*1: The severity level of this error item can be set using the Error-time Action field under Operation Control of the
Configuration. Setting the field to "Stop" indicates a moderate failure whilst setting it to "Run" indicates a minor
failure. The default value is "Stop" (moderate failure).
*2: The severity level of this error item can be set using the Error-time Action field under Operation Control of the
Configuration. Setting the field to "Stop" indicates a moderate failure whilst setting it to "Run" indicates a minor
failure. The default value is "Run" (minor failure).
*3: Output relays (Y □□□□□ ) of the advanced modules.
*4: When supply voltage abnormality is detected, output modules behave differently depending on whether the standard
mode or immediate detection mode is selected. Behaviors during momentary power failure in each mode are as
