When windows came out you could use the Omron programming package called Syswin.
#Omron cx programmer counter error software
(Ladder Support Software) This was DOS based and programs saved with this software used the extension. The software that originally came out to communicate this way was LSS. Using a 3G2C7-LK201-EV1 (Host Link) unit which plugs into the peripheral connector you can communicate to a computer. You can still get these units off of ebay or other locations: I also demonstrate the use of this handheld in the video below.

You can see the entire operation of the handheld in the operation manual listed above. Your unit will display the error in the CPU. (This will ensure that the CPU continues running if we have a non-fatal error.) Press CLR, MON, CLR. Ensure that the switch is in either Run or Monitor mode. To view any alarms on the controller, plug the handheld unit into the CPU. A selector switch on the unit allowed you to select between Run, Monitor, and Program. This was one of the most popular methods to program the controller. A maximum of 10 16-bit registers could be used for each CPU unit for the expansion I/O units added.Ĭ28K-CDR-A (CPU 16 DC inputs / 12 relay outputs) + C20P-EDR-A (Expansion 12 DC inputs / 8 relay outputs)Ĭhannel 0 – Address 000.00 to 000.15 – 16 DC inputs CPUĬhannel 1 – Address 001.00 to 001.11 – 12 Relay outputs CPUĬhannel 2 – Address 002.00 to 002.11 – 12 DC inputs ExpansionĬhannel 3 – Address 003.00 to 003.07 – 8 Relay outputs ExpansionģG2C7-PRO15-E was the handheld unit that attaches to the peripheral connector on the CPU unit.

The K series PLCs used a fixed address system. This allows you to change the relay without bending the pins. Note: A relay puller was also included inside the unit to the right hand side. This way the individual relays could be changed without replacing the entire unit. Relay outputs on these controllers used sockets. You will have only 5 minutes to change this battery before you will lose the memory in the unit. The battery is in a holder and has a connector that will plug in. They are fuse holders and designed to be replaced when needed. One for the incoming supply and one for the 24VDC power supply. 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.
