# 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.
