The following are some of our most FAQs for GE Fanuc Series 90-70 PLC
. Our GE Fanuc PLC specialists answer your top questions to provide helpful solutions.
What Software Is Available to Program and Troubleshoot the Series 90-70 PLC?
There are three different software packages to program and troubleshoot your 90-70 PLC. They include:
As the original software for 90-70 PLCs, this software can work with Windows 95, 98, and 2000. This program is not supported for Windows XP and Vista. Logicmaster 90-70 is considered a mature product by GE.
This software is compatible with Windows 95, 98, 2000, and XP, but not Windows Vista. VersaPro can also work with Series 90 Micros, 90-30s, and even VersaMax Micro and modular PLCs. This product is also considered mature by GE.
Proficy Machine Edition Logic Developer PLC
This is the only software that supports the new PACSystems and the present-day software for Series 90-70 PLCs. This software package is compatible with Windows 2000, XP, and Vista environments. PLCs that work with VersaPro Professional Edition software can work with the Proficy Machine Edition, including the RX3i and RX7i PACSystems. This software will continue to be upgraded as new systems become available.
When I Try to Download the Configuration to the Series 90 CPU, the Download Fails Because Passwords Are Disabled. How Can I Fix This?
If you try to download a configuration to a CPU that’s set to “Passwords Enabled” and the CPU that it’s actually being downloaded to is configured for “Passwords Disabled”, this error will display. In order to fix this error, you’ll need to completely erase the memory in the target CPU. Once passwords are disabled, the only way to download the “Passwords Enabled” configuration is to delete the memory.
To do this, you’ll need to:
- Power off your CPU
- Disconnect the battery
- Power on the CPU, but make sure the battery still disconnected
- Your memory should be erased
A second option would be to set the downloaded configuration settings to “Passwords Disabled” and then continue to download the configuration onto the intended CPU. This should only be done when losing passwords isn’t a problem.
My Series 90 CPU Stopped Working. What’s Going On?
First, check the LEDs on the power supply. Also check the LEDs on the CPU. The crucial ones to check are the POWER LED (which will tell you the health of the power supply) and the OK LED (which will tell you about the CPU health). If these look normal, then try one of the programming software packages acknowledged above (Logicmaster 90, VersaPro, or Proficy Machine Edition Logic Developer PLC) to link to the programming port and show the PLC and I/O fault tables. These will help find the cause of the failure. If your OK LED on the CPU is out, you’ll be incapable of communicating with the software.
After Assembling a Series 90-70 System, the OK LED on the CPU Is Off. After Switching the CPU, the Problem Still Exists. What’s Causing It?
The likely cause of this issue is that the CPU rack isn’t configured with the right rack number. The rack that holds your CPU should permanently be set to Rack 0. With any other setting, the OK LED will fail to come on. To check the settings, disconnect the power and remove the CPU from its rack. Look in the upper left of the rack, where numerous jumpers used to assign rack numbers are. Proceed with setting the number to 0.
Why Is My PC Not Connecting to the Programming Port on the Series 90 CPU?
There could be numerous things causing this problem.
- Bad Port on Your PC. You can use the PC’s serial port to connect to another device. This can help you see if it’s working correctly.
- Faulty Cable. Try connecting to another PLC to check the cable’s integrity.
- Inappropriate Communication Software Settings. The settings for the Series 90 CPU port are 19200 BAUD, 8 data bits, 1 stop bit, and odd parity. If the setting has been altered, look at the port configuration compared to the software’s port settings.
- Damaged Programming Port. Check the +5 volt pin (also called pin 5) on the programming port. If the +5 volts isn’t there, the fuse may be blown and this problem cannot be replaced in the field.
