  1. S7-1214C All LED Blinking

    You can use a program called Nmap to run a ping scan. It will take a while and it helps if you know the subnet. You can use a BOOTP type utility to see if it's sending DHCP requests to see if it's configured to get an IP address automatically. I've never used a 1200, but if the CPU has a DP port, you can connect via a PC Adapter and upload the station to the PG/PC.
  2. SLC 100

    We have about 8-10 of these things in service. If you have or can get a copy of SLC Logistics, it will run on an XP computer (or virtual machine) and this adapter will connect via USB: https://www.plccable.com/allen-bradley-plc-slc-100-150-usb-1745-pcc-cable/ I think one of our electricians even got it to work using DOSBOX on a Win7 x64 machine, but that may have just been the PLC2 software.
  3. In these processors, some of the module configuration (especially analogs) is handled by writing values to the output image table. That's what the COP instruction is doing. It's writing to the module configuration registers on the PLC's first scan.
  4. Panel view plus

    On some PV+ HMIs, while it's booting up, there will be a small square lit up in one of the bottom corners of the screen while the rest is dark. Touch that, and it should get you to the configuration screen. If the folks who built the HMI for you didn't add a button in the project to shut down the runtime, the only other way I can think of is to create a new project with just the shutdown button on it and download that mer file to the HMI. The original mer file will still be there on the HMI, accessible and copy-able from the configuration screens. Once you have it, delete the empty shutdown mer and go to the startup menu inside the configuration screens to set it to run your original runtime on boot-up.
  5. ASCII Question

    Where does the data come from? Is there a reason to use a UDT instead of the predefined STRING data type?
  6. can not open a program

    What version is the PLC? Including minor revision. If you open the ACD file in notepad (or other text editor) you can scroll down through the first section and see the latest software version used to save it. If you right-click on the processor in RSLinx and select "Device Properties", you can see the version of the PLC. Major rev 20 was weird in that there are 2 (at least) earlier minor revisions that are incompatible with each other. The newest minor rev was supposed to sort that out. It looks like your software is 20.01. If the PLC is a newer minor rev, it won't work. I don't remember what error message you'll get.
  7. Unlock FB and FC @ TIA portal

    Sorry for your dilemma, but it's always against board policy to discuss bypassing or defeating copy protection or cracking passwords.   I am sympathetic since we have a number of machines here where the OEM is out of business and we don't have access to the source. Our only option is to treat the systems as black boxes that we can't really work with.
  8. Unlock FB and FC @ TIA portal

    I would assume it's the same as Simatic Manager: get the source code and password from the person who wrote it.
  9. Factory Talk Directory Blank

    We had that problem too when we had to change a computer name, but I can't find the notes I took about how to fix it. I do know you have to be logged in as a Windows admin and I'm almost sure you need the credentials that were entered during the FactoryTalk directory setup while installing the software. If you don't have those credentials, you may have to uninstall/reinstall the software.  
  10. M 810 lcd display doesnt work

    We've never actually used one of these. We bought one to test it out but never put it into service. Does stuff controlled by the ML810 operate? If so, it's just the LCD unit. Contact your local AB distributor for pricing and availability. They're not that expensive, so I would buy 2 so you have a backup.    
  11. M 810 lcd display doesnt work

    I think the LCD is a removable add-on unit. In that case, it's entirely possible the 810 is just fine and the LCD itself is bad. Have you tried unplugging the LCD and plugging it back in?
  12. Communication error

    Has this been working for a while and suddenly stopped working? There is a parameter that tells it what to do on comms loss: stop, fault, continue last, etc. You might check that. On most of our machines, the comms link isn't doing much for actual control (start/stop commands are hard-wired) so we typically set that parameter to "continue last".   
  13. 1336 plus (45 A /22 kw)

    The drive stopped when you sent a speed command other than 48Hz? Can you see parameter 28 change at the drive HIM when the PLC sends a new value to it?
  14. Our first responders used to have red mesh vests that they would wear while responding, otherwise there is no identification other than their pictures on several bulletin boards identifying the first responders by shift. I don't know if they still have the vests or not since I haven't seen any of them respond in a long time. Our more recent incidents have been on other shifts or have been over by the time I heard about them.
  15. 1336 plus (45 A /22 kw)

    Above 48Hz wouldn't do anything anyway since the max frequency in the drive is 48. Can the PLC issue it a speed command of 30Hz or some other value between 0 and 48Hz?
  16. 1336 plus (45 A /22 kw)

    Ok, I'm sorry, but I'm not sure what else to check other than the flow charts in the troubleshooting manual you linked. I don't know what kind of diagnostic tools exist for this protocol. Just to check, if you tell the PLC to send a different value to parameter 28 (preset frequency) can you see that parameter change value from the HIM?
  17. 1336 plus (45 A /22 kw)

    Let me back up a second. How is the drive supposed to receive its run command? From terminals, over communications, or from the front keypad? You said above that you pushed the button on the HIM to get it to start. Is that what you want? If it starts/stops the way you want it to but doesn't change frequency the way you want (in other words, it always runs at 48Hz regardless of what the preset is set to), look at page 45 of that manual. If it doesn't start/stop over comms (and you want it to), follow the process on page 41. Does the drive respond to any commands at all over the communications link?
  18. Allen Bradley Panelview .PVA

    I don't think so.
  19. 1336 plus (45 A /22 kw)

    Some of the drives we use have a multiplier built into the frequency command. For instance, to get it to run at 48Hz, we would send it 4800. This lets you send fractional commands. I would expect that changing parameter 28 while it's running would cause the drive to change speed while it's running. What values have you sent to parameter 28? What is the minimum frequency parameter set to?
  20. Allen Bradley Panelview .PVA

    I tried with PanelBuilder 2.6, 3.81, and 3.83. None liked it. Do you have a PBA file instead of the PVA file?
  21. 1336 plus (45 A /22 kw)

    Disclaimer: I've worked with some 1336PLUS drives, but they all use analog signals for their speed commands, not communications. Look at NO. 6, where it's set to Preset frequency. If the drive is looking at preset frequency, it will ignore other frequency commands. Also make sure your frequency command is between your min/max frequency settings. Are you writing to the preset frequency parameter #28? Page 2-26 of the user manual talks about this some. http://literature.rockwellautomation.com/idc/groups/literature/documents/um/1336s-um001_-en-p.pdf  
  22. recover program from plc-5/15

    If you need to program it and don't already have RSLogix 5, you may have to find a local integrator to help you, or replace the PLC. The last time we priced a license for RSLogix 5 (several years ago) it was VERY expensive. List price right now is $9980/seat for the Standard edition. By comparison, the Standard edition of RSLogix 500 and Studio 5000 are $2670/seat and $3640/seat respectively. They're trying to get people to stop using the PLC5. We have had a large installed base of PLC5s for quite some time, so it's often an easy upgrade for us to replace a mini-PLC2 with a PLC5 since we already have several seats of the software. If we were starting out new, we would not go that route.
  23. 1336 plus (45 A /22 kw)

    Which command from the PLC did it not respond to?
  24. Open-source HMI ideas

    You're talking about the PV Component, right? They've been discontinued. Do the newer PV800s offer the same functionality? I'm not aware of any others. I'll say that, at least when they were new, the web browser programming of the PV Components didn't work well for us. It was a little unreliable and there wasn't a way to make an offline backup.
  25. Download program to Micrologix 1400

    When you install RSLogix 500, it will automatically install RSLinx as well. Contact your local AB distributor for pricing on the different levels of RSLogix and decide which package you need and have the budget for.
