  2. Janitza UMG96RM RS485 Bus

    Dear All.     i'm a new user for Janitza. and i have issue related to RS485 actually, not to Janitza itself. i have one device (UMG 96RM), where there is only RS485 (2 pin only), no RS232, no USB, No Ethernet port. i'm trying simply to connect the device to the PC, via (USB to RS485) convertor, but i'm not able to do it. for me, this is the first time i'm see (RS485 2 Pins), usually there is Ground signal also. anyway, could you please somebody help how to connect? shall i add a pull up & pull down resistors at the device? and what is the power supply i must use? noting that, i tried many things, but still nothing happened.   Appreciate if somebody can help   Best regards.  
  3. Hi I'm trying to figure out how to use the OP320-A to control the relays on the FX1N-20MR. I have mastered the OP edit tool, but I havn't learnt how to use GX Developer. The FX3U and op320 by 485 setting youtube is a good start. Does anyone have a GX Developer project file available. Is there an OP320 and FX1N or similar that comes together, pre-programmed, ready to use. I know how to write C++ programs to send RS485 commands, but this GX developer looks complicated. many thanks Tim
  4. Good day, how can I send string data by buil-in ethernet. Maybe word 'TRIGGER,?
  5. FX3GA-60MT Modbus RS485 as Slave

    Can Mitsubishi FX3GA-60MT PLC be used as Modbus RS485 Slave? Any sample code or documentation would be very helpful. I am planning to communicate to Weintek HMI (Modbus RS485 master) to FX3GA-60MT PLC (Modbus RS485 Slave). Any other ideas would be nice. Thanks
  6. MC_Power_LD_FX5SSC Power Up Error

    I am using FX5U-32MT/DS, FX5-40SSC-S and the PLC Open blocks. I am getting an Power-up procedure error status signal. Any suggestions on how to track this down? Or should I do away with block and replace it with Un\G# codes. If so what should I use to make sure the drives are ready?

  8. Dear all, Do you have some ready examples for Mitsubishi fx5u where you use PID ? I use two analog input from 0-10V and two PLC output and I want to head 2 heaters. So how can I use PID autotuning? As I see in examples in manual, there also have other parameters, which I must set, except PID function. Thanks in advance . :)
  9. Good day, I need help, how I read data from Balluff BVS001C Identification over ethernet? Thx a lot
  10. Good day, I am new in mitsubishi and have a question about how build built in ethernet communication on fx5u fw 1.050 gx3 1.047 with smc ex260 sen1, where i need send 2 bytes and receive 4 bytes can u help me? I try to send data with this format 2#0000000100000001 and send by Ethernet Active Tcp connection library where I have added the external device configuration ip and port SMC EX260 SEN1, I think I needed use a CIP protocol and port 44818 or Ethernet/ip, maybe I need add a ENET module to use this communication between my devices? Thanks a lot for answers
  11. Hallo, i want to connect Omron PLC CP1E use CP1W-CIF11 to AD4329A with RS485 communication.  my wiring is CP1w-CIF11     AD4329A SDA-                  SDA & RDA SDB-                 SDB & RDB and until now, i cant get data from AD4329A. Do you have any clue for this project?   Thank you Riandanu PLC to 4329A coba.cxp ad4329aex.pdf
  12. FX5U comm with A1SJ71QE71N3-T

    Hi, does anyone has program example of ethernet communication between FX5U (GX Works 3) and A1SJ71QE71N3-T (GX IEC Developer). I need to read and write in both directions. Thanks
  13. FX5U Modbus communication

    Hello, It is necessary to manage 34 inverters via serial communication RS485. If a Modbus protocol is used according to the documentation, only one RS485 channel can be master. Then the maximum number of inverters will be 32. Can anyone share their experience on this case? Thanks in advance to all those who participated!
  14. Hi everyone, did anybody do rs485 communication with Non-Protocol Communication of Mitsubishi type FX3G-485-BD via sensor supppor rs485 ..help me,thanks  
  15. 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?
  16. 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
  17. Hi Friends, In My new project I have used two Delta PLC'S (DVP-60ES2 and DVP 14SS2) I want to communicate both through RS 485 Communication protocol.We have  tried communication trough manual help.But Master Slave device not communicating.We have checked for any error code in D1130 but it always showning "K0" value.here with I have attached screen shots and complete program for yours kind reference.Kindly help and guide us to communicate.   Master.pdf RS485 master trail 1.dvp Rs485 trail 1 slave.dvp Slave.pdf
  18. 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.
  19. 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?  
  20. 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
  21. 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
  22. 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.
  23. 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
  24. 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.
