Bedrock’s Secure Industrial Serial Communications

Bedrock Automation extended cyber security to serial communications with its SIOS.5 Serial I/O module for its Open Secure Automation (OSA) control system.

The SIOS.5 has five channels, each supported by an independent cyber secure 32-bit ARM processor. Each channel is software-defined for RS-232, RS-485 or RS-422 communications, extending the range of industrial edge devices that can be secured by users of the Bedrock OSA.

“We connect every signal type to the Bedrock controller as software-defined I/O, with intrinsic cyber security,” said Albert Rooyakkers, Bedrock CTO and engineering vice president. “The SIOS.5 I/O module provides users tight and effortless serial data integration. Extending Bedrock intrinsic cyber to serial communications delivers authentication of the firmware and drivers. The SIOS.5 will be valuable for users and necessary for building a secure IIoT.”

Extending cyber security to serial communications results in improved reliability on a range of applications:
• RS-232 support enables secure communication with modems, gateways, printers, barcode readers, programmable devices and PC peripherals
• RS-422 support with a single bus master for process automation (chemicals, brewing, paper mills), factory automation (autos, metal fabrication), HVAC, security, motor control, and motion control
• RS-485 support for multi master bus/drivers
• Mainstream protocols such as Modbus and ProfiBusDP

Each of the SIOS.5 channels is independently configurable to support independent concurrent drivers. Five independent 32 bit ARM processors enable real-time performance of communications and control.

The Bedrock SIOS.5 Serial Bus module is available immediately.
