*1 : When "Stop" is detected in CPU operating status, no script file is executed.
*2 : How many times a momentary stop was detected can be confirmed by the C Controller module dedicated function
(CCPU_GetPowerStatus).
While the C Controller module is detecting "Main CPU error", "Momentary stop detection" (including detection count update) and
"Power OFF detection" are not performed.
Further, the module may not be started up when this error occurs.
"Not checked" can be set in "Error check" in Project view  "Parameter"  "CCPU Parameter"  <<RAS settings >>in Setting/
*3 :
monitoring tools for the C Controller module.
*4 : The CPU operation status for error detection can be changed to "Continue" in "Operation mode at the time of error" in Project view
 "Parameter"  "CCPU Parameter"  <<RAS settings >> in Setting/monitoring tools for the C Controller module.
*5 : The CPU operation status for error detection can be changed to "Continue" in "H/W error time CPU operation mode" in Project
view  "Parameter"  "CCPU Parameter"  <<I/O assignment settings>> in Setting/monitoring tools for the C Controller
module.
*6 : For error details, you may check information in special relays ( Page 478, Appendix 6), special registers ( Page 480,
Appendix 7).
*7 : Whether to stop the multiple CPU system or not when an error occurs in CPU No.2, No.3, or No.4 can be set in "Operation mode"
in Project view  "Parameter"  "CCPU Parameter"  <<Multiple CPU settings>> in Setting/monitoring tools for the C Controller
module.
