Feature Analysis

1.High Reliability

The CS1W-OD211 is manufactured using modern large-scale integrated circuit technology and rigorous production processes, with advanced anti-interference techniques employed in its internal circuitry, ensuring high reliability. Some PLCs with redundant CPUs have even longer mean time between failures (MTBF). From the perspective of external PLC circuitry, using PLCs to form control systems significantly reduces failure rates compared to relay-contactor systems of similar scale. In the event of a failure, alarm information can be promptly issued, providing fault self-diagnosis protection for circuits and equipment in the system beyond the PLC.

2.Efficient Space Utilization

By installing multiple basic I/O units onto the CPU device, the CS1W-OD211 achieves efficient space utilization. For example, installing 10 basic I/O units (each with 96 I/O points) onto the CPU device enables control of up to 960 I/O points. Additionally, by combining analog input and output units, up to 80 analog I/O points can be controlled, meeting the demands of complex industrial control systems.

3.Optimized Data Refresh Performance

With the aid of the DLNK instruction in the new CS1 series PLC, the CS1W-OD211 can achieve immediate I/O refreshing, enhancing the refresh responsiveness of CPU bus units. During instruction execution, processes specific to CPU bus units, such as data linking and DeviceNet remote I/O communication and allocated CIO area/DM area word processes, can be immediately refreshed, ensuring data real-time accuracy.

4.Flexible Communication Interfaces

The CS1W-OD211 is equipped with two serial communication ports, RS-232C and RS-422A/485, supporting various communication protocols such as no protocol, macro protocol, 1:1 data connection, and 1:N mode NT linking. The RS-232C port has a maximum rate of 19.2kbps and a maximum distance of 15m, while the RS-422A/485 port also has a maximum rate of 19.2kbps but can reach a maximum distance of 500m, meeting the communication needs of different industrial environments.

5.Easy Installation and Maintenance

The CS1W-OD211 adopts a backplane installation method with screw terminal connections, ensuring quick and straightforward installation. Additionally, the module features fault self-diagnosis capabilities, allowing maintenance personnel to quickly locate and resolve issues with timely alarm information.
