1769-L32E Built-in serial port flexible configuration

1769-L32E Built-in serial port flexible configuration
The 1769-L32E is a high-performance module in Rockwell Automation’s (Allen-Bradley) CompactLogix 5300 series controllers.
​It integrates powerful processing power, rich I/O interface and flexible communication function, and is widely used in various industrial automation control systems.
The built-in serial port is a major feature of the module, providing a convenient way to communicate with other devices in serial.
​Flexible configuration of built-in serial port
The 1769-L32E’s built-in serial port supports a variety of communication protocols and configuration options, giving users the flexibility to apply it to different communication scenarios.
​Communication protocol:
​DF1: A proprietary protocol used by Rockwell Automation to communicate with other Rockwell devices, such as the PanelView HMI, other CompactLogix controllers, etc.
Modbus RTU: A serial communication protocol widely used in industry to communicate with a wide range of Modbus-enabled devices.
Custom protocol: Users can customize communication protocols to meet specific application requirements.
Baud rate: Supports a variety of baud rates to suit different communication devices and environments.
​Data bits: Configurable data bits, such as 7 or 8 bits.
​Stop bit: You can configure a stop bit, such as 1 or 2 bits.
​Check bit: You can configure odd check, even check, or none check.
​Flow control: Hardware flow control or software flow control can be configured.

​Configuration method
The serial port of the 1769-L32E can be configured in the following ways:
​RSLogix 5000 Software:
In the RSLogix 5000 software, the serial port can be configured in detail through the TAB of controller properties, communication Settings, etc.
You can set the communication parameters, data format, and protocol type of the serial port.
ADDON instruction:
Using the ADDON command, the serial port parameters can be dynamically configured to achieve more flexible control.
