Hi Star_69,   There are more ways to do this. If you als have a Scada computer in your network connected to the PLC LAN it is very easy. Just install your programming software GW-Works etc. at this scada PC and use a remote program like teamviewer or remote administrator (Radmin) to take over the control from where ever you are in the world. Any other PC will do as well but a scada computer is 24/7 switched on and connected to the PLC's. It only needs acces to the internet. If you like to divide the local PLC network from the company network just install an extra network card in a free slot in your PC. One LAN is to the PLC's IP range and the other is for the internet connection on the factory IP range. An alternative is to use a remote service router. My favorite is eWon. It connects trough the internet and is not interferring with the LAN network in the factory at the location. Just google on 'eWon Cosy' and 'Talk to M' as keywords to find more details and a movieclip that explains everything.   Best regards, Theo V.

Hi HWT, I suggest that you check the knowledgebase of your Mitsubishi distributor for examples. Best regards, Theo V.

Hi Despree, In the 'Manuals and Tutorials' I've uploaded the hardware manual for A-series CPU. Chapter 10 (starting from page 104) gives all kinds of information and flowcharts to identify (and solve) CPU problems. Best regards, Theo V.

Hi Adam 123, In the download section in the right column of this page under: 'Manuals, Tutorials' I've uploaded some hardware manuals for the FX3 series PLC. I hope this helps you out a bit Best regards, Theo V.

Hi Star_69, Maybe it is possible to take out the SD-card from the HMI and put it directly in your PC card reader to see if the card is readable and if allready100% of it's card memory is used. Aldough SD cards can contain a lot of data, It could be that there is not enough space to write the data or was not formatted correctly. I have no experience with GT1450 SD-card use but with an other brand and we solved a simmilar problem by placing an extra button in a service menu to manually dump data to the SD card and refresh the internal memory of the HMI. (that worked for an Exor Etop507 panel). Best regards, Theo V.

Hi Vasa and Gambit, Thank you for the fast reply. @Vasa, Unfortunatly the error happend while I was not present at the location so the reset key is used and the power switched off and on by a collegue in an attempt to solve the problem so the information in D9008 is gone. The attempt worked out fine however I always want to know what was the reason of the CPU to go into error and try to solve and avoid this in the future. @Gambit, We are currently replacing all A1, A2 to Q-series and FX0/FX1 for FX3-series (no FX5 used yet) and Beijer E-Terminals to GOT touchpanels and we are at >60% of the equipment now worldwide but this is a long term proces (over 100 PLC's) so we have to keep the A-series alive for two or three more years. (it's all about the money...) I keep some of the old replaced parts as a spare as most of this is not available anymore. The Mitsubishi's have proven their reliability trough the years that's why we are replacing with the same brand and also convert the serial connections to industrial Ethernet to be ready for the future. Thanks again and best regards, Theo V.

Dear all, Last week I had an A1 PLC in error. I was wondering if there is a D-register that contents the error which caused the PLC to go down. Especially the D-register that keeps the information of previous errors because we had to power down the PLC to reset the problem. The problem did not happend again but i like to know how to deal with it when it does. I Know there are some D9000 registers to show internal errors like battery fail however I don't know if there is also a register that shows the last and second last error after power down. I hope someone has the answers to this. I'm looking forward to hear from you. Best regards, Theo V.

Hi RSWolf, There are several ways to set the PLC in run/stop. 1) By using the small flip switch under the cover. 2) By activating the RUN terminal (if applicable at your model) Connect V- to the RUN terminal. 3) by using special markers in your software. Option 3: M8035 is a forced RUN/STOP mode M8036 is a forced RUN mode by activating this special internal function inside the PLC program. M8037 ia a forced STOP mode by activating this special internal function inside the PLC program. M8037 resets the PLC RUN state if this was set by using M8035 and M8036 signals. Ergo, you can try to force M8035 or M8036 to 1 to activate the RUN status. I hope this is clear enough. I've never done this before myself however I knew this is possible in the FX family PLC's so I looked it up in the FX programming manual (in Dutch...) Mayby try some seaching with Google to have an Englisch version avalaible. (search key could be: PLC Mode M8030-M8039) Best regards, Theo V.

Hi Theripley, You can ask your Siemens guy if he uses an OPC server to connect the Mitsubishi PLC to the Siemens Scada software. I know there are some OPC servers that can connect different brands. We used software from Kepware.com in the past with succes to connect Mitsubishi A-series PLC to Wizcon 9.4 and to Reliance 4.0 Scada software. Best regards, Theo V.

Hi PLC Freak, If the import option in GX-Developer is grey there is an escape possible however you need the Medoc software and make a 'print to file' and save this on your harddrive. After that print to file operation it is possible to import the FXGP(DOS) option in GX-Developer. Remember that you have to print including namelist and ladder to have all the labels imported as well. Best regards, Theo V.

Hi Star69, In my earlier post I wrote that the software can be downloaded to the FX3s. I made a mistake with the PLC type, In your example it should be the FX0s however, I agree with Crossbow to go to the newer type. In this case a FX3s will do nicely. You can convert your old software in GXWorks2 by using the build in GX developer software. Best regards, Theo V.

Hi Star 69, If the PLC which have the troubles is a FX0 and not a FX0N type this should work without a problem. Just change the PLC type in the software and download the program from the computer to the FX3S. Best regards, Theo V.

Hi Ulik, Dit you try to verify first to see if there are differences in the program on your PC and the program inside the PLC? This should not give a list of errors. Afterwards you can back-up if you like however is there is a 100% match this is not needed to save again. If there is no 100% match and you make an upload to the PC all the new items are at least without labels (if you use a simple ladder program) If you have legal software you can register this at the mitsibishi portal and get updates for free for your GXWorks2. Good luck, Theo V.

Dear Dharmesh, I wonder why you like to replace this GOT panel with an other brand. GOT panels are from Mitsubishi and can communicate as no other panel to your A-series CPU. However, if you really like to replace this with an other brand you can check out brands like Beijer electronic (MAC series) or Pro-Face. Beste regards, Theo V.

Hi Junkyard Gary, I can recommend the Mitsubishi Q-series with built-in Ethernet port like Q03CPU as a good replacement. We are in the middle of that same process and the A-series have proven that this is a reliable brand for many years (over 15 years) There is also a catch! Before you plan to change note that the Q-series outputcards have sometimes just 1 common for all outputs. The A-series have most of the time at least two commons. Aldough the working of the outputs itself is the same still you have to keep in mind if a common is behind an emergencystop circuit all outputs of one card are off at the same time. If you have signal horns or pilot lights that have to warn your personell you need to keep these outputs alive in case of the emergency situation. Also the conversion of the software is not always 100%. you can do an automatic conversion in GX-Works2 but functions that are present in A-series are not always compatible with the Q-series. The programm shows special markers SM999 in the ladder diagram that means something like 'I don't know what to do with this instruction' so beware that you have to check for these tricks. As a HMI we are using Beijer MAC E-1000 series and are transferring to GT2000 touch screen HMI's from Mitsubishi. This new GT2000 line is very nice however the programming is very different and less friendly compared to the Beijer panels. If there is no need to change the HMI you can communicate also the old panel to the Q-series if there is an Ethernet connection available. It was a lot of work and a challange to make the first machine run but in the end we are glad we have choosen for Mitsubishi again. I Did not do this conversions myself, we hired a technician for it but I checked what he was doing along the project. I hope this was helpfull an succes with your challenge. Best regards, Theo V.

Hi 1101, 1) Check if you can connect directly to the MAC by typing the IP adress in your internet browser. http:\\192.168.1.1 to see if you have the terminal screen opening. (you can not operate the HMI from this option) 2) Check in E-Designer under 'network services' if the checkbox 'remote Acces' is set to active. Standard portsettings are 5900 for the viewer and 5800 for the webacces. Best regards, Theo V.

Hi Transistor, Keep in mind that your laptop network port must be in the same range as the PLC IP number. Best regards, Theo V.

Hi Sachincool, It looks like your devide that you named "station 41" can not communicate. Check in your software wich device is station 41 the HMI or the PLC to determine where the problem occours. Check the UTP cables and if you have a switch or HUB in between also this hardware. If station 41 is the PLC check the error register of the PLC with GX-Works2 to see if there is a hint. I'm not an expert on Ethernet yet so this is all I can think of for now. Good luck with testing. Best regards, Theo V.

Hi Medensat, I made a trial set up to test what happens if you enter a password into the GOT. I think it is not working as we expect because if you set a password you change the acces level of the set up and not the software application inside. In fact is the software that you have written the part you like to protect. This is only possible in the software GT designer 3. You can check out yourself in the GOT: At booting press the left uppercorner of the terminal screen. After a while the set up screen appears. Now select 'GOT SETUP --> 'OPERATION' --> 'SECURITY SETTING' --> SECURUTY LEVEL CHANGE'. Here you can set a password. I could not complete this operation because I don't know the format of the password. It keeps telling password error. To close the set up mode press the small [X] in the right upper corner until all screens are closed. If you set a password in the software and send it to the terminal you have to type the password each time you want to open the application file. Whitout the password it will not open the file in the computer. To set the password in the PC: Open the project you like to protect. Then follow the steps from the menubar under 'PROJECT --> SEURITY --> USER MANAGEMENT. In this section you can add a users, levels and paswords. Remember I warned you to be careful using paswords. Make sure you can remember it or your file can never ever be recovered! Best regards, Theo V. I hope this helps you any further. Check it out.

Hi Baefam, If the existing converter was 4-20mA I should go for the same signal again by using a Phoenix MCR-PT100-I (part nr: 2810353) This way you don't need to change anything inside the PLC program. Using milli Amps signals is always prefered above voltage because of less EMC problems what can cause deviations in the output signal reading especially if you have no shielded cable and long cables running trough the same ducts as the mains power lines. If you take the Phoenix type MCR-PT100-U you need to change the input wireing to the PLC analogue module and do some new programming to your PLC. I think that you end up with more troubles than you have now. Best regards, Theo V.

Hi Nguyen, Today I asked the trainer at Koning + Hartman, Mitsubishi distributor in Holland, about your problem. He had never seen a GOT-screen upside down before. He only knows the portrait and landscape setting in the GT designer 3 software. I'm sorry to disappoint you but we have no instant solution for this problem. I hope anyone else on this forum has a suggestion? Best regards, TheoV.
