Well, that's because USEC are *microseconds*, not milliseconds.
Try to use sec=0 usec=5000000 instead.

sorry I forgot a line from the code:
I also decreased the sec param to 1 because for me the remote host is
quite fast.
<?php
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, array("sec"=>1,
"usec"=>0));
socket_connect($socket, "81.182.13.109", "502");
$pdu = "";
$pdu .= chr(0x03).chr(floor(16000 / 256)).chr(16000 %
256).chr(floor(10 / 256)).chr(10 % 256);
$rand = mt_rand(1,65535); //generate random adu id
$adu = "";
$adu .= chr(floor($rand / 256)).chr($rand %
256).chr(0).chr(0).chr(floor(6 / 256)).chr(6 % 256).chr(1);
$data = $adu.$pdu;
socket_write($socket, $data, strlen($data));
$result = socket_read($socket, 512, PHP_BINARY_READ);
echo socket_strerror(socket_last_error());
socket_shutdown($socket, 2);
socket_close($socket);
?>

And if I set sec=0 usec=500000 (or 5 for a shorter timeout) it hangs,
meaning to me, that usec has no effect.

Actual: Script gives timeout error but it does not wait for 5 seconds
for the answer, as set in SO_RCVTIMEO.
Expeted: to wait max. 5 second for remote host to answer, but script
executes much faster. I tried to increase second to 500000 and then it
works ok.
