6.2  Examples of Errors for CC-Link Embedded I/O Adapter 

This section explains examples of errors that occur in the input circuit, and the 
appropriate corrective actions. 

 

6.2.1  Errors occurring in the input circuit and corrective actions 

Examples of errors that occur in the input circuit and corrective actions are explained 
below:  

 

 

Error status 

Cause 

Corrective action 

Example 1  Input signals do not turn off. 

  Activation via the LED display switch. 

 

Leakage current

CC-Link

  A calculation example used to obtain the 

resistance value to be connected is shown 
on the following page. 

Example 2  Input signals do not turn off. 

  Sneak path due to the use of two power 

supplies.
