Part II IEC Instructions
STRING_TO_IPADDR
_STEPSAVER
STRING (IP-Address Format 00a.0bb.0cc.ddd) to DWORD
The function uses for approx. 50 steps of generated code the basic instruction F76_A2BIN (see
page 637). The instruction expects that each octet consists of three cha
racters with leading zeros.
Otherwise the PLC delivers an operation error.
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.
Example:
Permissible format:
'Octet1.Octet2.Octet3.Octet4[Space]', e.g.: ' [192.168.206.4] '
Permissible characters:
Octets 1-4 Decimal numbers "0“-"9“, maximal 3 positions, with or without leading
zeros in the range 0-255

 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.
