6.2 Self-Diagnostics Function
Error detection invalidation setting
Turning on the target bit of SD49 (Error detection invalidation setting) disables detection of the corresponding continuation
error.
*1
(Page 834 Diagnostic information)
*1 When using the error detection invalidation setting, check the version of the CPU module used. ( Page 1008 Added and Enhanced
Functions)
The following operations are not disabled even when the detection of the applicable continuation error is disabled in this
setting.
• Storage in buffer memory (Un\G770 to Un\G792) ( MELSEC iQ-R Ethernet User's Manual (Application))
• Setting of the completion status of the built-in Ethernet function instruction ( MELSEC iQ-R Programming Manual (CPU
Module Instructions, Standard Functions/Function Blocks))
Data is not retained in SD49 during power failure. Therefore, register this setting again after turning off and on or resetting the
CPU module.

The following table lists errors for which the detection of the continuation error can be disabled.
