Operand Description Data Size
D Area of F10240 ~ F2047R in F area BIT
1) FSET
(1) Sets the bit between F10240~F2047F among the Special Relay Area F.
(2) Able to control the F area as shown below.
Flag Name Data Size Contact Point Function
_RTC_WR BIT F10240 Write the data in a RTC
_SCAN_WR BIT F10241 Initialize the Scan Value
_CHK_ANC_ERR BIT F10242 Request the Error of external device
_CHK_ANC_WAR BIT
F10243 Request the Warning of external device
_INIT_DONE BIT F10250 Complete the Innitializing task execution
_ANC_ERR[n] WORD F1026 Information of the Error of external device
_ANC_WAR[n] WORD F1027 Information of the Warning of external device
_MON_YEAR_DT WORD F1034 Data of the clock information (Month/Year)
_TIME_DAY_DT WORD F1035 Data of the clock information (Time/Day)
_SEC_MIN_DT WORD F1036 Data of the clock information (Second/Minute)
_HUND_WK_DT WORD F1037
Data of the clock information
(Hundred/Weekday)
2) Contact point function
(1) F10240: After moving the clock data which writes to each area in F1034~F1037 of clock information
data area. If F10240 bit is changed to On using the FSET instruction, RTC data of PLC is reflected in
clock data of F1034~F1037 area.
(2) F10241: Initializes the value of _SCAN_MAX, _SCAN_MIN, _SCAN_CUR.
(3) F10242: If this bit becomes set and the value in F1026 area is not 0, error will occur. If error occurs,
PLC operation status is changed to error status.
(4) F10243: If this bit becomes set and the value in F1027 is not 0, warning will occur. If warning occurs,
P.S.LED of CPU module and CHK LED turns on. If you want to remove the warning, write ‘0’ in F1027
and set the F10242 bit. Refer to XGB-CPU User’s Manual Chapter 12.9 about the F10242 and F10243
contact points more detail.
3) Program Example
(1) If contact point P00000 connected with external device is changed to On, Write ‘100’ in
F1027(_ANC_WAR) and Warning Flag becomes Set.
