Real-time clock
The PLC is provided with a real-time clock that can be accessed in
the user program via functions from the “SysLibRTC library”. The
functions are described in the PDF file “SysLibRTC”. After the
software is installed, this file can be opened via <Programs l
Moeller Software l easy Soft CoDeSys l Documentation l
Automation Manuals>.
The clock can be read or set using the browser command “getrtc”
and “setrtc”. More information is provided in section “setrtc” on
page 50.
The clock is backed up for at least 72 hours in the event of a power
failure.
Programming interface for the PC
To connect the controller with a PC, use the cable EU4A-RJ45-
CAB1. The cable should be plugged into the programming
interface (RS232) of the controller. The interface is not electrically
isolated.
The interface is initialised with the following default parameters
when the PLC is started.
