Part II IEC Instructions
STRING_TO_IPADDR
STRING to IP Address
Thereby the attached string is first converted to a value of the data type STRING[32]. Finally this is
converted to a value of the data type DWORD via a sub-programm of approx. 330 steps that is also
used in the functions STRING_TO_IPADDR and STRING_TO_ETLANADDR.
To add an enable input and enable output to the instruction, select [With EN/ENO] from the
"Instructions" pane (LD, FBD or IL editor). To reuse an instruction select "Recently used" from the
context menu or press <Ctrl>+<Shift>+<v> in the programming window.

Availability of STRING_TO_IPADDR (see page 1331)
The analysis ends with the first non-decimal number after the 4th octet
or in case of a format error.
If the format is wrong the result is 0.
The conversion is such that the first octet represents the lowest byte
of the IP address and the fourth octet the highest byte of the ET-LAN
address. The format corresponds to the standard format as used in
"Standard Socket Application Interfaces", for example.
