Product Overview
The Schneider 172JNN21032 Serial Link Option Adapter is a compact communication interface component designed to support serial communication within industrial automation and control systems. With its compact dimensions and low weight, this adapter can be integrated into compatible Schneider automation architectures where reliable serial data exchange is required.
Serial communication remains important in many industrial installations, particularly in systems containing controllers, remote I/O devices, intelligent instruments, operator interfaces, drives, and other field-level equipment. The 172JNN21032 provides an interface between compatible automation equipment and serial communication networks, allowing operating data, status information, configuration parameters, and diagnostic information to be exchanged.
The adapter is particularly useful in automation installations where additional serial communication functionality is required without replacing the complete control system. Its compact design also makes it suitable for applications where cabinet space is limited.

Function and Working Principle
The main purpose of the Schneider 172JNN21032 Serial Link Option Adapter is to provide serial communication functionality within a compatible industrial automation system.
In an industrial control architecture, controllers need to exchange information with different types of equipment. Depending on the application, these devices may include remote I/O modules, intelligent field instruments, operator interfaces, motor drives, monitoring equipment, or other controllers.
The general communication path can be represented as:
Controller or Automation Device → 172JNN21032 Serial Link Adapter → Serial Communication Network → Connected Device
The adapter provides the communication interface required for data exchange between the automation system and compatible serial devices.
Typical information exchanged through an industrial serial communication system may include:
- Device status
- Process values
- Operating parameters
- Alarm information
- Diagnostic information
- Control commands
- Configuration data
- Maintenance information
The exact communication protocol and electrical interface depend on the Schneider automation platform and the equipment connected to the adapter. Therefore, the complete system configuration should be verified before installation or replacement.
Role in Industrial Control Systems
The 172JNN21032 can serve as an important communication accessory within an industrial automation architecture. Modern control systems often contain multiple levels, including controllers, field devices, monitoring equipment, and operator interfaces.
A serial communication adapter helps provide the connection between the control system and compatible serial devices, allowing information to move between different parts of the automation system.
The adapter may support communication involving:
- PLC and industrial controllers
- Remote automation devices
- Serial field devices
- Operator interfaces
- Intelligent instruments
- Industrial drives
- Monitoring systems
- Legacy automation equipment
This type of communication interface can be particularly valuable in existing automation systems where serial communication equipment remains in operation. Instead of replacing an entire control architecture, a suitable communication interface can help maintain communication with existing equipment.
Industrial Applications
The Schneider 172JNN21032 can be used in compatible industrial automation applications where serial communication is required between controllers and field-level equipment.
Factory Automation
Manufacturing systems often contain PLCs, drives, operator terminals, monitoring devices, and intelligent equipment that need to exchange operating information. Serial communication can provide a practical connection method for compatible devices.
Machine Control
Industrial machines may contain multiple control and monitoring components. The 172JNN21032 can help integrate compatible serial devices into the machine control architecture.
Process Automation
Process control systems can contain distributed instruments and automation equipment. Serial communication allows compatible devices to exchange measurements, status information, parameters, and diagnostic information.
Legacy Automation Systems
Serial interfaces remain common in older industrial equipment. The use of a suitable serial communication adapter can help extend the useful life of an existing automation system while reducing the need for a complete control-system replacement.
Industrial Monitoring
Serial communication can also be used to collect operating information from compatible devices for monitoring, maintenance, and diagnostic purposes.
Installation and System Integration
Correct installation is important for stable serial communication. Before installing the 172JNN21032, technicians should confirm that the adapter is designed for the target Schneider automation platform and that the required communication interface is supported.
1. Verify the System Configuration
Confirm the controller, rack, communication architecture, and designated option interface before installation.
2. Check the Product Identification
Verify the complete product number:
Schneider 172JNN21032
The model number should be compared with the original adapter and system documentation before replacement.
3. Install the Adapter
Install the adapter in its designated position and secure it correctly. Although the unit weighs only approximately 0.085 kg, correct mechanical installation is still important for reliable long-term operation.
4. Connect the Communication Cable
Connect the serial communication cable according to the applicable Schneider system configuration. Communication cables should be routed carefully and kept away from unnecessary sources of electromagnetic interference.
5. Configure Communication Parameters
Depending on the connected equipment, communication parameters such as addressing, transmission speed, data format, and other network settings may need to be configured.
6. Test Communication
After installation, communication should be tested before the system returns to normal production. Verify device recognition, stable data transmission, diagnostic information, and communication status.
