New high-performance CPU for Nexto modular PLC


We are delighted to release the new BCS-NX3008 CPU for machine and process applications, delivering the performance, connectivity and versatility required for Industry 4.0. With advanced software and cyber security features, the BCS-NX3008 provides you with a complete solution for systems of different segments and complexities.


The preemptive and multi-tasking operating system of the new BCS-NX3008 CPU operates on a high-speed 64-bit ARM processor with 1 GHz clock, 3 times faster than previous line models. This allows the BCS-NX3008 to control more than 2,000 input and output points as well as process complex arithmetic calculations, advanced control functions and more than 1,000 PID loops in up to 2 milliseconds. To ensure the integrity of the application where it is applied, the Altus newest CPU features 1 MB of retentive data memory. This feature, seen in most advanced control equipment, prevents the loss of operation data due to unexpected shutdowns or communication failures between the bus and the CPU.

Availability and high performance

In addition to the highlights related to hardware upgrades, the BCS-NX3008 also features new software resources for security, connectivity and virtualization. One of these features is the embedded VPN, which creates a private and direct tunnel when connected to the CPU. This functionality enables you to access your business control network remotely and safely. The CPU also supports FTP connections, which enables the device to exchange data with a server that uses the same technology. This functionality allows remote access to the data packets generated by the controller, such as logs collected through a datalogger function. Another new feature available on the BCS-NX3008 is the embedded Linux platform. The resource, native in the CPU, makes it possible to virtualize applications such as Unix based software. The feature enhances the versatility and speed of the operation system, allowing the processing of multiple data within the CPU.
