5 I/O signal to CPU module
(10) Integrated value set completion flag (XnC)
(a) When Integrated value set request (YnC) is turned ON, and preset of each integrated
value such as electric energy (consumption), electric energy (regeneration), reactive
energy (consumption delay) is completed, this signal (XnC) turns ON.
(b) When Integrated value set request (YnC) is turned OFF, this signal (XnC) turns OFF.
(11) Max./min. values clear completion flag (XnD)
(a) When Max./min. values clear request (YnD) is turned ON and the data of max./min. value
(maximum value, minimum value and their date and time of occurrence) are cleared, this
signal (XnD) turns ON.
(b) When Max./min. values clear request (YnD) is turned OFF, this signal (XnD) turns OFF.
(12) Error flag (XnF)
(a) If an outside-set-value error occurs, and if a hardware error occurs, this signal (XnF) turns
ON.
(b) The description of the occurred error can be checked with a latest error code (Un\G3000).
* For description of error codes, refer to section 9.1.
(c) If an outside-set-value error occurs, this signal (XnF) is turned OFF by setting a value
within the range again.
