STRING_TO_IPADDR

This function converts a STRING in IP address format into a value of the data type 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 characters 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.

Permissible format:

'Octet1.Octet2.Octet3.Octet4[Space]', e.g.: ' [192.168.206.4] '

Permissible characters:

 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.

Decimal numbers "0"-"9", maximal 3 positions, with or without leading

zeros in the range 0-255
