  1. HMI point table help

    I have a GS2107-WTBD-N (HMI) and I am trying to create a program that will allow our operators to change feed lengths (from a point table) via the HMI which communicates to a MR-J4-40A1-RJ Servo Amplifier. I am not sure how to upload my point table from MR Configurator 2 into GT Designer 3. In production we have a Rockwell PLC that they want to communicate with this Mitsubishi system. So my question is, do I have to have a PLC for operators to pick their "recipes" (point table lengths) or can I just upload my point table in my HMI program and let the drive do the rest? Secondly, how do I upload my point table into my program if it is possible. First year apprentice trying to accomplish this task. Any help would be appreciated.
  2. PLC to PLC

    Good day! They asked me to make an ethernet communication between 2 mitsubishi Q03UDE PLCs, without including an additional ethernet module, the truth is I don't know where to start, I would greatly appreciate your help.

  4. GT2710 screen not refreshing

    Hi All, and apologies for what is probably a proper newbie question. I have a Mitsubishi GOT2000 (GT2710) connected via DH485 to an Allen Bradley SLC500. Most of it works fine except for one base screen, which when opened doesn't get updated with any values. Opening any overlaying window screen will then causes the underlying base screen to then get populated. It's almost as though the first screen doesn't know where to get it's data from until the second screen is opened. As before I'm a beginner with this, so hopefully there is a simple setting that I haven't spotted. Thanks in advance for any advice.  
  5. I am trying to online edit a program in a MELSEC QCPU, using GX Works2, but I keep getting this error "A file which does not exist in the PLC was specified" <ES:010a4022> Few weeks ago I had just online edited the same program in the same PLC with the same steps with no problem. There had been no changes to the PLC after that. Just all a sudden when I try to edit yesterday I get this error. Not an expert in Mitsubishi, just started learning the basics. Connection to PLC is by USB cable. Steps I followed to connect to PLC:    -Online > Read from PLC    -Select PLC Series: QCPU (Q mode)    -Select PLC side I/F Serial Setting: Serial USB    -Select all target program to Read, then Execute I am editing the file that I had just read from PLC Steps I followed to online edit:    -Online > Monitor > Monitor (Write mode)    -Execute the function below when mode is changed: Checked all    -Edit the program (basically just deleted one -||- contact and drew back the line)    -Compile > Online Program Change Then Bam! error get! "A file which does not exist in the PLC was specified" <ES:010a4022> I had tried Verify with PLC, but all results match. Is there something I am missing? Help much appreciated!
  6. Hi fellow PLC veterans, I am new in the PLC world so please forgive me if my questions read dumb to you..   I am just wondering if there are any newer PLC machines that can: 1. keep the program even after its battery is completely flat or faulty  (Is this even possible?) 2. allow users to copy and save the program somewhere so one can install the program again without the need/presence of the machine supplier What tools/software may be required?   Thank you for reading and look forward to your response :)
  7. Hi, I'm looking for help with the string exchanging between GT25 and AB CompactLogix. I'm reading recipe data from SQL via MES interface to the local devices such as GD3000. I want to move the string held in the registers GD3000-3009 (20 characters) to the string tag in the Allen Bradley. The problem is that in the scripting I cannot enter the AB Tag, because when I imported the CSV with the string tags their data type is STRING, and the scripting in GOT accepts only numerical datatypes such as WORD, etc. Has anyone found a way to handle that?
  8. Hello, everyone I have to query a SICK distance sensor from an L26CPU via the onboard Ethernet interface. I have created a simple protocol which I start with the function block SP_ECPRTCL. Unfortunately it takes at least 25ms until the next telegram is started. The sensor responds within approx. 1.5ms. Does anyone know whether that works faster or is that a limitation when using the predefined protocols? Sensor manual:  OD5000, 8021391 (sick.com)  (Chapter 7.4) I am grateful for all the hints. Thanks and regards Dave SICK_Protocol.tpc Messaufbau_vTest.gxw
  9. Hello, I am started working on Gx Works 3 recently, actually want to know if I can access local labels from other program body or can call them to other program body?
  10. 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.
  11. 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.
  12. Hello! I'm trying to connect my QD75M2 with a MR-J2S40B1 Servo amplifier with an SSCNET cable. The problem is when I try to turn on the Servo ON/OFF on the Intelligent function in GxWorks2, an error occurs saying the servo amplifier is disconnected with my QD75M2. I'm confident that I've wired it properly. What could be the problem? Hoping you might help. Thank you.
  13. simple motion cam curve

    Good afternoon, I have a problem in an application for a rotary knife, I'm using a MR-JE-B servo to make this movement, while my material is powered by an inverter connected to a modbus rs485 network, with a 5v encoder connected directly in motion. I'm having some problems and I think it's my cam curve. I have a very high refeneration, and the system doesn't obey the size of the length I want the cut. It always cuts the same size, regardless of the configuration I use, it always cuts to 245mm. Put some photos, how are my settings. Grateful in advance, if anyone can help me.

  14. Hey! Is there any possibility to acces the PLC variables in GXWorks from another program? Like I want to read and write the I/O-s or Merkes in the Mitsubishi PLC from another program Could someone help me with this? Thank you!
  15. Hello! Is there any possibility to connect a Mitsubishi PLC to a program like Siemens Plant Simulation? With Siemens PLC I can do it through OPC UA protocol, or Shared Memory with SIMIT, or stuff like that. But I would need to do it also with Mitsubishi PLC. Can I use for example OPC Server? I couldn't find out, if Mitsubishi PLC-s have that function built-in. (I have a L02 and a FX3S COU, either of them would be great.) Thank you!
  16. My HP laptop will lose communication with Mitsubishi PLC occasionally after removing ethernet cable to download from WiFi. Our company limits the ability to use the wi-fi when I have an ethernet cord connected to my laptop, it has to do with security. If I am connected to the Mitsubishi PLC, then want to download another file from our autosave, which we connect through the wifi, I have to remove the ethernet cord from my HP laptop to enable the ability to go wireless, however sometimes when I attempt to go online with the PLC after I re-connect my ethernet cable, GX developer will not allow it. I can ping the plc and even go online with other PLCs on the network, but for some reason, the one I was connected to will not connect. I restart my computer and even re-download the file again from autosave but no joy. Its not until an unknown amount of time that it will allow me to re- connect, its as if I lose the socket connection on the plc and it needs time to reopen. I talked to our IT department and they have no ideas. Thank you in advance for any help on this matter.
  17. A1S68AD CARD

    Hello. I have a system in which an A1S68AD card is used, that card has been damaged . I replace that damaged card with the new A1S68AD card with same wiring and same setting of dip switch. But at channel number 3 there is a RTD connected which gives 4-20 mA signal. But in Plc at channel number 3 the data register is showing -2400 fixed value all the time and in actual the temperature is varying. But PLC SHOWS FIXED VALUE OF -2400. PLEASE HELP ME OUT.
  18. Dear all, I have a FX2N-20MR chinese semi-clon of a Mitsubishi PLC. It has only a serial DB9 port that cannot be removed or exchanged (which is possible in the Mitsubishi original PLC). I wonder if I can make a simple SCADA system using that port and just one computer. I am reading this post: https://forums.mrplc.com/index.php?/topic/9653-fx-series-and-modbus/ And I am wondering how I can do what it is suggested there in the second message:  to use a free FB block, available in GX IEC (but not in GX Developer), which will communicate modbus via a standard RS232 BD board. Later on it mentions a library called ModbSFX. That message is from 15 years ago so I am wondering if now there is some other way to do it, perhaps some other software has that functionality? I don't have GX IEC. I am a student trying to make a project so I would like a cheap and simple solution. Any help to do so will be very welcome. Thanks Regards Marcelo

  20. Hi guys, I am using a GT2107-wtsd HMI and a FX5U-32M PLC with gx works3 and designer3, i setup some simple ladder code to test that everything works, but i cannot get a normally closed contact to open when i press the button on the HMI and make the light turn off? screenshot below shows the code and the HMI buttons, when just looking at the HMI screen, all lights should be off with the exception of light number 2 as it is conected to a Normaly closed contact and i want it to open when i press the button on the HMI beside LT2 (light 2). I cant seem to get it to work.. please help, thanks.
