Hi Everyone,I have a customer that needs a CQM1H (CPU51) replaced. They purchased the processor new-old-stock from a source they found online. It arrived in the original packaging and had the safety label around the top of the unit, so it seems that it is as advertised and no need to suspect that it would have problems. I purchased secondhand, a power supply to attach to it and program it from the bench instead of in the machine. The customer also provided me with an SD card containing the project file(s) for the machine. I am able to load the project in CX-ONE (running on Win 7) just fine. My computer has a native serial port (COM1) and I built a programming cable to work with the DB9 peripheral port according to a diagram I found online.The processor powers up right away with the ERR/ALM continuously on. No other LEDs came on initially, and after a bit of playing around with communications settings, I finally landed the right protocol and my computer seemed to identify the processor correctly. I compiled the source and attempted a transfer to the PLC. I got some failed message (or maybe messages) at the end of the transfer. It did seem to send all of the binary code, it just ended with an error message that I unfortunately didn't write down or grab a screenshot.Anyway, what I have now is a PLC processor with the ERR/ALM LED on always, I've never seen it in RUN mode, and now after the programming attempt, I'm seeing the COMM LED strobing at about a .5sec frequency (with or without a cable attached to the peripheral port), AND I cannot get CX-Programmer to again acknowledge the processor anymore. I'd like to reset this back to the way it arrived to me, but can't figure out how to make that happen offline. The DIP switches don't seem to cause that effect. I should say also that the DIP switch settings are all OFF except 3 and 7.Any help is much appreciated!Thanks,John

Hi, I am working wih 251MESE and somachine 4.3 And I am developing an application and the user who is going to use it needs to donwload a graphic that appears on the webvis, with all the information that it contains, does anyone done this before? How? I need some tips. I have the webvisu up and running I need something like download button to be able to download the info. Thanks!

Hi, I will upload a program from PLC and Download that program to another PLC. Do I need to Compile the program before I download it to the other PLC? Software: Gx Developer. PLC: FX-2NC-32MT Communication Cable SC09 Note: My laptop has only usb port Thanks for your support

I'm trying to transfer an application file to a PanelView 1400e and I'm having some difficulty. We currently have 4 of these in operation on machinery and we acquired a spare that I'm trying to get ready. All use the same exact application. I tried using a memory card but none of the PanelViews recognize any of the cards I do have at the moment so that option is out (though at one time we did transfer the applications this way so we did have at least one card that worked in the past). I was able to extract the application file from one of the PVs via Transfer Utility 32 on Windows XP. I am unable to transfer it back to the spare PV. I am using a 9 for 9 straight through serial cable on COM1 of the laptop to the 9 pin DB connector on the back of the PV. I match settings between the PV and the TU32 (baud rate, parity, error). I put the PV on Transfer Application screen on the Serial tab. I open up TU32 and choose the application file (approximately 86kb in size). If I select memory partition 1 for the destination, I get a dialog that pops up telling me that partition 1 is full and it shows me the size and free space on both partition 1 and partition 2. The size for partition 2 matches what I see on the PV on the Terminal Information screen (approximately 2200kb in size and same is free). When I then select partition 2 for the destination and click OK, it asks if I want to format the destination. If I click NO, the transfer fails because "User did not format the destination". When I click Yes to format, the PV starts formatting partition 2 and the progress bar goes up to 100%, then a message comes up that the format is complete, waiting for application transfer. On the TU32 screen, the format progress goes up to 11% then hangs and eventually reports that the format failed. I've done this a number of times and it is always 11%. However, when I click OK and then go back to the main screen on TU32 and once again select to transfer, the PV screen goes into transfer mode with a progress bar as does the TU32. No progress is ever made and eventually I get the 4209 error. 4209 error means the TU32 and PV are not communicating, basically. But I'm confused as to why they initially do communicate but only get to a specific point each time before communications stop. Any ideas? EDIT: Once I get the 4209 error, I click OK, and go back to the main TU32 screen. If I immediately click to transfer again, the progress bar on the PV disappears and a message comes up saying File Download failed-Ready for Transfer. If I click to Transfer again, the progress bar reappears but still no progress and this process repeats. Thank you in advance for any help you can offer.

Hello, We have a FX3G connected to a FX3U-ENET-ADP inside a main cabinet. We are then using that master PLC to collect data from 2 other fx3g plcs in a node:node serial network. I was assigned a small project of pricing out some wireless adapters so we can upload/download to the two slave plcs. My question is, is it possible to upload/download programs to/from the slave plcs through the ENET adapter and serial network in the main plc? It would save us some money if possible. thanks.

Hi, when I download on PLC (R04), sometimes for example. TON timer's output .Q is automatically set to true even though input is false (also on .ET time is 4h ...??). Also, sometimes some bool variables are also set to true even though they are not set by any kind of logic. However, when I physical reset the PLC (power cycle), mentioned problems don't exist. Does it mean that software reset isn't working entirely correct and I need to reset physical PLC (power cycle) every time after I download on PLC? Regards Luka

What is the best way to get to the configure screen when the mer file is set to auto run on the hmi. I need to get this file out before this screen finally quits on me.

Hi! I'm trying to download program to an e1001 but get errormessage "Unable to connect to Panel". After erasing the applikationprogram in the panel everything works fine. I can connect and download the program. Anyone knows why I couldn't connect or if I could have done differently? Is there some kind of program lock? BR Asp

I have read that it is possible, in CXDesigner, to download the program from the computer onto a memory card, and then download from the memory card into the HMI terminal. Is a similar thing possible with CXProgrammer, and PLCs? It would be quite useful, for the purposes of updating the program on a customer PLC that is located overseas, when the customer does not own a laptop with CXProgrammer installed.

We have a couple Mitsubishi FX2c-96MT 's running a Laser engraver and one of them appears to have a faulty card or connections on the card. we picked up a couple spares one is a FX2C-96MT and the other is FX2c-96MT-ess. Is there really a difference between these? I see on the old PLC the middle card says ess on it already? we need to "harvest" the current plc program before swapping into the new unit. we picked up one of the cheapie pc connection kits which doesn't look like it is right and don't want to connect it and burn something out. IT has a rs232 on one end than a male 25-pin connector with a second cord that goes from female 25-pin to the mini-DIN connector. Neither of the FX2c-96MT plc's have a mini-din connection as i read online everywhere. there is a 25-pin connector on the top next to the FX2c-96MT label. is this the programming port? I would have assumed the programming port would either be the one covered up by the battery cover or the little one on the end with a 3/8 x 1" cover. I am assuming thae, with no instructions for much of anything. Thanks for all and any help in this matter t we should be able to use an older laptop running winXP for this? i downloaded GX developer and will install it on the xp laptop as soon as we are able to be sure of a cable that will be safe and not damage anything. If this cable we purchased will not work, could someone send a link for instructions to fabricate one? I see several in a gogle search, but they are all different and we want to make sure we do this safely as the program on the PLC is apparently NOT backed up anywhere, and the people who set it up years ago are long gon Paul
