  1. Hi everyone, did anybody do rs485 communication with Non-Protocol Communication of Mitsubishi type FX3G-485-BD via sensor supppor rs485 ..help me,thanks  
  2. I have a fx5u plc connected to 2 keyence sr 1000 qr code scanners using plc link. On random times the plc error light will light up and all ethernet connection will be disconnected and i cannot connect to the plc with gx works 3. If i put the plc in stop mode tho i can connect to the plc. I do not know what error code is causing this because each time i connect the error code is missing. The problem starts when the plc is in run mode. Can anyone help me with this as this is a persistent bug that keeps on happening in my system?
  3. Hello everyone, I am new to Mitsubishi PLC. My device is  IQ-F series FX5u-80 and GX Works 3 to set up parameters using ST. I need to implement a function that waits for a confirmation signal in order to continue to the next step of the program.  I though about another way by using a delay function instead of confirmation single for testing purpose

  5. Modbus Addressing in Weintek HMI

    Modbus addressing in Weintek HMI to poll data from Temperature sensor through RS485. In my system i have connected Temperature sensor to I/O Scanner has output in terms of RS-485 which directly connected to COM3 Port pin. No. 6 (as Negative) & 9 (as Positive) of HMI (Model No: MT8071iE) and HMI connected to PC via ETHERNET. I want to read temp on HMI screen via MODBUS protocol. So, can you please provide me instruction about addressing of MODBUS register in Easy-Builder Software so can read data of corresponding register. Because when i do compile i got an error like " Device no Response". I hope i will get reply from your side as Fast as possible to overcome this problem. Thank you.
  6. Parity Error

    Any one  have any experience to due with Parity Error when RS485 input can't get? Below is the circuit trace i get. It shown me that Parity Error when input signal from my device. But some of the time I can get the input message completely. Sometime can't. Is there any way to solve it?  
  7. Hey guys, I've question about Transient transmission (TT) via CC-link using FX5 as a master. According to chapter 4.3 in "FX5 User's Manual (CC-Link)" only way to access TT is via computer with GXworks3. Is there some workaround to use standalone FX5?   Thanks again
  8. Hello Everyone, I am struggling with interfacing Incremental encoder with FX5U PLC, Does anyone have parameter setting and sample program for same. i am unable to fetch counts...   Encoder: 500ppr, 24V line drive, A-B phase,  PFA datasheet
  9. i am new in plc programming . i know the basics difference between the rs232, rs422, rs485. but i am little bit confused in it. so i have the following question regarding these terms. 1.  can these protocols communicate with each other i mean rs232 can communicate with rs422 or rs485 and same. 2. my plc has port rs422  but i can connect it with my laptop serial port which is rs232 ? 3. what are the main important points that kept in mind during communication or cross communications.   any help will be greatly appreciated.
  10. Does anyone have any experience with the recently released user web interface for the iQ-F and iQ-R series. Supported by GX Works3 version 1.047Z or later, the firmware Version 1.100 or later. We have the sample user web interface running in a FX5U, its working very smoothly. I am currently looking into how to edit the html page, does anyone have any tips or useful tools/resources that I could use to work things out.       iQ-F Customer News regarding FW Update 08-2018.pdf
  11. Dematic PTL

    For the Dematic PTL (Push To Light) systems, does anyone have any information on the protocol used.  I'm assuming it's RS-485 based since the buttons use MAX1487 drivers. What I'm looking for is if anyone has a starting place to look at the handshaking or messaging.
  12. FX5U Modbus-TCP Server (Slave)

    Hello everybody. I need a solution for Modbus-TCP server on the PLC. With the FX3U it would work with the FX3U-ENET module. The internal interface of the FX5U should actually be able to work with the library of the FX3U (FX3GModbusTCPServer_GW2_V100) or not? Because a socket connection is now possible. I would be happy about suggestions. Dave
  13. Hello Everyone I have a problem to connect FX5U with Inverter Mitsubishi D700. ( no  respond from inverter) . I did read and following the manual. Could any one can help me?
  14. Hi ! I have to Control and Read an Masss Flow Controller (MFC) MKS MF-1, I have give this one an IP Adress (10.46.103.75). How can I Control it over Modbus TCP? I found in GX Works 3 in Tool/Predifined Protocol Support function the Modbus Menue, but i have no Idea how to Config it, i have no Idea how Modbus works..... Have someone an Example for a Configuration? 
  15. NX-105 Received Data

    Hello,  PLC: NX1P  Comm module: NX-CIF105   I am running a serial (RS485) network to control several motors. As a trigger for to read the serial port I am using the ( Ch1 Receive Data Exist) bit, which is an internal bit that's ideally should be energized when there's data in the Receive buffer. However, this bit isn't reliable at all. I am reaching out today to figure out if there's another way to trigger the receive command ( preferably without a delay)    thank you all  Cheers! 
  16. 1ms TON and TOF GX Works 3 FX5U

    Hi everyone I'm new to FX5U, 'cause I previously used Q-series PLC. So, is there any possibility to make on delay timer with 1ms PT?
  17. Hello, I have managed to send output to a terminal using a serial channel.  I have not been able to send data from the terminal to the Mitsubishi PLC. I am not using terminating resistors but I have a slow baud rate of 4800.  I am just using regular wires (1.5mm square) .  I think the hardware is okay as I can see the output from the PLC on the screen. Attached is the code.  I just send from the terminal the character 22 every second, I hope this is not too incomplete to get some help.   The plan I guess later is to interface with LabVIEW probably using Modbus but I need to try to get this working first.     UL9.gx3
  18. I have the following array received from the RS232 port: RD_data[0]=H0020 RD_data[1]=H0030 RD_data[2]=H0030 RD_data[3]=H0030 RD_data[4]=H0031 RD_data[5]=H0035 RD_data[6]=H002E RD_data[7]=H0032 RD_data[8]=H0036 which means " 00015.26" how do I convert it to the real number 15.26 in FX5U PLC? SOLUTION: I used BTOW to set the data for EVAL instruction  
  19. Hi, Many Programms we have are written in Codesys and in ST Language  and now we have a FX5U and I'm trying to Convert some of them. But the both Systems are different, I miss the Librarys like util.lib and FB like RAMP_REAL, BLINK, LIMITERROR which are in Util.lib. Are there Librarys like util.lib for GX Works 3 ? Is it possible to convert Ladder to ST? (I dont have any Idea from Ladder and I'm new in Programming)  Have someone Sample Programms for me for Training?

  22. Morning Guys, For my latest project I need to read a gas sensor via 485 from a Momentum PLC. I've been through the help files, but they seem to only raise more questions than they answer, they only seem to reference PLC -> PLC comms. I've had a play with the 'MBP_MSTR' & 'OUT_IN_MBUS' function blocks, but i can't seem to get anywhere, Has anyone got any examples of reading in data via 485, or can anyone lead me in the right direction?
  23. Good Morning. I'm budgeting an application with the following FR-F720, FR-D720, GS2107 wtbd, FX5U-32MT / ESS equipment, I would like to know what network configuration for the application, I need accessory boards for the inverters, what physical arrangement it would be better for this application, which network would be used in the application, besides which function do I need to read and write in the inverters? Can I do CC link? If possible indicate materials that I can use to configure this application.
  24. RS485 Async

    Hey guys I don't have much experience in PLC serial communication and I'm tasked to integrate 6 OP-905 scales with our EATON based control system. The scales are rs485 asynchronous serial communication, my concern is that if the device is not designed to be an RTU then I cannot use modbus. And if that is the case how do I talk to multiple scales using the async protocol. Has anyone done this in a similar platform? 
  25. Operation error

    I am developing an application with fx5u with inverter d700, it fails to send a command to the inverter, only running the application and monitoring the clp does not appear to fail, only when it sends a command. Attached photo of plc configuration and error. Do you have any secrets to doing communication, can I do it with a normal network cable? I'm doing with just one inverter, as the terminator should be at 110 or 330 ohm.
