I/O Module Error

Error

There are more than 8 I/O modules.

A CLICK PLC system can support up to 8 I/O modules. Remove any excessive I/O modules.

At least one I/O module was added to the CLICK PLC during operation.

Power off the CLICK PLC and check the connection of the I/O modules. Then power on the CLICK PLC again. If the problem remains, connect the CLICK software to the PLC and check the System Configuration. If there is any I/O module that is not shown in the System Configuration, replace it.

An I/O module has failed.

Connect the CLICK software to the CLICK PLC and check the system configuration. If there is any I/O module that is used in the PLC system but not shown in the System Configuration window, replace the I/O module.

SC21

System Config Error

Error

The current system configuration does not match the configuration saved in the project file.

Connect the CLICK software to the CLICK PLC and open the System Configuration window. Modify the current configuration of the CLICK PLC to match the configuration in the project file, or uncheck the ‘Start-up I/O Config Check’ option if you want to use the current configuration.

103

SC22

 I/O Config Error

Error

At least one I/O module was removed from the CLICK PLC during operation.

Power off the CLICK PLC and check the connection of the I/O modules. Then power on the CLICK PLC again. If the problem remains, connect the CLICK software to the PLC and check the System Configuration. If there is any I/O module that is not shown in the System Configuration, replace it.

The CPU module can not access one or more I/O modules.

SC27

Lost SRAM Data

Warning

The data in the SRAM was lost while the CLICK PLC was powered off.

The CLICK CPU module does not have a battery back-up, but it has a capacitor that will hold memory for a few days. The data in the SRAM is lost if the CLICK PLC is powered off for long enough for the capacitor to discharge. In this case, the CLICK PLC initializes the data in the SRAM automatically. Power cycle the CLICK PLC to clear this Warning.

202

SC28

Battery Low Voltage

Warning

Battery voltage is too low to retain data in the SRAM.

Replace the battery (ADC part #: D2-BAT-1).

Also, set the new battery installation date and the anticipated replacement date in the CLICK programming software if the Battery Replacement Notification option is selected.

(Pull-down menu: Setup > Battery Backup Setup)

203

SC29

Battery Replacement

Warning

The anticipated battery

replacement date has passed.

Replace the battery (ADC part #: D2-BAT-1).  Also, set the new battery installation date and the anticipated replacement date in the CLICK programming software.

(Pull-down menu: Setup > Battery Backup Setup)
