+phpmodbus
+=========
+This project deals with an implementation of the basic functionality of the Modbus TCP and UDP based protocol using PHP.
+It's a copy of the releases from the project page over at [Google Code](https://code.google.com/p/phpmodbus/) with
+composer support added.
+
+Features
+--------
+
+* Modbus master
+    * FC1 - Read coils
+    * FC2 - Read input discretes
+    * FC3 - Read holding registers
+    * FC4 - Read holding input registers
+    * FC5 - Write single coil
+    * FC6 - Write single register
+    * FC15 - Write multiple coils
+    * FC16 - Write multiple registers
+    * FC23 - Read/Write multiple registers
+
+Example
+-------
+
+```php
+ // Modbus master UDP
+ $modbus = new ModbusMaster("192.168.1.1", "UDP");
+ // Read multiple registers
+ try {
+     $recData = $modbus->readMultipleRegisters(0, 12288, 5);
+ }
+ catch (Exception $e) {
+     // Print error information if any
+     echo $modbus;
+     echo $e;
+     exit;
+ }
+ // Print data in string format
+ echo PhpType::bytes2string($recData);
+```
