Turn the power off, and remove the top unit. While charging unscrew the 4 corner screws. You should always start by having the power onto the unit to charge the unit. Note: When removing the screws and working in the unit, the capacitor that keeps the ram memory stored is good for 5 minutes. To access the components in the main unit of the PLC, remove the 4 screws on each corner of the PLC. Typically this error is due to a battery error. There will be a blinking error light to indicate the error. The non-Fatal error will still run your program. (Fuses) The program will not run during a fatal error.
They can also happen if there is a power failure. Fatal and Non-Fatal.įatal errors will happen when the program or parts of the program have been lost. There are two possible error types in the PLC. If so then your program is still intact.Įrrors on the CPU – Omron Troubleshooting Check your EPROM sockets to see if a chip has been placed in the unit. This will tell us the condition of the PLC.ĭIP switches will control items such as language and program transfer from EPROM to RAM. It’s important to pay attention to the indicators on the front of the unit. The above picture will show the components on the CPU base of each of the controllers. This is why we are discussing the unit and plans for upgrades. Power supplies on this unit are rated for twenty-five years before failure. The K series PLC has very rugged hardware. This manual includes the installation, instruction set, and troubleshooting of the C20 PLC. This manual will review the installation and troubleshooting techniques on this programmable controller.Ĭ20 Programmable Controller – Sysmac C-Series – User’s Manual Installation Guide – Sysmac C20K/C28K/C40K/C60K Programmable Controllers

This manual will go through the instruction set as well as how to program the unit using the handheld unit. Operation Manual – Sysmac C20K/C28K/C40K/C60K Programmable Controllers The C20 was also referred to as a ‘Flatpack’ PLC. This is because the ‘K’ series could use the C20 expansion modules. You will note that the C20 manual is also listed.

The following are the manuals for the ‘K’ series PLCs. Planning for the eventual fatal failure of the CPU will also be discussed. We will take a look at this Omron PLC and review some troubleshooting techniques. These Omron ‘K’ series PLCs were popular controllers and have been in installations for over 25 years. The Omron C20K, C28K, C40K, and C60K shoebox programmable logic controllers have been discontinued since March of 2002.
