+# phpmodbus
+
+Implementation of the basic functionality of the Modbus TCP and UDP based protocol using PHP. 
+
+**NOTE: This is a fork to fix & update the library code.**
+
+> **What's new**
+> 
+> This fork adds a namespace and fixes issues encountered when porting to PHP 7
+
+
+## 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
+
+
+## Requirements
+
+ * The PHP extension php_sockets.dll should be enabled (server php.ini file)
+
+ 
+## Example
+
+```php
+use PHPModbus\ModbusMaster; 
+use PHPModbus\PhpType; 
+
+// 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 . "\n";
+    echo $e;
+    exit;
+}
+// Print data in string format
+echo PhpType::bytes2string($recData); 
+```
+
+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.
+
