Implementation of the basic functionality of the Modbus TCP and UDP based protocol using PHP. Implementation of the basic functionality of the Modbus TCP and UDP based protocol using PHP.

For more see [http://code.google.com/p/phpmodbus/downloads/list documentation] or [http://code.google.com/p/phpmodbus/wiki/FAQ FAQ]. Use the `setTimeout($seconds)` and `setSocketTimeout($read_timeout_sec, $write_timeout_sec)` methods to adjust wait times.
Most of the code is (to some extent) commented and documented with PhpDoc. You should get useful tooltips in your IDE.
## GoogleCode legacy docs & downloads
This project was originally hosted on (now defunct) Google Code. It's still archived here:

Note:
* The PHP extension php_sockets.dll should be enabled (server php.ini file)
