Implementation of the basic functionality of the Modbus TCP and UDP based protocol using PHP.
This is a fork of the original project at https://code.google.com/p/phpmodbus/
**NOTE: This is a fork to fix & update the library code (and code alone). Notably, the tests are probably all broken.**
> **What's new**
>
> This fork adds a namespace and fixes issues encountered when porting to PHP 7
**WARNING: Everything except the actual code in this repo may be broken and outdated.**
Implemented features:
## Implemented features
* Modbus master
* FC1 - Read coils
* FC2 - Read input discretes
@@ -22,18 +22,24 @@ Implemented features:
* FC16 - Write multiple registers
* FC23 - Read/Write multiple registers
Example:
## Requirements
* The PHP extension php_sockets.dll should be enabled (server php.ini file)
## Example
```php
require_once dirname(__FILE__) . '/Phpmodbus/ModbusMaster.php';
use PHPModbus/ModbusMaster;
use PHPModbus/PhpType;
// Modbus master UDP
$modbus = new ModbusMaster("192.168.1.1", "UDP");

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.
