For C010H to C021H
Check item
Check whether the module parameters of the R60AD8-G are correct.
For C030H
Check item
Check whether the correct SIL2 safety program FB is used.
Corrective action
Check that the standard/safety shared labels used in the SIL2 safety program
FB and the SIL2 standard program FB match.
Check that "SIL2 A/D conversion cycle setting" is within the setting range.
Also check that the parameter satisfies the setting value calculation formula.
For details, refer to the following.

Page 277 "SIL2 A/D conversion cycle setting"
Turn on i_bEN (execution command) of the SIL2 standard program FB.
Corrective action
Check that the module parameters of the R60AD8-G indicated by status code
are set within the setting range and the setting values are correct.
Corrective action
Check that the SIL2 safety program FB (M+SIL2ADG_ADConv_R) has been
attached to the safety program. For details, refer to the following.
