  1. Best Diesel Level Transmitter

    Hello all, I would like to ask about the best transmitter to measure the level of a diesel tank. the tank is 2.5m high and 1.85m in diameter. I was thinking of pressure transmitter, however, it is not clear for me how to convert pressure to level or to liters. Your help is highly appreciated. Thanks
  2. Editable Timer in Structure Ladder

    Thank you Gambit. I see that there is no way to assign editable values to TON_E timers. I will manage to use the time as decimal values.  
  3. Hello Dears, I am trying to write a program in structured ladder. However, the timer will be adjusted by the user via HMI. I have no idea how to address this in  GX works 2 Structure, as it my first structure program. I also have no idea how to assign the time value i.e. seconds, minutes or hours in this case. Thank you in advanced.  
  4. GOT 1000

    Good evening dear all, I need to program a GT1455 which is in another country, however, I have no idea whether  it is possible or not.  If it is possible by any means via internet, please provide me with the manual for such case.   thank you in advanced.  
  5. Mitsubishi Inverter Protocol

    Hello Everybody I have a problem connecting FX3U to F700 using RS485 inverter protocol. I built the PLC example provided in the Data Communication manual to run the inverter, and then modified all required parameters in the inverter. Yet, as I run the PLC it says that the inverter is not responding. What could be the source of this problem? Is it a must to use twisted pair cables? as I am using ordinary wires.

    Aha I got it now. I thought it was built by the HMI Sofwtware itself. thanks a lot Crossbow. That really helped.
  7. Goot 1000 Figures

    Hello Dears, I am trying to do some pump sketches for a project, I tried googling some pics and found this HMI interface. Is it possible to do such pics in my case? what I need is a manual or a guide to start bduilding such interface. I did built an interface for a huge furnace, however it wasn't as professional as this one. Thanks in advanced
  8. 485 communication

    As  Crossbow  said above that You still need a memory card, the following Pic is from the manual of data communication showing the same thing. this manual will provide you with almost all information you need. This is a direct link to the manual http://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy997d16901/jy997d16901m.pdf
  9. FX3U-Inverter Modbus Commuinication

    I read the communication manual after I posted this Q and found out that Modbus via rs485 is only supported by the adapter FX3U-485ADP-MB.  
  10. Hello everyone, I have a problem connecting FX3U to F700 via Modbus, I wrote a simple program to initialize communication as the example in the communication manual and then programmed the inverter. I am using the fx3u-485-bd and the built in terminals in the F700, when I started the program, I noticed that the contact M8411 wasn't activated and the Register error D8402 has a value of 201 indicating hardware error. Is it possible to use FX3U-485-bd to start Modbus or I have to bring the Fx3u-cnv-bd with Fx3u-485adp-md? Thanks in advanced
  11. SLC5/01 to SLC5/03 Program change

    The program ran very well after inserting the proper I/O modules. Many thanks to You all
  12. SLC5/01 to SLC5/03 Program change

    Thank you Ken Roach, I will give it a try tomorrow and see if there are another faults.
  13. SLC5/01 to SLC5/03 Program change

    Sorry to say that, but I didn't see the Error description as it is my first time to deal with AB. I realised that the I/O is not the propper one for my SLC 5/03, I still need your help in configuring this I/O to work properly with this CPU. I also need to ask how come is that S:20=0 and s:21=2 indicating the error is in the specified routine??
  14. SLC5/01 to SLC5/03 Program change

    This is the error screen, I read that this error  (S:1/13) is happening when f the preset of timer T4:0 or other timers is negative. The screen is also showing the error rung and files which indicates T4:3. I tried to change the ACC of T4:3 to 0,, however, the fault is still there! One more thing is that when I am online and start running the PLC the ACC of T4:3 goes directly to 24000! any idea??    
  15. SLC5/01 to SLC5/03 Program change

    Thank You both  for your rapid reply. I will give it a try as soon as possible and will let You know about it.
