Key ones to check are the POWER LED (which will indicate the health of your power supply) and the OK LED (which will indicate the health of your CPU). How do I identify the cause?Ĭheck the LEDs on your power supply as well as the CPU. You should only do this when passwords aren’t a problem. Once the memory is erased, a configuration with “Passwords Enabled” can be downloaded onto the CPU.Īlternatively, you could also change the configuration being downloaded to a “Passwords Disabled” setting and then download the configuration onto the CPU. This is done by removing the CPU from the baseplate and shorting across two solder pads labeled “MEM CLR” for about ten seconds. In some cases, you may have to clear the memory by shorting out a super-capacitor on the CPU module. You can do this by turning off the CPU, disconnecting the battery, and then turning the CPU back on with the battery still disconnected. When you disable passwords in a Series 90 CPU, there’s only one way to download a configuration where the CPU is configured for “Passwords Enabled,” and that is to completely erase the memory in the target CPU. When you try to download a configuration where the CPU is configured for “Passwords Enabled” and the CPU being downloaded is set for “Passwords Disabled,” you get this error.

When I try to download the configuration to my Series 90 CPU, the download fails because passwords are disabled.

While improvements to this software aren’t ongoing, this is the only software that will support new Series 90-30 and VersaMax CPUs and modules as they become available. This is the current software package for Series 90-30 PLCs and it supports all of the same PLCs that VersaPro Standard can as well as several of the newer Series 90-30 and VersaMax PLC that VersaPro Standard doesn’t. Another Windows-based package, it can run in Windows 2000, XP, and Vista. Proficy Machine Edition Logic Developer PLC Standard Edition.VersaPro Standard can program Series 90 Micros and even certain VersaMax Micro and modular PLCs. This Windows-based package can run in 95, 98, 2000, and XP environments, although like the Logicmaster, it’s not supported by GE Fanuc in the Windows Vista environment. As a mature product, no further improvements are planned. Please note that this software isn’t supported by GE Fanuc in Windows XP and Vista environments. As the original software for the Series 90-30 PLC, it’s DOS-based for your convenience to run in Windows 95, 98, and 2000. You have the choice of three different software packages for troubleshooting your GE 90-30. What software is available to program and troubleshoot GE Series 90-30 PLCs?
