A value outside the permissible range of 0 to 4 has been configured for the 'Input response time X' parameter, where 'X' denotes a specific input terminal. This error can also occur if the 'Input response time X' is set shorter than the calculated input dark test pulse output time, which is derived from 'Input dark test pulse OFF time' and 'Number of pulse output for input dark test'.
Click steps to track your progress.
Set the 'Input response time X' parameter within the valid range from 0 to 4 for the affected input terminal.
Ensure the 'Input response time X' is set to a longer time than the calculated 'Input dark test pulse output time'.
