  1. Hi Everyone,   I have  NT31C-ST142-V2 and it has a prompt of "System Program not exist or incorrect." I am trying to transfer via NT Series System Installer but I am getting a time-out error. I have Xm2S-09 serial cable with ATEN serial-to-USB cable.I know it is not broken since I can still Upload/download on a CJ2 PLC. I just want to know what other things I can do upload a systemprogram. I have seen a comment on this site that he remove the battery then tried to upload again.   NT is almost 15 years old. I have a back-up program.   I can't seem to upload by this time for pictures of theH MI and the screenshots of software .

  3. Hi all,  I want to ask some questions regarding Ethernet Communication with FX3U PLC series. I have 2 PLCs of FX3U series (FX3U-48M and FX3U-64M) and I want to monitor its data (input and output) using ethernet communication in real time. My questions are: 1. Does FX3U PLC have ethernet port so I can connect it directly to my Laptop/PC? 2. If no, do I need to use FX3U-ENET-ADP and can it be used for 2 PLC or only 1? 3. What software do I need to use to configure the communication between PLC and FX3U-ENET-ADP? 4. Does this configuration change the existing PLC program? 5. Can i transmit the data wireless-ly using some kind of ethernet to wifi adapter and what additional hardware do i need for that?  
  4. Designed a SCADA System using VB.NET. Everything working fine but coming to performance getting 2 to 3 seconds delay. Using FX3U32m Plc with ENET Module for Data reading and writing. I am having 200 addresses to read. Using MX Component as communication interface between PLC and SCADA. Is there any alternative or solution for this problem. Using one timer to read all data and update properties based on received data.    Thank you..
  5. Real to 3 decimal points

    I'm fairly new to Mitsubishi and I am trying to limit the amount of decimal places of a real value down to 3. I am using a FX3U CPU and the only thing I see in the manual is that real values are stored with approximately 7 significant figures. Is there a way to limit the amount of figures after the decimal point to 3 without converting to an int value? Also does restricting the decimal to 3 points on GT works change to PLC value at all?
  6. melsec medoc error

  7. The CC-Link system on a machine has been intermittently dropping out.  Normally the Link Scan Time runs at a solid 87ms.  When the system "drops out", the link scan time will increase.  Sometimes double, triple, or go up 10x. It happens when the machine is running or when it sits idle. There are 33 stations on the network.  The same stations do not always fault but sometimes all of the stations will fault at once (as seen in the attachment pictures.) We have changed the main QJ61BT11N, the processor, the Q62N power supply, the main backplane (base unit), all cards on the main backplane.  Is it possible for one station or one of the cables to create a network wide problem?  Any ideas thrown at us would be appreciated. 
  8. FX3U-ENET Email Function

    Hi, I am looking for some guidance relating to the FX3U-ENET module. Note, I am only a beginner trying to learn about the FX-PLC as I go. My aim is to have various events in the FX3U PLC send an email with some information within the email text body. The programming of the PLC for the event sequence seems to be going well but getting the ENET module to send the message is my problem. I am programming the ENET module parameters using FX-Configurator which appears to take the commands and that seems OK Reading the ENET manual it appears that the email server, DNS server and Proxy Server, need to be within the same local network as the PLC. See the page I have attached that states that the "Access range of the Ethernet module" is within the local network, and that "the Ethernet module does not send and receive emails directly via the internet connection, the mail server sends and receives emails". So taking that information at face value, it appears I need a mail server and a DNS server? My question is that correct and is there any easy option to achieve this? I have had a play around installing hmailserver on my PC as my local mail server and it seems to work. The message starts to send but I get an Error on the ENET module, checking FX-Configurator diagnostics it says i have a C103 error,  DNS settings incorrect.• Check the DNS mail address./ Check the content of the DNS setting . So this may refer to the DNS server needing to be on the local network? Setting up a DNS server, let alone a mail server seems to be a whole lot of trouble and not practical for the task of sending email messages. Is there an easier option? Am I reading the manual correct relating to the servers within the local network? Any thoughts? Thanks
  9. FX3U-2HC through FX5-CNV-BUS

    Hi  I am currently working on a FX5U that is connecting to a FX3U-2HC through a FX5-CNV-BUS. I understand that you cannot pull in the FX3U-2HC into the Module Configuration, and that you just increment the module number of the FX5-CNV-BUS by one. I have tried doing this, but cannot get my sensor to pick up pulses. Does anyone have a sample program on how to do this? Showing the required BFM data I need to write to get the counter working.   Kind Regards Morne
  10. 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.

  13. Conversion from A to Q

    Good Evening everyone, I do realise that this has possibly been done before but quite a few years ago and the links no longer seem to work or links to Mitsi pages that are in Japanese, so please excuse me. I have soem A series PLC kit that needs replacing and I have bought all new Q series stuff to replace(where possible). I have been languishing a little on this project now for a few months but need to get moving. I purchased a GOT HMI and got a good deal on the HMI and the complete Mitsubishi Software Suite the local Mitsi guru said that was all I needed to get the job done. But afetr delving into what came inthe box it seems I need a A - Q Conversion Support Tool https://www.mitsubishielectric.com/fa/products/cnt/plca/pmerit/renewal/case/support_tool.html However I cannot find the software on any of the DVD's that I have and I cannot seem to find a download. So I am stuck now. Can anyone help point me in the right directon? Any Help greatly appreceiated. Thanks in advance.

  17. FX3U Stop Reading Channel Data

    Hello Everyone,  Need help with reading channel data of FX2N-4AD with FX3U Cpu. I have added all the logic and it works also. Problem is that, FROM function stop reading/fetching data from FX2N-4AD after some time i.e couple of hours and value just hang. Like 502 or something, untill you reset the whole PLC. What could be the problem. For the further info, -I have connected the FX2N-4AD on the right of fX3U-64M. -There are two extension blocks FX2N-16EX and FX2N-16EYR also added to the right of FX3U-64M -Order of mounting....FX3U-64M > FX2N-16EX > FX2N-16EYR > FX2N-4AD > FX2N-4AD   I have tried using the 2nd special module connected at the end, but It showed similar problem after few hours of running. THis shows that both Special blocks fx2n-4ad are okay. There is something wrong with PLC maybe? Please help

  19. Hi all, I want to connect FX3G PLC to a network. So I have installed FX3U-ENET-ADP to the left side of the FX3G PLC using FX3G-CNV-ADP. Can someone help me how to change the IP address of the PLC according to my network IP address (let us take it as 192.168.0.50). So now I want to configure the PLC's IP address as 192.168.0.30. I tried using the FX-Configurator-EN but I could not establish a connection with the PLC through it. Here are the snapshots of the process I followed.   But when I do the 'Connection test', I'm getting the following Error message. I tried to connect with both Serial port & USB. But it is showing the same error.   I'm aware that there are lot of discussions happened in this regard, but I could not find the solution part to the problem I'm facing. Kindly guide me please. Best Regards, Vijay

  22. Hello ! I am new to the forum and in the world of PLCs, I need to make a small home project and I have bought a PLC with the denomination FX3U-32MT-3V3I-8O100K-K-1 in e-bay (see attached picture) The seller does not provide  operation scheme, he says that to program it, gx developer can be used. I have GX version 8 installed on my laptop. The PLC has an RS-232 port and I use a usb adapter of the ugreen DB brand. Serial adapter cable with the Prolific PL2303 chipset. My problem is the communication between the GX developer and the PLC, when I make a connection test I see the error 01808201. I do not know ho to configure it  or what type or series it is,  i do not know withc cable to use, or whatever i'm doing wrong If someone can point me in the right direction, I will be very gratefull!!! Greetings from Barcelona! Joan

  24. Hi everyone; I want to communication Omron NB series HMI with Allen Bradley Micro 830 PLC. I don't know is it possible. İf its that possible, help me please..
  25. Is it possible to use FX3U-485ADP-MB as a serial port to send and receive user defined string/data to and from a computer? I have a FX3U-32M PLC and two FX3U-485ADP-MB adapters. I have been using PLC with one adapter as Modbus Master. Now i want to use both adapters, where one will be Modbus Master as usual and the other I want to use to send and receive data to and from computer terminal (Example - Realterm). I have a third party 232/485 converter which works really well. Lets me just describe my requirement straight forward. I want to display process parameters on a windows computer based user interface (UI) and also set some variables in PLC from the same UI. The UI has access to serial ports of computer.
