  1. NA Broken Line Graph

    I would suggest using the Trend Graph instead. Using it, you not only displaying real time logged data, but can load the data that is saved in the SD Card / USB Flash Drive. The data are tagged with timestamp, so should be easy to search for a certain day / time. Also you won't have issues with arrays. All tests must be done in a real device though. Otherwise, if showing graph in the HMI is not a necessity, I would suggest using the DataTrace function in Sysmac, which is on the PLC side. Here you graph and saving the data log inside your PC, so anytime you can load it up offline and show it.
  2. NA Broken Line Graph

    As you said, it is not working in Simulation mode (meh...) Graphing every 20 ms is quite intensive I'd say. The minimum value for interval-based update in the Broken-Line graph object is every 1000 ms. Sure you can reduce it using the condition-based update (like triggering it from PLC bit), but I don't know whether we can expect it goes faster or not. The only issue in using Broken Line Graph is that it is not a value vs time kind of graph, so if you want to achieve that, you must make the variable as an array. Say your variable is an integer array in size of 10, each index represents value at nth ms. Every new sampling, you need to shift values inside the array to emulate value vs time graphing. An easier solution would be using the Trend Graph which directly creates value vs time graph. But you need to plug either SD Card or USB Flash Disk to use it, since it is showing a real data log.
  3. CX-Programmer cannot download file to PLC

    DIP switch 5, when turned on, forcing the Serial Port settings to its defaults (such as baud rate, data bit, etc). When it is turned off, the settings are using values defined in the PLC Settings section in CX-Programmer that you download along with the program. These settings most of the time got jumbled and messy on power up if the plc backup battery is low on voltage. Maybe that was what happened
  4. Sending alarms with NA panel

    Thanks for this @Michael Walsh The only downside with the FB is that direct SSL connection is not supported, thus we have no choice but to connect the PLC to a local email server first. But I guess at the moment that's how it goes for other brand as well, though (Siemens for example).
  5. Direct Online Problem

    Yes. And I believe both will work.
  6. Direct Online Problem

    Omron RS-232 port pin arrangement is different from the usual computer RS-232 port. Make sure you wired it right like shown below (right is Omron side connector, left is computer side connector) :      
  7. EtherCat Configuration

    If memory serves, the Slave Address for the GX-JC03 need to be written manually. It doesn't got set along during downloading the program. After you download the EtherCAT settings, keep online to the plc, then right-click on the PLC unit in the EtherCAT window. You will see the option to "Write Slave Node Address". There you can write the specified node address to the JC03.
  8. The SEND instruction can do that. The Instruction Manual of that instruction describe the Host Link mode pretty well. That instruction only available for CP1L series and above though. You cannot use it with CP1E.
  9. Omron CJ1m - bluetooth connect

    Indeed Toolbus ain't documented, but using the Multiway program from Omron France, we can practically reverse engineer it. Granted you are a student, I'm sure you have the time for doing that. However, as Jay mentioned it is not really wise to do so. It's kind of wasting your time reverse engineering something that is undocumented, while you have something else that is already documented properly with the exact same usage (HostLink in this case). And guess what? The said "AC01" command was actually documented here : Surely it is not documented properly. If you want to try the command again, try sending "AC01" not as a String (in which you are sending 41 43 30 31 hex bytes), but send them as a raw hex bytes (so you are sending AC 01 hex bytes). I don't know whether that'll work or not since I never tried it myself. Good luck.
  10. Programming Incremental Encoder

    No, PULS and SPED are for outputting pulses from the PLC. To compare the encoder pulse count, you can use the PRV instruction to find the current pulse count, and use the usual compare instructions to produce the multiple output. Alternatively (and system wise better) you can use the CTBL instruction which generates the output as an interrupt, although the usage may not seems straight-forward.  
  11. Need to Origin a Stepper Motor

    Don't forget to set proper Origin Search parameters for the Pulse Output in the PLC Settings as well, if you are using the ORG instruction, or else it will always return an error. If memory serves me right, you always need to use Mode0 for Origin Search of stepping motor.
  12. Need help to connect to an OMRON NX1P to read DM data.  Any good suggestions?  Will be using Python finally but can troubleshoot with .NET.

      This is the reply when I try to read some DM data.. seems like whatever I send the error is the same

      My bad.. I got the FINS node wrong and thus cannot communicate.  No its working fine.
      A big THANK YOU to Innoaloe and Garry for pointing me in the correct direction!!


  13. G9SP Configurator

    There is no such CD program that ships with the G9SP unit. What Omron meant is that the serial number comes with the CD, should you buy the software. Of course entering the numbers printed on the G9SP unit won't work. It was never a free software. Faster way is (maybe) to ask Omron field engineers to come to the site... with charges of course...  
  14. Omron Servo Encoder

    I don't understand... you can use PRV2 for the HSC0. Why can't you use it on the HSC1 as well?
  15. C-mode hostlink library for NJ/NX1P or CP1L

    Nice find. The manual states that the FB not only supporting DM, but IR, HR, and LR registers as well.
