(2) Error storage
If any of the settings made in the buffer memory or the setting with the intelligent
function module is outside the setting range, the error occurrence (X8 to XF)
turns ON and the error code corresponding to the error definition is stored into
the buffer memory.
By checking the "error code" of the buffer memory, you can identify the error
cause.
