  1. OS SECURITY ISSUE

    HELP! I have been tasked with setting the security levels on this GOT 1000 HMI on GT Designer 3, i have come into a problem and this error message keeps appearing: "Delete OS from GOT since authentication does not work if OS for Operator Authentication is installed". I have recently with success set the password levels on a new HMI GOT 2000 and was able to create a log in and log out switch within the program so i understand the procedure.  Please see the picture below and i will appreciate any information.     Matt R 
  2. Hi All, I need access to a the Safety function blocks within a safety CPU using sysmac studio on a machine we are upgrading.. Is there a generic password available to gain access? Best Regards, Paul  
  3. Hi guys, my site uses mainly Mitsi PLC's & HMI's so not familiar with AllenBradley but i have two Micrologixe 1200 PLC's connected to Panelview 300 HMI's. The machines are twenty plus years old and now both HMI's are barely legible as the screens are so dim.  I want to upgrade the HMI's as they are obsolete but my problem is, the program within the PLC is Password Protected and i cannot read, upload or download to the PLC.  The original manufacturer has been taken over some years ago and no-one knows the password. They have sent me an old program that could possibly work which is not password protected, but i cannot download it to the PLC without the original Password. Can anyone help me?
  4. 2 PLC with 1 HMI

    Hello, I am going to be adding plc on press welding machine. the machine has PLC FX3U-16M and attached with 15 16points I/O module. is there any best way to connect 1 HMI with both 2 PLC ? 
  5. Hi, I have problem and hope if there is anyone who has same kind of problem, could tip me to the right direction. I have scrolled online for solution, but found nothing to solve this. Im makin heating/cooling control for radiator system. Basically temperature measurement that controls 0-10v valve. Pretty straight forward operation. Im having trouble getting PID control block to work on cpu. When in simulation mode PID works perfectly, but  when i download program to FX3u CPU, PID output stays at zero. No matter what values i give to PID, manipulated output is frozen. I attach some images that will show how its running. Tried few different PID's and results are the same. So im thinking there is some trick to the cpu to start executing this block. If you have some tips, i would be gratefull :). https://ibb.co/rpqFtLN
  6. hi All I am completely green in Mitsubishi PLC (i used to program siemens) but need kepware to connect to FX3U pls with ENET adp module. Could somebody pls help me with the very basics as kepware does not talk to the FX3U yet: What software do i need to read configuration/potentially do changes to FX3U and ENET? - is it free? How to check the port that the PLC is using - i assumed 5001 as default but it did not work- it is FX3 setting or ENET module setting? What kepware driver is best for the FX3 with ENET module? - at the moment ethernet driver seemed obvious choice to me Does ENET adp adapter can server only 1 connection at the time - is it hardware limit or something i can configure in the PLC? I will be trying to read strings from FX but how are these strings normally stored in mitsubishi FX3? - i found in the documentation that its either DSL  or DSH area - is it something that has to be configured upfront  or can i just use either DSL or DSH memory area? Massive thanks for any help upfront Regards

  9. Schneider Hmi Gxo3501

    We have Schneider HMI GXO3501. One of my collegue has uploaded a password in HMI and he has forgot it. Now we can't upload any things since it asks password for all.. How to recover it.? 
  10. Hello, I've been using Mitsubishi and Omron systems separately (in their own environment), and I am fairly new when it comes to connecting these two brands together(plc and hmi). I've been scouring the net for wiring diagrams for the cable connections and also the parameters to be set for a successful communication between those two components. can anyone point me at the right direction as everything I've tried so far has been a failed attempt of making these two communicate. here are the parts and my current settings if this helps: FX3U-64M FX3U-232-BD NB5Q-TW00B or better yet, is there a proper cable that I need to buy for this to work?
  11. I'm attempting to look at an offline PLC program to see device values (Ts, Ds, Ms). Is this even possible? Are device values saved when saving a program online? Program is for a Mitsubishi FX3U. Using GX Works2 v1.601B. Win10-Pro OS on the computer. I've an AB background (several decades), but only a couple weeks with Mitsu. Unfortunately, the person who originally wrote and maintained these programs isn't available. This is an easy process with AB, but I just hit walls in the Mitsu IDE. Can anybody help?
  12. Module Ethernet For FX3G

    Hi everyone, i'm just starting to learn plc mitsubishi. Today i got a problem about picking module plc. I want to communicate between FX3G and R04EN through ethernet. When i research it said only FX3U-ENET module can be connect to FX3G. But when i say it to seller, he said FX3U-ENET-L is a new update, and it can connect to FX3G @@!.  I don't know if what he said is true or not, can you guy give me some advice? The picture below is the documentation related to these 2 modules. Thank you very much and have a nice day. ^^!!
  13. FX 3U to Q CPU wireless Communication

    Hello experts, i want to connect 9 FX3U units with one  Q cpu base PLC unit over wifi, can you plz share the configuration details.
  14. FX3U to FX3U via wifi

    Good day fellow PLC ninjas! I have a question/ concern which I would love your opinions on. We have 3 FX3U PLC’s+ENET cards. Two of the 3 PLC’s move around in an EMS trolley. The other is a ‘base station’ with a GOT2000 connected via Ethernet. Base PLC IP = 192.168.1.11 HMI IP = 192.168.1.31 Carrier 1 IP = 192.168.1.61 Carrier 2 IP = 192.168.1.62 I have programmed the base PLC to use Active communication; we are using fixed buffer communication to send and receive data to/ from the Carriers. The carriers are set up as Fullpassive ‘slaves’. This part works well and the update time changes (using a counter in the base station) from 1s to 100ms (because it enters a different work station).  My issue is the following: using a network sniffer (WireShark), I pick up plenty of re-transmits and sequence number errors coming from the base PLC’s ENET card. This is troublesome and causes delays when the update time is required to be fast (100ms). I am sending and receiving 10 words of data. The wifi seems stable, and there is minimal noise in the area. The power has been turned down and the antennas used are suited well for the application. The antennas are at a similar height to minimize possible loss of signal. I have LOS (line-of-sight) to the carriers at all times; to at least one of the antennas (I am using 802.11n). Has anyone picked up issues or found settings which can be used for comms over wifi? I can easily do this using a S7-1200 Siemens PLC and have done so using 12x S7-1200 clients and 2 AP’s with 1 base PLC. I have also successfully done this using 8xFX3U client with a System Q base PLC. My suspicion is that the delay in reading and writing to/ from the BFM in the ENET card is causing this. I am not sure that if I change to a FX5U will help. The communication cards on the Mitsubishi PLC’s seem very limited. Does anyone have any technical details on the access times between the CPU and communications cards’ BFM? Help is as always, appreciated.

  16. Analog input melsoft (fx3u)

    Hello, I am new to the programming of logic controllers. I have a Chinese FX3U 24 inputs and outputs with analog in and outputs. I am trying to teach myself the basics of the programming but I am stuck at the analog part.    what I am looking to do is create a program so that when a 12v battery bank voltage drops and rises it can trigger other outputs. I have a voltage divider which outputs 1/5 of the input.    Thanks for your help in advance.  Ben. 
  17. Hi I'm trying to set up Modbus RTU communication between FX3U PLC and a weigh module. I would use the ADPRW command using 0X03 to read the 16 bit Holding Register but in the weigh module the Data Address/Holding Register of the value I want to get is 400047 - 400048. How to translate the value in 16 bit?   Thanks, Fabio

  23. 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.
  24. 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?
