Operation at error detection
When an error is detected in a diagnostic of the input dark test, the error (input dark test error) state is applied. For details on
the error state, refer to the following.

• For the NZ2GFSS2-32D-S1, when an error is detected in the input dark test, output dark test, or output
read-back diagnostic, the minor error state is applied to the module. However, when multiple errors are
detected and all I/O points of the module are turned off, the moderate error state of "Self-diagnostic error" is
applied.
• For the NZ2GFSS2-8D-S1 or NZ2GFSS2-16DTE-S1, when an error occurs for all the input points due to
the input dark test error or double input discrepancy detection error and the input function cannot be
performed anymore, an error state of I/O data error (010BH) is applied. However, when a minor error of
double input discrepancy detection error occurs while "1: Use" is set for the parameter "Double input
discrepancy auto recovery setting", the input function may be recovered. Thus, an error of I/O data error
(error code 010BH) does not occur even though the error occurs for all the input points. When an error is
detected in the input dark test, the minor error state is applied to the module.
