Real Time Clock (RTC)
All XControl modular PLCs feature a real-time clock that you can access in
the user program. Possible functions are:
• Display mode for hours (12/24 hour display),
• Reading and setting of the real-time clock.
A description of the functions can be found in the XSOFT-CODESYS-3 manu-
facturer documentation for the SysLibRTC.lib library.
In addition, you can set and read the real-time clock with the following PLC
shell commands respectively:
• setrtc (set the real-time clock),
• getrtc (query the real-time clock).
Even in the event of a power supply failure, the real-time clock will continue
to work for up to 10 days thanks to a memory backup capacitor.
Memory
Modular PLCs XControl: XC-104-…, XC-204-…, XC-303-… feature 128 MB of
program memory (flash), 512 MB of RAM, and 128 kB of memory for saving
non-volatile application data (NVRAM).
