+# phpmodbus
+
+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/
+
+> **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+**WARNING: Everything except the actual code in this repo may be broken and outdated.**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:
+ * 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
+require_once dirname(__FILE__) . '/Phpmodbus/ModbusMaster.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); 
+```
+
+For more see [http://code.google.com/p/phpmodbus/downloads/list documentation] or [http://code.google.com/p/phpmodbus/wiki/FAQ FAQ].
+
+Note: 
+ * The PHP extension php_sockets.dll should be enabled (server php.ini file)
