  1. 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

  3. Crouzet Millenium 3

    Recently had to get a program out of a millenium 3 plc which I had programmed a few years ago but the cable would not connect.The only difference this time ,as my laptop no longer had a rs232 port,was the use of a USB to rs232 converter. Having trawled the web I managed to find the circuit of the interface cable below. It looks like the signal from the computer uses the negative going part of the pulses which aren't present on most usb to rs232 converters. Is this correct?

  10. Hi, I have an old TSX 47 30 that has an I / O fault (red led on) green led on run and plc stopped. I'm writing to see if you can help me to establish communication and achieve the download of the program. I do not have the communication cable or the PL7-3 software under OS 2. So far I have done searches on the schneider page, forums and all the links are lost or deactivated. I have read your answers in plc of the same series and I observe that a converter rs 232 to current loop is needed. In this case here in Venezuela it is difficult to get this converter, however I have observed the black box model 232 CL-E, CL050A and I think it can be useful. I also have an old toshiba laptop with windows xp with a native rs 232 port to avoid another converter and I could make the connection cable DB25-DB9 to the PLC. Now I would miss the procedure to make an OS / 2 bios and get the software or make a virtual machine in which case I require the appropriate software .. thanks for your help

  14. Hello all - Wanted to check in and get some ideas on how everyone else out there stays organized with the various connectors, cables, etc. Currently I have been using a decent sized laptop backpack (keeping my laptop in there, spare battery and charger) along with various cables, connectors, external drive, CDs, screwdriver sets, wire crimps/strippers, etc. Seems though as I've been getting into different projects, different PLCs and such that the 'inventory' has been growing. Just wanted to hear others thoughts. Also, if you could maybe throw out your NEED TO CARRY items I'd be interested in what everyone else has to say. Sorry if this has been posted before or somewhere else. Thanks,  Kyle
