  1. 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.
  2. Delta eserver problem

    Hi Guys, Im using delta eserver to get data from access and there is an error. How do you solve this? Eserver is installed on windows server 8  
  3. Hey everyone! New member here, and this site has always been a big help!  I try to help other folks too, but a lot of guys are super quick on here.   I've got a problem using some obscure components. I inherited a sensor network at work that uses Panasonic S-Link and I need to read them from a Q-Series. Panasonic makes a module that slots into the Q Series called an SL-VMEL-Q that I have.   My question is:  Did I do everything correctly on my Mitsubishi side? I put it into the parameters as an intelligent module with 64 points and I put the correct address in for the start I/O. Is that all I have to do?  This is the first time I used a module that wasn't on the drop down list when you add one in GX Works 2.   I can read and write to the buffer memory, but I can't get the unit to send to or receive from the sensors. I think the problem is that there is no end unit on the S-Link line (I don't know if it's just a terminating resistor or what), but it previously worked without one, so I can't be certain.
  4. Hi everybody, I have a GT2310 communicating with the Mitsubishi F800 VFD. I am using the Freqrol 800 communication driver, connected to the RS-485 terminals of the GOT and on the F800. The comm settings are the same on both devices. I also tried to use the “auto negotiation” setup. I have communication between the two devices. I can read and write to F800 registers.   Anyways, The GT designer diagnostics is complaining about a communication error in the system alarms. The error can be reset but it will appear again.   This also happened when I created a new, empty project where just the communication was setup as described above.   Did anyone experienced the problem and how to troubleshoot / solve this?   Best regards
  5. 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?  
  6. 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.

  8. 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.
  9. GX Works 2

    Hello everyone! Can anyone suggest to take all the Input and Output (digital) status at a time in a single file for backup in gx works2 in FX2N PLC. I need to confirm that all required IO are in perfect condition before start operating the machine. Also I plan to design a troubleshooter to find problem.

  11. iFIX restore problem

    Hi, I have .fbk backup file of iFix aplication (i mean).. When I try to restore it by "Backup&Restore Wizard" in part where I "Browse" the way to Backup file and click on "Next" is problem. Pop-up window show -> "Bad file format. The archive file may be an old version or a wrong version in header signature or is not a Proficy iFIX full backup file (.fbk)" ....  My question is = Is possible to find what of version is my backup file ??? when i suppose this error mean i have installed wrong version of iFIX sofware (my version is iFIX 5.5).. Or is no problem of my iFIX version ?  Thanks
  12. Hi, I have some trouble with a CJ2M-CPU33. My client did a backup to memory card earlier today, and after this we did some changes through remote link. Now the client wanted to restore the previous backup to the PLC and has done so, but the system would not function correctly. After going online on the PLC it seems like the PLC is stuck in "Stop/Programming Mode". When trying to change to "Monitor" or "Run" mode a dialog comes up containing the following message: "Failed to change the operating mode. The operating mode may be still changing in the PLC."  - All the dip switches are set to off after restoring backup - The PLC has been rebooted  - I have downloaded the application again through CX-programmer  - Verified that the PLC is set to start up in "Monitor mode" But nothing helps. The same message comes up when trying to change the operating mode.  Hoping anyone can help to resolve this issue as it is very critical for us and the client. In advance, thanks for any tips or help received. Best regards Stian

    hey, I can send pictures to display on HMI. I want to define some places on the picture as if they can do something if they are touched but i don't know how to do it? is it possible through macros?(dopsoft v2)(delta sb07s211)
  14. 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! 
  15. Delta PLC Analog Noise Reduction

    Hello All, I am Using Delta SE Series PLC and 06AD Module for Pressure Transmitter. But Analog input get fluctuate continuously. Is anybody have program for analog scaling.
  16. 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
  17. Hello i'm new in all things about plc, i do a project for school and i use a festo fc 34 plc. The plc is programmed via serial port RS232 my pc not support a serial interface and i use a RS232 to usb adapter. when a try to download the program to plc give me a error: "ERROR: Cannot access controller".  What i do wrong.  Thank you in advance and sorry for my English. Have a nice day.
  18. I am trying to connect a Delta ASDA-A2 Servo internal motor encoder to a Delta DVP28SV high speed counter input.  I was successful in connecting the servo to the plc on position mode with an external encoder connected to PLC high speed counter.  Currently having trouble in finding the correct wiring between the servo drive and the plc to count the pulses from the internal motor encoder.  Attached are some figures from the servo drive manual. OA --> X0 is obvious, tried s/s to GND, COM-, VCC and VDD... no result. Any suggestion would be highly appreciated.  
  19. fx3u ENET card, ip change

    hallo all again, is there some way to change external IP (target one) using ENET-502 card without reinit via sending 1 to BFM1600? I would really appreciate it (time savings) but from little what i know it seems impossible :(   thanks in advance

  21. S7 300 Profibus fault

    Dear All, We are in need of your expert opinion. One of the nodes of our Crane's Cabin gives a station failure problem, due to which whole Crane shuts down. we have done everything from replacing Dp connectors to changing Profi cables, swapping modules with other stations, changing Power supplies but the problem remains the same. Following are the system details, 1. CPU S7 319 F3 fail safe 2. IM 153 interface module 3. OLM module for signal conversion fibre to profibus from main CPU.   We have several nodes after OLM but fault was persistent with 3 nodes. After comprehensive working, it came down to just one but still not diagnosed. I will also upload the diagnostic buffer if needed.
  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?

  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. QJ71C24N-R4 G.Input command

    I need some help with G.input and g.output commands. I have a Q04UDEHCPU and my slots are as follow: slot 0 - QJ61BT11N cclink slot 1 - QJ61BT11N cclink slot 2 - QJ71C24N-R4  2-channel RS4222/RS485   I need to have 2 separate RS485 stings going to different devices. I cannot find the way of setting up the g.output command. G.Output "Un" (s1) (s2) (d) "Un" says it is the start I/O signal of the module, but I am not sure what that means. What there be a different "Un" number for each channel?
