  2. CC-LINK CONNECTION

    Yes, that function should help find issues with a station connection / transmission setting. 
  3. Today
  4. TIA_Portal_V16 different variants?

    have not used Siemens in a while, but need to dump modified project into one of machines. modified project was done in different version so i need to get the TIA portal v16. I notice that there are two download choices - unified and .... non-unified? what is the difference? both seem to be the same size...
  5. Arithmetic behavior causing a quick zero

    Thank you! I will study this.
  6. Conveyor flow logic

    Is this file still available? 
  7. Right, that means your PLC "owns" those devices.  Most I/O devices do not permit many, or any, configuration changes while a scanner owns them.  You will need to inhibit those modules in the I/O tree to be able to write configuration attributes.
  8. Are you the Steve Bailey that worked on a project with me for New Jersey Transit?

      Steve Bailey

      Yes I am. What are you up to these days?

  9. Wrong values on FX3U

    Topper !!
  10. Currently router I am using here doesn't support port mirror. I have requested team to get the router supporting port mirroring. I should get that sometime in next week. I guess till then I won't be able to debug "Embedded service error" in detail, I am stuck here, I guess.  "Owned" by something - didn't understand this?  Studio 5000 I/O device tree snap is attached. Device 1 and Device 2 are the I/O devices in which we have implemented Ethernet/IP communication.

  12. CC-LINK CONNECTION

    Thank you ! I was able to get it linked . I'm new to CC-Link , is the Operation Test tab in the CC-Link Diagnostics how you test your connection between the PLC and other station connected ?
  13. Wrong values on FX3U

    I don't know why, but it seems that I had not yet found/seen the Structured Programming manual. I had a few other manuals but not this one 😅. I understand the functions better now. Thanks! The D8340 "bug" has also been solved! Just like the C250/C251 problem, I found out that the Chinese clone has a different device number for the actual pulse count. I used a switch for enabling a DRVI command while scrolling through the device list until I saw a value changing. For this PLC type I have to use D8132 instead of D8340.
  14. SMS messaging from a CJ2M-CPU31

    Thanks for the reply - will have a look at this over the weekend.
  15. Tracking,

    Thank you so much guys, the information what you guys shared are very useful. I made a little example program, to check how is it working. Its working properly I guess. @pturmel Could you please share with me an example ladder logic, about your solution. Some part of that dispriction is not clear to  me yet. Thanks ahead.
  16. CC-LINK CONNECTION

    Did the error start suddenly or is this a new system?  Check station & baud rate settings on each device, and resistors where appropriate. 
  17. SMS messaging from a CJ2M-CPU31

    This isn't supported, you'll need to utilize a 3rd party service like textbelt.com and program the PLC to utilize their API. I don't have any examples for the CJs, just the NJ/NX PLCs. If you only need 1 or 2 different SMS messages there are some products that can send out SMS messages based on digital inputs(RT100 for example). Alternatively many cell modems support AT commands which are very easy to utilize with socket services and allow you to customize the recipients and message contents.

  18. CC-LINK CONNECTION

    Hey guys, I'm having trouble getting my data link started in GX Works3 . Does anybody know how to get rid of the errors for the slave stations ?
  19. I just discovered that my Mikrotik router can do packet captures for me on selected interfaces and stream the results to a Wireshark instance on my laptop.  No need for the port mirror at all (but HW offload has to be disabled on the affected ports).
  20. Tracking,

    If you have to track in arrays of larger data structures, using ring buffer techniques can greatly reduce CPU utilization.  Using the shift instructions, or COP for shifting, is quite expensive.  Instead of shifting, you add to an integer subscript for the load point to manage where you are in the array.  And wrap around the end.  For physical items on the conveyor a known distance downstream from your load sensor, you simply add to the load point subscript the constant for the distance (in array elements), wrapping it around, too.
  21. I doubt this will be much help, but AB drives usually have a Status Word, Command Word and Data Links between themselves and the PLC. The Powerflex Manuals will describe the Status Word, Command Word and Data Links in detail.  The trick will be to find how in Schneider Memory / Tag Structure the EDS has mapped them. The HIM of the drives will also be useful as they will tell you when you have supplied th appropriate Stop/Enable signals to allow the drives to runa t all. Speaking of which, have you run the drives from the HIM to confirm you're enables and stops are wired correctly?
  22. Tracking,

    I've done this with covneyors and no encoder just a once per revolution of the driven shaft prox.  So 5 meters might become 500 or 5000 pusles of the sensor. Then create an array of length 600 or 6000.  I was usually using DINTS because I had to track more than just good/bad. Each prox pulse I check the bad sensor and load position 6000 of the array with a 1 or zero,  After that I COP Array[1] Array[0] moving everything one position. A little trail and error tells me that due to rounding errors and such the unload/stop position is actually 98 or 997 not the 10 or 100 I calculated. Hope this napkin description makes sense.  I'm sure it can also be adapted to using the encoder values. 
  23. No question about that at all. But I am often not on-site, so a port mirror that can be configured remotely has great value.  And, sometimes, simply moving connectors masks a problem.
  24. Port mirroring is complicated. Either find an old hub or use a sniffer is the easiest. I use shark tap. 
  25. Troubleshooting problems in cases like this.  Most modern managed switches have features to help technical staff connect wireshark to specific ports, so that sources of bad behavior can be examined unfiltered, and without relying on an intermediate two-port switch. Actual DLR, though, is awesome.
  26. Last week
  27. Has anyone done SMS messaging from an Omron CJ2J-CPU31 PLC? If so could you help please. Omron here in Oz have not had any experience doing this and are unable to assist.
  28. Hi, I'm working on Mitsubishi MR-J5-70A amplifier, and need some advice on selecting fuse size. Main power is 1ph 240VAC, and in the manual, it says that for main power, 1ph 240VAC for rated current of 6.5A, and for controller power, 1ph 250VAC with rated current of 0.2A. will it be ok to use 6.5A fuse for main power and 0.2A fuse for controller power? or what calculation or table do I need to use to select proper fuses?   Thanks,

    thank you, my problem has been resolved
