I initialized the plc  like photo can any one help me? sorry for my English
  2. Hello all, I need to read device memory mostly I need to read R registers from PLC L26. I read device data, but inside of table, I can't find R or ZR registers. Can you help me?  What I did wrong?   BR KS  
  3. Hello, We have a FX3G connected to a FX3U-ENET-ADP inside a main cabinet. We are then using that master PLC to collect data from 2 other fx3g plcs in a node:node serial network. I was assigned a small project of pricing out some wireless adapters so we can upload/download to the two slave plcs. My question is, is it possible to upload/download programs to/from the slave plcs through the ENET adapter and serial network in the main plc? It would save us some money if possible. thanks.
  4. Hello!  I was trying to set an value on "d" register to use him like a parameter. We are talking of connections of m0 on the next image:   the system works as follows: when pressing a button (M0), it moves the variables typed in the HMI (D14 and D16) to D10 and D12, at the same time that it takes these values and generates the parameter of minimum (D8) and maximum (D60). And its works perfectly, at least while on. When the clp is turned off and on, the variables are reset to zero, even if the only way to change the values is to press the set button again. What can I do to make it keep the information that has been moved?
  5. Mitsubishi PLC with Fernhill SCADA

    Hi, Has anyone here has experience of using Fernhill SCADA with Mitsubishi PLC FX3U Series? I want to monitor PLC's data in real time through FX3U-ENET-ADP ethernet adapter using Fernhill SCADA software. Thanks in advance for the answer.
  6. Hello All,   Semi-noob here with Mitsubishi PLCs. I'm starting a project in which we are upgrading an existing A Series PLC with the Q.  Is there a datasheet somewhere that lists compatible software within Mitsubishi's lineup? I had no luck in searching their site.   Also, (in the same project) the existing network uses DeviceNet. I have the Q series compatible card for that - but within what software does one configure the network?   Thank you.
  7. Error Indicator on FX3U-ENET-ADP

    Hi all, I have finished installing ethernet adapter module FX3U-ENET-ADP on the FX3U-48M PLC. From the ethernet module, i connected it to a wireless router and then i am planning of connecting to the ethernet module using GXWorks 2 on my laptop through wireless router. On the ethernet module, the error indicator LED is on (red). From the FX3U-ENET-ADP, it means that there might be setting or hardware errors.  I am asking if i have missed some steps on the installation process and if any of you have experience with similar problems. Thanks in advance for the answers.
  8. 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 .

  10. 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?  
  11. 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..
  12. 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?
  13. Hello Mrplc's members I have a Korean version " goldsec Moj2" of Mitsubishi plc A0j2 I need to know the right software for it And how to get it I tried GX Developer but it didn't work because it have only A0J2h type And I tried melsec medoc (version 1.64) but it didn't have A series CPUs

  15. 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. 
  16. 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
  17. 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
  18. Hello Sir/Ma'am, Hope you and your family are safe in this Covin-19 Pandemic.   One of my client have a machine in their ceramic industry which has Omron PLC System. Here I am describing the PLC Hardware Structure. (CP1H-X40-DT1-D-SC) + (CP1W-40EDT) + (CP1W-DA041) CP1H-X40-DT1-D-SC (Main CPU Unit) CP1W-40EDT (First Expansion Module, on right side of the CPU) CP1W-DA041 (Second Expansion Module on right side of the CP1W-40EDT)   Client shutdown the machine before a month due to Corona Pandemic, and today restarted the machine.   Now the problem at the restart of machine... Analog Output of 0-10V DC are not sourcing from the attached analog output module for any of channels. (Used to control speed of AC Drive) We have checked the program, and verify that the program is moving the value in analog output register address, but still no output signal at the module.(Checked Using Multimeter) We have same machine at another factory so we have tried to replace the all 2 expansion module and observed that the first Digital Module is Working properly but only last analog output module is getting problem again.   I don't know much about OMRON PLC Programming so seeking for the help regarding this.   OEM have moved the data in CIO 106 for generating analog output, as well OEM has move #8099 in CIO 104 and CIO 105 at the first scan of program. I don't know very much about this programming, that's why i refer some manuals but didn't succeed yet.   Kindly help me out if possible... I have attached backup of program as well for reference...   Thanks...   Bobin Feeder.cxp
  19. 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.

  22. 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 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.
