  6. How to connect + Program wire encoder

    Hi all, I am not a PLC expert but can find my way within the program and would like to develop much more. For work (We sell industrial bandsaws) we have purchased a Posital Fraba wire encoder, and we would like to hook it up to our Mitsubishi FX3G PLCs to measure at what height the saw bow of the bandsaw is at that moment. Unfortunately I have little experience with connecting these things, as other encoders used in our machines are pre-installed by our factory. Below is described what functions the wires have. What I thought was the following: Pin 1 goes to an input of the PLC Pin 2 goes to + (or 24V) Pin 3 doesn't go to "Ground" as they describe, but instead to - (or 0V), which is technically ground Pin 4 and 5 we don't use, correct me if I am wrong. The saw bow goes up and down only, and I thought we don't need to use these wires.   I connected it like this, connected wire 1 to X0 on PLC and just to test I made the program read:   M8000 ------------------------------ C235 k99999   But the value stays 0, whether I pull the wire or not. So something is wrong, but what, I really can't figure out. Hope someone can help!  
  7. Hello everyone, As the title suggests I am trying to display on a GOT1000 the real time frequency that the inverter is running at. I have attached my CC-Link settings and the associated programming as well. I tried using the example program from Mitsubishi but I got lost. From my understanding I should be seeing the output frequency in W3C4 however, I am not receiving any data. Any help would be appreciated. 
  8. Mitsubishi fx5u SFRD instruction

    Dear sir,  Good day. I using SFRD instruction to read all the value stored when the sensor trigger. When the SFRD instruction is end(whe the word device number goes to 0), it will move the value to my store value and change my store value.  May I know how to stop it to overwrite my store value?

  14. GXWorks 2 Comment Translation

    Hello, I was wondering if any of you have experience translating comments. To be more specific, I have been tasked with translating all of the comments in my plant from japanese to english. We have many different series of PLCs, but they are all mitsubishi, and I will be using GXWorks 2 for 99% of them. I had the idea of writing the comments to a CSV file, Translate them there, and then just read them from CSV back into the project. I have tried numerous methods, but it seems the CSV loses format and isnt able to be read back into GXWorks. Some of these comment files have almost 10,000 comments. Do any of you have any suggestions on the best way to translate these comments over, in a more automated way than manually one-by-one.  Thanks in advance for any support you can provide!
  15. Hi All First ever post so forgive me if I do anything wrong. My customer has given me an FX5Uc PLC and a Delta DOP-B03S211 HMI. Comms need to be via serial. Ethernet not an option. I have configured the HMI as the Delta DOP datasheet(see attached) I have configured the PLC as: - MC-Protocol - 19200,8,1,Odd I however get an HMI error: - ########################################## COM 1 STATION 0: COMMUNICATION ERROR 3. READ ERROR No Response from Controller ######################################### I have created a simple page on the HMI  consisting of a push button (M reg) and a numeric display (D reg). When pressing the push button I can see the change in the PLC. (Transmission good) Any change of the D reg in the PLC is not reflected on the HMI. Confirms the message. I have tried all combinations of settings on both side but no joy. The PLC seems to be happy as it receives and transmits ok with no errors. Can any one see what I am doing wrong?

  16. Hi all! We have a problem with a Mitsubishi system. After switch off the machine in home position and back on, it resets the servo encoder value to 0.  I checked the servo parameters, and the Absolute encoder is enabled, the ext. battery is ok and no zero reseting in the program ( I think...). Is there a parameter I should check or some setting in the intelligent module? The system consists Q01CPU, QD77MS2 im., J4 200B amp with 6v battery, and HG-SR152 motor.

  18. Connect remotely to an OPC Server DA

    Hello, I need to connect remotely to an OPC Server DA. In my PC I have installed several OPC Clients but when I try to connect to the server (therefore located on another machine) I get an "access denied" error. How can I authorize the exchange of information between the 2 machines? Thanks
  19. Hi all. I've set up the analog modules and I've set devices within the HMI to move the value of d to the special registers for process alarm limits but whenever the plc is reset I'm losing the value. Have I missed a storing trigger or something? 
  20. SFC in Mitsubishi plc

    i have a question about SFC , if the step is active then processor execute code inside this step and writes on outputs true or false , then when the step deactivated the processor won't execute the code inside the step and won't write true or false on outputs. this means if output Y1 becomes true in activated step then it will remain true after deactivation , right ? in this picture if S41 is active , then M77 becomes true , then S43 becomes active , and S41 isn't active , then M77 will remain true and the processor won't execute S41 , or will becomes false then processor stops executing S41 .
  21. i want to know the role of M2 is to enable the comparison function or it's anded  with the output of the function. in another words if M2 is true and the output of the function is true then M3 is true, but what if M2  becoms false if it's anded with the output of the function then M3 is false , but if M2 stops the execution of the function M3 will remain true, so i need to know if it controllers the execution or it's just anded.

  23. Working with Strings

    Hi so i am learning to work with mitsubishi GX Works2 i am using the simulator, and the help anyway i was testing with strings and when i convert a unsigned word or dword to string it converts it as HEX values and also fill the whole thing with 0's can anyone help me or point me in the right direction with a manual, i do know my way around on AB and siemens but its harder to find help for mitsubishi, on the help for WORD_TO_STR, it says it should be converting to decimal but it isnt, is this a weird bug with the simulator?    
  24. Hi, I have a project and intended to use a FX3U PLC and E1071 HMI with a 1000ppr encoder. The project involves scan an object placed inside a blister cavity and decide it is good or bad by a sensor. If the object is good, then the input X007 turns ON and if the object is bad, then sensor doesn't activate X007. The blister is created in a PVC film roll and is in continuous process. A knife cuts the pack as per the size required, then the pack will move to a reject/accept station. The physical length from scan station to knife station is fixed If I use SFTLP, I can track the X007 bit until it reach the reject station and take the decision to reject or accept the object. But the issue is the number of packs from scan station to Knife station will vary according to the size of the pack. Bigger pack size has less 'Bit length of the shift data' (The length of shift register, n1) and smaller pack size have large 'Bit length of the shift data'. It is required to set the 'Bit length of the shift data' from the HMI, but the 'n1' of the FNC 35, SFTLP cannot take a D Register to set the value from HMI and it is a constant K or H. I have seen the operation on other machines using HMI to set the length of the Shift Register. but I cannot figure out the logic behind it. Could anybody please help? Thank you for your time.
  25. Hi all,  I am in the process of doing a project for some school work and need to do a SWOT analysis of the latest modular PLCs from Mitsubishi (R series), Siemens (S7-1500) and Allen Bradley (ControlLogix).  So I thought what better way than to ask the people on what they think are the pros and cons of each! Thanks for your responses in advance!
