The FLX controller (Wago 880) memory allocation is as follows:
RAM Memory
The RAM memory is used to create variables not required for communication with the
interfaces but for internal processing. This memory is NOT stored and is set to 0 or false or
initial values on startup and/or reset.
CODE Memory
The IEC 61131-3 program is filed in the code memory. The code memory is a flash ROM.
Once the supply voltage is applied, the program is transmitted from the flash to the RAM
memory. After a successful start-up, the PFC (Programmable Fieldbus Controller) cycle
starts when the operating mode switch is turned to its upper position or by a start command
from WAGO-I/O-PRO CAA.
NOVRAM (Remanent Memory)
The remanent memory is non volatile memory, i.e. all values are retained following a volt-
age failure. The memory management is automatic.
The BACKUP/RESTORE function is performed using the file transfer protocol (FTP). The
file system is mapped to RAM disk. To permanently store the data of the RAM disk, the
information is additionally copied into the flash memory. The data is stored in the flash after
the file has been closed. Due to the storage process, access times during write cycles are
long.
To Restore FLX Controller (PLC) / Remote I/O Controller (PLC):
i
NOTE: If Ethernet option is installed, then plug into the Ethernet coupler outside the panel or a spare port
on the Ethernet switch. If Ethernet option is not installed, then unplug the Ethernet cable currently
plugged into the FLX Controller/PLC going to the operator interface and plug directly into the controller.
1
Connect to the FLX Controller/PLC (880) via Ethernet.

Once connected, open Internet Explorer and enter the following address:
ftp://10.1.61.1 For the Remote I/O Controller (PLC) enter 10.1.61.100 or the cus-
i
NOTE: If IP address has been customized or multiple FLX systems are used, then enter that IP address in
replacement of the 10.1.61.1
tomized address.
