  1. Alarm Display Customization

    You could also add Information to the alarm screen, which recipe was loaded when. For instance: "Recipe1 loaded" - or setup a logging, the logging could include the recipe number, that might help you also to track down the problem. Logging to be created on "trip". 
  2. Dear Forum, I am working on a set of "drivers" for some VFDs and wondering about you guys experience with it. The system layout is as following: FX5UC RS-485: MODBUS-RTU RS-485, lets say with 1x Mitsubishi F840, could be other drives (one drive per FX5UC) Ethernetport: Connected to GT2510, using Freqrol driver Another setup is for some other reasons not possible. I want to have one PLC program for different connected VFDs, scheduled VFDs at the moment are: Mitsubishi F-840, ABB ACS880, Toshiba L.V. VFD, Toshiba T-300MVi.   What I want to do: Read & Write status information - done. Read monitoring values - done. I want to setup some VFD parameters via the HMI. Send the parameter to the PLC and from the PLC to the VFD. The parameters are "basic VFD parameters", every VFD should have, such as: Torque boost, accel/decel time, min/max frequency, base voltage/frequency, etc. Of course these parameters are not simple Pr.0 to Pr. 125 but spread all over the place. I want to check for min. and max. limits inside the PLC before transmitting the data to the VFD. Knowing "basic parameters" will turn out quickly to "VFD specific parameters", I want to be prepared on the programming side. The APSRW for read/write parameters are called through the program and hand shakes with other APSRW calls.   What would be a good approach do to the above?  I rather invest more time into the PLC programming rather complicated HMI-Handling. Reading simple 125 words and the next 125 words, then writing 125word and again the next 125 words? Reading / writing individual parameters? Reading / writing 125 parameters at once? Any other approach for implementation?   Best regards, MarkusR  
  3. Inverter nameplate

    It is a small 2.3A VFD. FR-A840 is the Mitsubishi type. "FR" is simply a high class Mitsubishi VFD "A" means to my knowledge "Advanced" compared to the "F" version the "A" version has some special (motor) control functions. Whats your application? 840 means 400V type of the 800 series. 00023 mean 2.3A VFD output at SLD (Super Light Duty)
  4. FX5(UC) - MODBUS TCP/IP and RS-485

    Thanks Gambit, I just got reply from Mitsubishi that chainging baudrate etc. via user-program is not available anymore with FX5, it was available with FX3. Anyways, I am using GOT. It is good hint with multiple projects, thanks. Only problem I have is I am also logging to SD-Card, software update might get more complicated.
  5. GT Designer View used internal devices

    Mitsubishi has a very good manual - as much I like to be Independent - the online manual in the E-Manual Viewer is a very nice tool, also offline. See sector 12.1 for internal variables.   If you are referring to self created devices. You should use labels and properly group the labels and a naming scheme helps a lot.   Search/Replace => Device list => project.  
  6. Dear Forum, I am looking for a solution where I can select via the HMI which product is connected to the FX5UC PLC. EITHER Product A (Mitsubishi F840 via MODBUS TCP/IP) XOR Product B ( ABB ACS-880 via MODBUS TCP/IP) XOR Product C, XOR Product D, .... and/or EITHER Product C (MODBUS-RS-485 SLAVE) XOR Product D ( MODBUS-RS-485 SLAVE), XOR Product E....   The MODBUS TCP/IP registers for the products are different, (maybe) IP-Addresses are different. The MODBUS RS-485 RTU, the registers are different, the baud rate is different, the complete serial port configuration is different.   The setup which product is connect to the FX5UC is done once during commissioning.   I am wondering if the above is possible with the FX5UC. In the good old days I remember to open a serial port, define the baud rate, etc. within the ladder code. Process the data also in the ladder code, define the registers where to write the BUS-Data, etc. Looking on the FX5UC modbus manual, the definition of the slaves is done within the project, the data transfers are called automatically and not via the ladder code.   Can anybody answer if the above request can be done with the FX5UC? Can I configure / open / close the TCP/IP-Modbus and RS-485Modbus via the ladder program, rather than in the "project management" tool?   Best regards
  7. Dear forum, I am facing a trouble at the moment and hoping somebody can assist. I have one HMI software, GT Designer 3, HMI: GS2107 and/or GT2107, the software works so far so fine. The software is used on several products, I dont want to maintain two or even more software versions. Two serial devices are connect: 1x MODBUS RS-485 1x MODBUS RS-232. The data transfer is done via DDT, no direct calls. The DDT transfer the MODBUS address to the internal GD-Registers. The GD-Registers are used within the HMI. My trouble is that in some cases, there is no RS-232 device connected. This creates time outs, slows down the HMI and its just not nice looking (I have a warning implemented "WARNING NO CONNECTION TO SERIAL DEVICE RS-232". Is there a way, that I can select (retained) that the RS-232 is connected / or not? Once the software is configured "NO RS-232 CONNECTED" I can handle the rest of the software.   Anybody an idea how to do this? Many thanks.
  8. Mitsubishi FR-A800 Drive Problem

    Check your parameter 44 and 45 as well as your drive DIs and their assignment, maybe the second acceleration / dececeleration is active.
  9. How to lock out numerical inputs GT Designer 3

    There are several of doing it, If I understand you correctly you want to do following: 1. Log In 2. Enter the value 3. Lock out automatically. Concentrating on this and assuming, we are only talking about couple of numerical inputs, you could do following: Add a script to the numerical input, wich is activated after the new value is input. The script sets user level to 0. This script you can add to your "Operation - Data Operation - Write"  (USER LEVEL * K0) or you can use "EXTENDED - Write Device" and trigger a script. You are logged out.   Some other ways could be: - Add a log out button, the button sets user level to 0 - Add a log out routine, 5 minutes after log in and no page movement has been recognized, set user level to 0.   I would show the current user level in the header of your screen when you have some real estate you have sacrifice.
  10. password unlock tool

    Hi Rakesh. Good luck with this enquiry. Especially Mitsubishi is taking the locked PLC very seriously!  I have some expirience with the guys and the general rule is, if you don´t have the password, its not your software, we will not unlock it for you ( I am not even sure if they can).
  11. Conditionally display text field in GT designer3

    Hi salmonfish, texts are texts and cant be changed. You can use a "Simple Comment Display" or a "Bit comment" or a "Word comment" field.Depending on the application. The text can change in row and column (column by changing the language) Best regards
  12. LT_E Compare not working reliably

    Hi Technicus, at the first look the code looks good to me. I´m using the LT_E function quite often and never had a problem exuting it.   I would chase if your are wiring M_Druk_laag_veilig is double assigned or you are writing a word to it somewhere else in the program. Another option to try could be to use "LT" and AND the outpur with M8000. You can also check the compiler result, if, for whatever reason, the compiler gives you any stupid output. Try to observe your ENO output, if the function works properly.  
  13. stf and stop on at same time

    Could be PLC, could be wiring, could be VFD Setup. Hard to tell from these few Information. Basically what do you describe sounds to me like you trying to start the VFD but the VFD is somehow in stop. Some sort of interlock is active. Anyways, I would check MRS terminal and MRS configuration. Check Parameter 17 and Parameter 187. Also check if Parameter 19 (Base Voltage) is set.
  14. FTP to HMI (GS2107)

    I have the FTP Server on the GS2107 running and using it to download CSV files. I´m connecting via the Filezilla Client. Downloading and uploading works fine BUT it takes time and the connection might get disconnected, so filezilla is automatically reconnecting to the GS2107 and trying to perform the required action.   I used the GS2107 FTP function with Default Setting other than the timeout. This was set to the Minimum time which is 1 Minute if I remember correctly. I would try to use the filezilla if applicable. Set the filezilla to data type "binary".  
  15. GOT recipe record list.

    Veganic, I´ve been through issues with the recipe functions too. If you use the recipe functions as it comes with the GT Designer it should work quite fine. I would check your Settings, so you are refering to the right recipe. When you play with the recipe function I found it always very helpfull to delete the recipe files before updating the HMI. When you update the HMI Programm without deleting the recipe in advanced the "new" recipe file will not be updated by  GT Designer. The Import note here is the HMI Needs to have the "recipe Setup file". This is uploaded when no recipe file is on the HMI. If you Keep the recipe file it will not be updated and you will get funny results during Operation.
