Chapter 16 PLC Function ApplicationsC2000 Plus
16-166
16-13 Calendar function
The C2000 Plus's internal PLC includes calendar functions, but these may only be used when a
keypad (KPC-CC01) is connected, otherwise the function cannot be used. Currently-supported commands
include TCMP (comparison of calendar data), TZCP (calendar data range comparison), TADD (calendar
data addition), TSUB (calendar data subtraction), and TRD (calendar reading). Please refer to the
explanation of relevant commands and functions for the usage of these commands.
In real applications, the internal PLC can judge whether calendar function have been activated; if they
have been activated, calendar warning codes may be displayed in some situations. The basis for whether
a calendar function has been activated is whether the program has written the calendar time (D1063 to
D1069) in connection with the foregoing calendar commands or programs.
The calendar's time display is currently assigned to D1063 to D1069, and is defined as follows:

s to the commands TCMP, TZCP, TADD, or TSUB, if it is di
scovered that a

M1076 will be ON.

dar functions are operating, if the keypad is replaced with a
nother keypad,
it will jump to PLra.
2.

at the keypad has not been powered for more than 7 days, or
the time is wrong, PLra will be triggered.
