  1. Mismatch analogue transmitter to FX2N-4AD

    Hi pturmel, Thanks for your suggestions about the ambient pressure. This Danfoss model is also used in the existing application so it won't be a problem to use it with the new controls. Today I've changed the program and made an offset [SUB...etc]  to have a more realistic value and it works fine so far. Thursday I will take the new installation live and keep the old controls as a back-up for a while so we have time to monitor and finetune during the day and switch back to the existing controls in the night or if it is not working well. So far thanks for your input, I close the topic for now. With best regards from Holland. Theo V.
  2. Mismatch analogue transmitter to FX2N-4AD

    OK, so I need to substract this enviromental pressure in the PLC program to have the proper readings. I was worried about the mismatch that i would damage the PLC input but it seems normal. That gives me a good feeling that the installation will work fine for a long time. Thank you for your quick reply pturmel. Best regards, Theo
  3. Hello all, I'm commissioning a project and connected a 2 wire pressure transmitter Danfoss MBS33 060G3039 to a FX2N-4AD module attached to a FX3U base. When I connect a 4-20mA simulator it all works fine, my signal is correct 0-4000=4-20mA and my HMI shows a correct value however when i connect to the Danfoss transmitter a mismatch occurs. It starts with a 5,5mA signal at 0,0 BAR so my HMI shows already 1,0 BAR instead of 0,0. It seems, when I increase the pressure, that is is a linear up going signal. somehow I think it is a hardware connection because with the simulator at the input it works OK but I can not find an other way to connect than inthe manual. Is there an other way with resistors or something to allign the impedance to the PLC module? Best regards, Theo
  4. Ha Theo,

    Met veel intresse heb ik je tutorial voor het het gebruik van de analoog i/o op de FX3GE gelezen.

    Je hebt het over het laden van de 3FX3GE_analoog.sul.

    Waar kan ik die vinden?

    Ik gebruik GX Works 2.

    Alvast bedankt voor je info,



    Hi Sudhi, I've did a conversion from an E- 1032 textterminal to GOT 2508VTB.. once with a conversion tool from Mitsubishi but that worked out that only the alarmlist was converted. However the E1101 ia a touchscreen so it might work better. I've sent my file to the Mitsubishi contact in Holland and I got a zip file with the converted file back (free of charge) Just try it and see what happens. Worst case scenario you have to rewrite the complete application. Good luck, Theo V.
  6. Mitsibishi Q restart automatic

    Hi Anootje, I suggest you place a temporary UPS in the 230Vac powerline to the CPU to investigate if the problem is caused in the powerline or in the PLC board itself. This has two advantages: 1) you can check for external powerfail to your CPU. If the incomming power is interrupted you won't have a problem with it. 2) An UPS also has filters for harmonic spikes etc. (UPS clean line out) Best regards, Theo V.
  7. Hi DWIM, Maybe this manual section 11 helps you out (see link above) and screenshot attached. Best regards, Theo V.
  8. Dear mr. Future, Visit the website of Mitsubishi electric to update your version. If you have a registration (license) of the software, the updates with new models are free of charge. You just have to sign up and register your version. If you don't want to update you can not open the project or if the terminal type is allready in your old version you can open the project however you might loose some functions that were added in the newer version. If you run into problems you can also contact your local Mitsubishi dealer. Good luck.   Best regards, Theo V.
  9. Problems backing up Mitsubishi FX1N-24MR-ES/UL

    Hi HYW6688, It should be upwards compatible to run the FX1N in a FX3G model bij changing the PLC type in the GX-developer software. Just try it and see whats happening.  Best regards, Theo V. (by the way, did you by chance allready checked the timers? and was it the problem as I mentioned?)  
  10. Problems backing up Mitsubishi FX1N-24MR-ES/UL

    Hi HYW6688, It seems that the timebase of your used timers is different. 10ms timer is 100ms timer or something. You should check if there is a difference in the range of the timers in the new PLC compared to the old FX1 model in the manual. I've attached a list of the timebase inside the FX1 type. I hope you have a manual of the new model to compare. Best regards, Theo V. Timer overview FX PLC.pdf
  11. Hi Janian21, The link below lead you to the E100 terminal manual (in pdf). In chapter 8 the alarm handeling is described. I hope this will help you out fixing this problem. Best regards, Theo V.
  12. FX3u-ENT Module.

    Hi Manna, As Collinsd70 says, fill in the subnet mask. General settings can be: or Remember to power cycle the PLC (switch off and on the power to the PLC) before network settings that are sent to the PLC will take affect. Best regards, Theo V.
  13. Hi Bryan, The link below gives you more info about the DIKD LED terminals (manual) the terminal has 3 stages. Bottom is +24Vdc, Middle terminal is - 24Vdc and top terminal is the switching input from the sensor to the PLC input. See the picture in the manual, the sensor is at the left hand side and the PLC input is at the right hand side. Best regards, Theo V.  
  14. FX3S-30MR/DS

    Hi Donny, The driver is on your harddrive. It is located in the easysocket Directory under USBDrivers. Check  C:\Program Files (x86)\MELSOFT\Easysocket\USBDrivers Best regards, Theo V.
  15. GOT and VNC

    Hi Andrei,   The VNC license cost in the Netherlands is only € 24,- euro so not much of a risk. It works not on all GOT terminals. Check before you buy a GOT terminal if it is suitable for using VNC remote acces. Example: I bought a GOT2308, it did not work with VNC so I had to buy a GOT2508 instead and that works perfect within the company network (LAN). For acces trough the internet we are using lately the routers from IXON which has a built in VNC server as well. This is a good combination. Remote acces trough your smartphone or tablet is possible this way. The IXON router is a little expensive, around € 500,- euro but worth every euro if your customer has a problem at te other end of the world and you can acces the terminal or PLC from your home or office. Best regards, Theo V.
