Hi Beafam, I agree with Kaare_T. What you also can do to check if the problem is inside the PLC or in the PT100 temp converter is to use a simulator and put 0-10Vdc to the input of the PLC card. If this signal is linear going up and down as you vary the voltage you know that the PT100 to DC converter went bad. (Mind the plus and minus at the input of the PLC while testing) If you don't have a simulator you cabn use a regulated power supply 0-10Vdc as well. Good luck, Theo V.

Hi Medensat, It is very clear described in the manual. If you check the help function in GT designer 3 you find the way to do this. I'm warning you that you have to write the password somewhere down in and keep in a safe place, once it is lost you have a problem that the software will never open anymore and there is no escape from that! There are two ways to set a password. In the GT designer3 software so you can not open the application file that you made without the password. And you can set a password directly into the GOT panel. This password is not in a back-up in the application file only present in the GOT memory. Best regards, Theo V.

Hi Theodor, Always welcome to ask more at this forum and hopefully add some answers to questions from other members as wel. Stay tuned and we can learn from each other. Best regards, Theo V.

Hi Nguyen, After the picture I know what you mean by reversed. Actually it is not reversed but upside-down. I know the screen can rotate 90 degrees to use it as a portrait screen so hopefully this is a minor problem. Tuesday August 26 I have a GOT panel training for the new GT2000 series at the Dutch Mitsubishi distributor. I will ask if they have an idea what to do to solve this problem. The alarm message is indeed because there is no PLC connected or the communication to the PLC is not proper set. Best regards, Theo V.

Hi Nguyen, It is probably a difficult question, because no one answers? Did you try to re-load the software from your PC to the HMI to correct this inverse screens? If that isn't working you know it is a setting in the HMI panel itself. In that case, check the set-up of your HMI. To enter the main menu: press simultanously the upper left and right corner of the screen. Now the main menu should appear. You can try either: 'Debug&self check' or 'GOT set-up' options. I hope this will help you any futher in solving the problem. Best regards, Theo V.

Hi dr. Seuss, About the first screenshot: In my opinion if you use the ALT instruction it changes at every PLC scan so in your program you need to collect the X003 and X004 first to a PLS M.. instruction (... can be any marker value) to set the ALT function to true use Mxx to ALTernate Y031. To change the state of Y031 again use the same X003 and X004 --> PLS M... and then use M.. to to reset the ALT instruction. In my example below I use M1. I hope this wil help you if the solution of Inntele doens't help you to clear the memory. Screenshot 2 is also for me un-explainable. |--|X003|------------------[PLS M1] | | |--|X004|-| | |--|M1|---------------------[ALT Y031] Best regards, Theo V.

Hi OKI-PC, The FX-WIN files (extention .COW etc.) can be imported directly to GX-Developer 8. This GX-Developer is part of GX-Works2. Just open GX-Developer, choose file->import and select the FXGP(WIN) option. Now you can browse to the folder where all your old files are located and select the application file. Now you select the button 'PARAM+PROG' and click OK. Your file will be opened in the new enviroment. Save your new file as a GX-Developer file. User the verify option to see if the program in your PC is equal to the PLC. To see labels and comments use the VIEW menu and select the options you want to see (if these were also available in the original files) I hope this helps you any futher. Best regards, Theo V.

Hello Medensat, With all due respect for your energy to learn all this by yourself it is in my opinion best to have a training from your local distributor first. There are also some documents on the internet available. Use your search engine to find these manuals. I bought in 2014 a startkit (introduction offer from Mitsubishi) with a FX3GE PLC and GT1455 panel including a software licence for IQ Works (includes GX-Works2 and GT-Designer 3) There was a manual with some programming examples to learn about the touchscreen communication set up and digital and analogue in- and output signals to read and set at the HMI. I had HMI experience with Beijer panels for many years but this is something different. My advise is to check at your local Mitsubishi dealer for a similair training to start with. It doesn't make you a super programmer however it teaches you the basics of the HMI set-up and how to make a button/light blinking etc. Best regards, Theo V.

Hi Theodor, Welcome to mr. PLC, My experience so far is that there is a lot of knowledge with the members and (almost) always an answer if you post a Mitsubishi PLC question. Gambit did converted an application for me as a test however the results were very poor. The MAC E1032 is a graphic and text terminal and all graphics are converted but text not. The most applications that we run are text based screens. Text based screens are not automatically converted so I ended with the new application that had all the settings, alarmlist and no screens. If your applications are based on graphic screens it might turn out well. Just give it a try. I'm not sure if the conversion tool is commercial available yet. Gambit had a beta version from his work that was not released at that time. Just sent him a personal message to check. August 25th I wil have a training on GT2308 panel at the distrubutor's office planned so I hope that afer that training there are less secrets in the GOT panels for me. I made a project in a GT1455 and in my opinion E-designer and MAC is easier to use than GT and GT designer 3 but we have to move on in the new technlogy. Best regards, Theo V.

Hi Ron_S, I agree with the Ethernet option and should go for a FX3GE PLC and a small DIN-Rail switch (Weidmuller/Wago etc). Max. distance 90mtrs from the switch to the PLC and HMI's. If you use E-terminals you can set the network parameters in E-Designer to your controller. However take in account that in NL the Beijer MAC E1000 series are end of life. Al least the textdisplay versions like E1032 are no longer available as new order (serviceparts delivery up to 7 years) So if you need to start with something new you should consider GOT touchscreen panels from Mitsubishi to be 'future proof' Please check your distibutor about chemical resistance and also touch operation wearing latex gloves because some panels do have a problem with that. (Aldough I always advise to take of the gloves first to keep the screen clean and free from chemical polution) And, if applicable in your enviroment, the ATEX regulations to avoid explosion hazard situations. Best regards, Theo V.

Axion20010, You can use the relay output from a PLC outputcard if the common is connected to the power supply 24Vdc (NOT MAINS POWER!!) of the frequency inverter. If you need simple control use the relay contacts and if you have more advanced idea's to control speeds etc. consider a serial connection from the PLC to the drive. Good luck! Theo V.

Hi JoraMartio, You need Mitsubishi Melsec GX-Developer software that is integrated as a part of GX-Works2 and a SC09 cable to connect to your computer. If your computer has no serial COM port you also need an USB to Serial converter to connect. Remember that an upload from your CPU only gives you a raw ladder without labels. Example: In your ladderdiagram after upload you will see X2, Y30, D100 however it doesn't say X2, stop button, Y30 Motor left, D100 temperature etc. So you need to figour it out which labels and attach it yourself. Best regards, Theo V.

Hi R. Bukov, Could it be that an other program running in the background on your computer occupies the COM1 serial port? for example: E-designer for your HMI panel or CodeSys? I checked the settings with 7bit/even parity/1 stopbit on a FX1N PLC and that works fine so I'm out of options. Best regards, Theo V.

Hi Bukov, First of all, my compliments for the way you show the problem with the screenshots. This is very helpfull. For FX PLC try to set your RS232 serial connection to 9600 BAUD, 7 bits, Even parity and 1 stop bit. You have the right cable SC09 to connect to a FX1s. Also check if you use a serial to USB converter if your communication is still on COM1. If you have no RS232 port on your computer you need an USB to serial converter and usually your COM port is an other number like COM3 or so. You can check this in your Windows controlpanel (hardware, COM and LPT ports) Best regards, Theo V.

Hi Ron, Thanks for this feedback. I like the idea of the wire less connection also as a galvanic separation. Best regards, Theo V.

Hi Martin, Could it be that your file was saved as a 'Workspace file format' instead of a 'Single file format' by the original designer of the software? I had a situation like that with one of our external developers. I could not open the application that he made because he saved it not as a Single file format. Best regards, Theo V.

Hi Ron_S, Do you already have some experience about the range (distance) between the bluetooth device and your laptop in an industrial enviroment? Just curious. Best regards, Theo V.

Sorry Ron_S, I think you are stuck in the MEDOC decade? LOL This software could indeed select a FX2 for a FX1 because FX1 was an unknown type. In GXWorks2 or GX developer you need to change the PLC type otherwise you can not communicate. I agree with Crossbow, get the right software and enjoy free updates. Subject closed. Best regards, Theo V.

Crossbow, My reply was too quick. I've read the topic and assume that YYT want to program a FX1s with the GX developer. That is functioning 100% I've done this many times. If you like to convert FX1s to FX3s it is also possible by the option 'PLC change' However if you program in FX1s and want to communicate this with the FX3s or the other way around it wil NOT communicate with the PLC. You have a error message that tells you the PLC type doesn't match. Sorry to all for my mistake :( Best regards, Theo V.

Hi YYT, I've checked the FX1s type in the software and it is working fine under GX-Works2 V1.98c and also in GX-developer V8.109P which is part of this GX Works2 suite. Just select the FXCPU and FX1s model if you start a new project. Good luck with it! Theo V.

Hi WKla, As an alternative fotr th EEPROM cassette you can try to use a secure service router to connnect to your PLC in the field trough the internet (VPN). If you set up an eWon 141 cosy router this has Mitsubishi drivers on-board that can run on the serial programming port of the FX3. If your FX3 has an Ethernet port it is even more simple to connect based on IP. You have to use a SC-09 (the red one) programming cable between the eWon and the PLC RS422 port or use a RJ45 UTP patch cable between the eWon and PLC. The software to make the virtual connection is freeware. Check out www.Talk2M.com to learn more. Actually you can make an extended programming cable trough the internet that passes almost any firewall in the factory and gives you all the functions you have as if you had it connected on the workbench. Upload, monitor and change the program at the other end of the world even start the machine but that can be very dangerous! Best regards, Theo V.

Hi Igorlathin, Good to hear that you have communication up and running now. I'm not sure for freeware OPC servers for a mitsubishi protocol. We did use Kepware in the past to connect A-series PLC from Mitsubishi to Wizcon and Reliance which is SCADA software. However this cost some license fee. Search the web for some solutions, there must be something to find. http://www.kepware.com Keep us posted if you find a good freeware OPC server for MIT PLC's. Best regards, Theo V.

Hi Igorlathin, Try to move H81 to D8120 by using the trigger M8002 (first scan flag) This refreshes your communication to the port every PLC scan. Remember that only CH1 is available for the internal 232-BD board. |--|M8002|-----[MOV H81 D8120]---| Best regards, Theo V.

Hi Wal, Check the download section of Mitsubishi (see link below) and use as a search keyword: FX3UC-HW-E In this hardware manual you find several wireing examples and all other connection stuff. Best regards, Theo V https://nl3a.mitsubishielectric.com/fa/nl/service/download

Hi Harry998, I think your HMI is ok but the timer value in your PLC program is not retentive. If your timer is fixed you can use a constant (T0-K100 for a 10 Seconds timer) If you use a D-word to enter the value of the timer this D register needs to be in the range that holds the value. If you change the timer D you also have to change the D in the HMI. Which D registers are retentive is depending of the used PLC type FX or A or Q-series. Check for the manual to see what is the range. Best regards, Theo V.
