16-13 Calendar functions
The C2000-HS '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:

*When a program writes to the commands TCMP, TZCP, TADD, or TSUB, if it is discovered that a
value exceeds the reasonable range, M1026 will be 1.
*When the keypad display is PLra (RTC correction warning) or PLrt (RTC time out warning), M1076
will be ON.
*When M1036 is 1, the PLC will ignore the calendar warning.
