FUNCTIONS
: Detectable : Not detectable
* 1 "Not checked" can be set in "Error check" in <<System settings>> of C Controller setting utility.
* 2 How many times a momentary stop was detected can be confirmed by the QBF_ReadStatusEx
function.
While the C Controller module is detecting "Main CPU error", "Momentary stop detection"
(including detection count update) and "Power OFF detection" are not performed.
* 3 The CPU operation status for error detection can be changed to "Continue" in "Operation mode at
the time of error" in <<System settings>> of C Controller setting utility.
* 4 The CPU operation status for error detection can be changed to "Continue" in "H/W error time CPU
operation mode" in <<I/O assignment settings>> of C Controller setting utility.
* 5 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 <<Multiple CPU settings>> of C Controller setting utility.
