  1. FX54AD

    Hello all, Quick question - I know where to set the "number of samples" for averaging the analog inputs, but is there a buffer memory or similar that I can access without having to resend the application to the PLC ?    What I want to do is just fine tune one channel as the system is operational. cheers.
  2. MELFA ASSISTA COBOT

    Hello all, is any one aware of any good free training, guides, etc, I am using the RT Visual Box and I like it a lot, but need a bit more in depth info and manual is ok, but it does not explain things in great details more like a general view.   Many thanks.

  4. Change PLC model in GX Works 3

    Hello. The project I'm in have decided to switch cpu-model from R04ENCPU to R32. It does not seem possible to change it in the module config / hardware view. I try to delete the old CPU, but cpu module cannot be deleted... Anybody know?
  5. Hello all, I have the need for PLC to calculate a giving time shift pattern, so if I start Monday 8am on a 24h prod basis, and the production run is 48h, the PLC should tell HMI finish time is Wednesday 8am, that is ok, the problem is, Production stops from Saturday 8 am, and starts again Monday 8am. Thus if I start prod run on Friday 8am, PLC should tell HMI (Got2000), production finish time should be Tuesday 8 am. I can read RTC, compare, do maths, but how can I miss or not take into account Saturdays from 8 am till Monday 8 am...that is my problem.   Any thoughts, ideas, are all welcome. Thanks.

  7. Melsec Medoc K2N

    Hi, I have a client with an old K2N CPU configuration. Is there a communication module that I can use, so that I can upload the excisting program to my PC with my old version of melsec medoc, over RS232? We need the program to upgrade the PLC to a new type. But they don't have a program or a listing of the program.
  8.   Hi guys.   On our company we got several different PLC system but right now I´m focusing on a Mitsubishi Q-system with device-net master QJ71DN91.      We are going to make communication with SMC-JXCD1 controller for a actuator.   But I have no experience with DeviceNet and unfortunately there is no files, functionblock, or program examples what I can find.  Not even Mitsubishi or SMC had some for these two together so I turning the Question into this forum instead😊   Previously I´ve used profibus on a fx3U system and FX5U-Simple CPU communication protocol to talk with slaves in a network.    I got on hold of some old document from Beijer from where I got 3 functionblocks for devicenet.    1.DnInitiateQ  2. DnSupervisorQ 3. DnDataQ 4. DnMessageQ     So maybe I can have some help from these but I´m still not sure how to send/receive information to the SMC-nodes.   I´m a little confused about if I should use the master with I/O communication or  master with explicit messages?  The later I haven´t even heard of.    I was only thinking about creating array of word to receive and send info to the nodes.   But my knowledge of this communication protocol is very low.        Anyone know´s how to get me started?  Or can provide some kind of example in GX IEC or GX works.       
  9. Hi all  I need to view a project in instruction list format on Mitsubishi GX Works 2. On GX developer the shortcut is Alt + F1 or View tab then press instruction list.   Thanks 
  10. Does anyone know how to change the reading on Omron servo motor reading from negative to positive? The encoder is reading negative values when it is moving in the forward direction.  I am using 1S servo on NX1P2 controller on Sysmac studio software.  Please suggest. 
  11. CC-Link IE Protocols

    Hello, There seem to be a lot of different CC-Link IE protocols: CC-Link IE Field Basic CC-Link IE Field CC-Link IE Field Motion CC-Link IE Field Safety CC-Link IE Control CC-Link IE TSN This causes me some confusion. Are there as many variations of Ethernet/IP and PROFINET? Can you point me to a good comparison of the different CC-Link IE protocols? My understanding is that: CC-Link IE Field Basic: 100 Mb/s Non-deterministic? Good for non-time-critical communications (e.g., setting a drive speed) Implemented in software Traffic can co-exist with other TCP/IP traffic Max 64 stations Addressed by IP address Star topology I believe the other protocols are all 1 Gb/s, are deterministic, are addressed by station number, are implemented in hardware and each needs its own isolated network. CC-Link IE Control is used for communications between PLCs and robots. CC-Link IE Field is used for remote I/O and CC-Link IE TSN is used for even faster remote I/O communications. Please let me know if any of this is inaccurate. Thanks,
  12. I've set up 20 or so of my alarms under the 'User Alarm Observation' section. I then added an 'Alarm Display (User)' object. Will this object display my alarms when they come in? I'm noticing an Alarm ID section in the 'Alarm Display (User)' object section. What is this Alarm ID for? Can the 'Alarm Display (User)' object only display one alarm? That doesn't seem to make any sense? How would I got about configuring this object so that it will show all my alarms as they come in? Thanks!
  13. Does any one know any instruction that rotate the 1S Servo Motor continuously with angle(0 to 360)  and velocity control ? https://forums.mrplc.com/index.php?/topic/35459-omron-g5-servo-drive-rotary-mode/#comment-165564   Above link may be quite close to what i want. But I have no idea how to set it up   Simon        
  14. Hello and good day I have a Mitsubishi fx1n-14mr PLC controlling a band saw. The PLC is connected via a DB925 - MD8M cable to a Beijer/mitsubitshi E100 HMI for communications and as a power supply via RS-422. When powered on the display on the E100 panel fluctuating, i.e. the screen turns on and off repeatedly. If the main switch is then switched off, then on again the screens seems to stay on and the machine operates normally. The PLC has a built in AC/DC power supply and I suspect that is may be the problem. Is is possible to switch out the AC/DC module? To make sure that the E100 panel is not the problem I want to connect a 5V external supply to the port located on the back. Is it safe to have the RS-422 and the 5V external supply connected simultaneously?
  15. Hi, This is my first application working with a Mitsubishi HMI GT2107-WTBD using GTDesigner 3. Is it possible to have an Ack bit going from the HMI to the PLC when the operator acknowledges an alarm? I've found how to set up comments for alarms and trigger alarms but can't figure out how to link an ACK bit back to the PLC. Thanks.
  16. MR-J2S- Servo Driver to PLC

    I have a test station to test MR-J2S Servo drivers,  I am looking for something unique in the drivers to be able to save data about that test.  First thought was the SN, but i am not seeing any way to pull serial number from the driver. Only found it on the side of driver and really don't want people having to type it in , cause usually they type in the wrong numbers.  Does anyone know of a way to get the serial number out of the driver? or at least where it could be found?  Or any other unique identifier in these drivers?

  19. How can i limit MRJ4 servo load?

    Hello, I am beginner at servo and its driver. i am using MRJ4A driver and HG SR102 servo motor. i want to make my servo stop or alarm when the load is over the maximum load that i set by my self. what parameter should i set to limiting servo load even if the servo motor strength enough to lift the load.?  
  20. Hi all. I am new to Autonics and Mitsubishi. I am trying to read and write the data of an Autonics TK series temperature controller using RS-485 with QJ71C24N-R4 coupled with Q00UCPU. I have the hardware setup as attached images. Software setup are as follows:  TK4 Settings: Communication address: 01-99 Communication speed: 38400bps Communication parity bit: none Communication stop bit: 2 Communication Response waiting time: 20 Communication write: Enable Mitsubishi Intelligent Function Module: CH2: Operating: Independent Data Bits: 8 Parity Bit: None Even/Odd parity: Odd Stop bit: 2 Sum Check code: None Online Change: Enable Setting Modifications: Enable Communication Rate Settings: 38400bps Communication Protocol Settings: Predefined protocol Task to be carried out: 1. Read SV 2. Read PV 3. Write SV I have the address for the modules but I am not sure how to communicate or the program which allows to reading/writing. I had tried to follow the attached PDF but i cant key in the first line as there is a bit with "G450" which has an error stating "the device No. is over usable range" and  "An unusable device has be designated". I hope someone here could guide me in writing the program, or any reference for me to follow.  TK-Q02H_RS485_EN_Technical_support_180823_W.pdf
  21. Hi! We have a GOT2000 HMI with a Q06UDVCPU system. During an investigation, I found that the address on the HMI (for example D10120) and the address in the PLC (D10020) are different. The value is the same, it appeared instantly during monitoring, but when I searched for it, didn't find it (I couldn't find the D10120 in GxWorks2, and couldn't find D10020 in GtDesigner3). The HMI's address is 100 higher. I never saw anything like that. Where is this difference can be set? Knowing this, I can navigate in the program..it's just annoying.
  22. Simulation of FX5 in GX Works3.

    Hello gentlemen. I am working in a company that makes SCADA software, and needed to do reading/writing tests on MitsubishiPLC's, In this case I needed to do tests on FX2, FX3 and FX5. I saw that Mitsubishi makes available the GXWorks 3 software that is possible to do simulations of FX5 and FX5u in it, but I can't connect in any way to the PLC being simulated on the company network. I put the correct IP in the ModuleParameter\EthernetPort configurations, I write a simple read/write program in ladder, and I use Star Simulation, but when I try to ping the PLC, I can't find it, much less talk to it via VisualStudio . How can I connect this PLC that is being simulated in GX Works3 in an external program?
  23. serial input string

    Hi  I'm quite new to plc but very new to mitsubishi.   I have an input string eg G+002.7 which represents a weight. I wish to take in the input string then move/convert to int omitting first char,   On other plc's i have been able to use a modifier like d200[2] then the no of chars. How do i achieve this in gx works3   Any feedback gratefully recieved   Paul

  25. Motion Control

    Hi Everyone.   I have been tasked with changing out an older Flex Drive servo drive to a more modern Micro Flex drive in a machine that has an Omron CQM1H-CPU51 PLC.  I'm having a few issues but hope that i can gain some clarity around at least one of the hurdles Im facing from here. Biggest issue for me at this moment is My work hasn't yet purchased a programming lead for this PLC (or even the bits required to make one myself) but i have a feeling the control for the Servo is done via motion control in the PLC.  Question here is, if changing from one servo drive to another type, will the motion control code need to be updated to work with the new servo drive?  I have very limited experience with motion control itself at this stage so I'm a bit lost when it comes to these sort of details.
