Server Protects Automation System Data
MatrikonOPC has released the latest OPC Server for Modbus open data sharing, to simplify open data sharing with its HC900 line of hybrid controllers. With expanded communication options and streamlined interface, the MatrikonOPC Server for Modbus provides users with optimized workflow making that makes configuration and maintenance faster and more intuitive.
The new Modbus OPC server offers built-in, role-based security down to the per tag level, which enables the integrity of automation system data to be protected. Based on each user’s login, the server selectively grants or denies access to specific tags, providing only the right users with secure access to the right process data.
The unit’s granular control over data access is designed to help prevent accidental or intentional unauthorized OPC data access. Key features include redundant device communications; precise control over who can access what data via role-based security; and support for OPC alarms and events.
