![]() Yes, but you should be aware that using this output will reduce the amount of current available on the 24VDC output that goes to the Series 90-30 modules via the baseplate. This port is for the Ethernet Station Manager only!Ĭan I use the external 24VDC output on the Series 90-30 power supply to power external devices? If your problem isn’t solved after checking all these things, call our technical support specialists at 1-86.Ĭan I program my Series 90-30 IC693 CPU364, CPU372, and CPU374 through the serial port on the CPU module? If the +5 volts is not present, the fuse for that port is blown. You can check the +5 volt pin (pin 5) on the programming port versus pin 7 (0 volts). In cases where you think the setting may be changed and you have a copy of the PLC configuration, compare the CPU’s port configuration to your software’s port settings. The default settings for the Series 90 CPU programming port are 19200 BAUD, 8 data bits, 1 stop bit, and odd parity. You can try connecting to another Series 90 PLC in order to confirm the condition of the cable. You can try to use the PC’s serial port to communicate to another device in order to confirm proper operation. There could be several causes of the problem. What are the possible causes of this problem? My PLC will not communicate to the programming port on my Series 90 CPU. Note that if the OK LED light is out, the software won’t be able to communicate. These will help you find the root cause of your problem. If both of these are fine, then use one of the available programming packages (the three software programs mentioned above) to connect to the Series 90 programming port and check the PLC and I/O fault tables. 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. ![]()
