A4.3.3 Indicating Problem Severity and Status of Output
Module
The FA-M3 indicates the presence or absence of failures by the LEDs in the upper
section of the CPU module, classifying them into major, moderate and minor failures.
Tables A4.1 to A4.3 summarize the failure severity levels and the status of the output
module in each case.
See the Fiber-optic FA-bus Module and Fiber-optic FA-bus Type 2 Module, FA-bus Type
2 Module (IM 34M06H45-01E) for details on how the FAIL-signal contact output and
output module work if a failure arises in a transmission line, such as a fiber-optic cable,
in an application where a fiber-optic FA-bus type 2 module is in use.

*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).

*5: 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
