepserver (by Modbus serial) and then factory IO Now my problem is that when I connect my PLC to kepserver the RS232 port becomes busy with the kepserver and not available in the ISPSoft and therefore I could not demonstrate factory io and my logic in run mode in the isp soft together like you do in your videos. My PLC don't have ethernet port but is there an option in kepserver or any way by which i can use the same serial port of the PLC in isp soft run mode and kepserver+factory io together so that I can simultaneously show the logic running in isp soft and application working in factory io to my students. I googled a lot and found some softwares which make virtual serial ports for a given serial port but they don't work and soon hang Please help me I am in a great need of it. Thanks in advance.
  25. Hi All, Am trying to communicate and make In-Sight bar code reader to trigger through MicroLogix 1100 with RSLogix 500.  Does any have any info as to the steps to follow.
