  1. GT Designer 3: Label import error

    Hello. When trying to import the labels from GX3, i keep getting an error saying the project cannot be opened. Has anyone encountered this error? Cheers
  2. It was rethorical. I don't mind Mitsubishi so much. GXWorks2 and now 3 is quite nice to program in. The hardware setup part though. A million settings? Crazy. The other week I was amazed/shocked to know that using an IO-module that allowed hotswap required an individual project to be setup in GXW3, and some interface addresses that needed to match. *siiigh* Siemens TIA portal 15 is better than it's reputation I must say. The HMI / SCADA part i cant comment on yet. Is allen bradley using IEC 61131, the standard for logical controllers? AB is not big here in northern europe. I have only yet encountered National Instruments stuff as part of the american plc business.
  3. Thanks for info. But I will just keep haggling with this and advise with the Mitsubishi contact on monday. To establish how many hours i can save, and how many i have wasted so far :)
  4. I am using a STRUCT / DUT on the PLC side, or rather two. How would you go about it on GT side?
  5. Okay. Seems like decent equipment. I'm using Mitsubishi GT Designer right now and am not so excited. Will see how that develops...
  6. Hi. I am looking for a way to efficiently add and edit objects created from a template. I had hoped to be able to paste directly from excel, but that is not possible. All i want to change for a template are the four numbers following the "M". Best would be to have a variable in the template that is included in all strings, but this is perhaps too much to ask? For example i want to change everything with M1477 to M1495. How should this be done? Cheers!
  7. Stay away from ifix is my advice. I liked cimplicity, also from ge, but never saw it on a panel. Beijer ix is also nice. There are server based solutions such as webport. If you go for beckhoff plc it has an integrated webserver and lots of possibilites. Haven't used it myself yet but it's a direction i want to go.
  8. GX Works3 problem

    Different ways are possible. Think for example about a TOF-timer and logic :)
  9. GX Works 3 Remote IO setup

    Hej Thanks for info. I was communicated that a second project was necessary if the hotswap function was used. It is not necessary in this project though, so we will try to configure the remote head station in the main project. Cheers
  10. GX Works 3 Remote IO setup

    Hello. I am told that the use of a remotehead IO-module demands that a separate project is necessary. Is this true? I am using a R32EN cpu.   EDIT: Just received word that it's because it's necessary for hotswap. Cheers // RI
  11. Change PLC model in GX Works 3

    Gold! Thanks, worked like a charm.
  12. Change PLC model in GX Works 3

    Hello. The project I'm in have decided to switch cpu-model from R04ENCPU to R32. It does not seem possible to change it in the module config / hardware view. I try to delete the old CPU, but cpu module cannot be deleted... Anybody know?
  13. Hi. This regards ventilation. A room has two air inlet dampers (pretty much like a big air valve in a ventilation duct). Only one is used at a time to regulate temperature in the room, and the other is then closed. When switching the inlet of air from one damper to another; i have not decided what method to use yet. I consider splitting the regulator output in two and let the one damper ramp down to this value, and the other ramp up.  When these values are reached one ramps up to the full regulator output and the other to zero. Not quite sure this is the best solution, and the code is not written yet :) Anyone done anything similar or has suggestions? Cheers!
  14. Gx Works 2 MELSOFT Library?

    Thanks. The thing is that i had to run next to the bicycle. So to speak. The project contained an old plc-system that I modified for it to work with a new test scenario. Timeline was short so that when I got IFM working it was "too late". The test had to be started and i reverted to the old software version which contained the old "writing hex-values to register business". Instead i was trying to "on the fly" create a gliding average function and do an online change. But in the end the test was completed, albeit with a stuttery load cell value, and equipment was put in warehouse again. Next time I'll use IFM only :)
  15. Rolling Average / exponential smoothing

    WSFLP i am having trouble replacing though. Considered SFTBL but it's no good.
