Frequently Asked Questions

How does the C30 controller integrate with existing GE PACSystems PLCs for hybrid automation architectures?

The C30 communicates seamlessly with GE RX3i and RX7i PACSystems controllers via Ethernet Global Data (EGD) protocol or standard Modbus TCP. This enables distributed control strategies where the C30 handles protection functions while PACSystems manages process automation, sharing real-time data without proprietary gateways.

What cybersecurity measures protect the C30 controller from network-based attacks in critical infrastructure?

The controller implements multiple security layers: role-based user authentication with password complexity enforcement, encrypted HTTPS/SSH communications, MAC address filtering, VLAN segmentation support, and comprehensive audit logging. Firmware is digitally signed to prevent unauthorized modifications, meeting NERC CIP-005 and IEC 62351 security standards.

Can the modular I/O configuration be expanded or modified after initial installation?

Yes, the C30's hot-swappable I/O modules allow field expansion without powering down the controller or interrupting protection functions. Simply insert additional F6W, H6W, M6W, or specialty modules into available slots and configure via software—ideal for phased project deployments or future capacity upgrades.

What programming tools are required for configuring protection logic and communication settings?

GE's EnerVista software suite provides the complete configuration environment, featuring graphical logic editors, protection setting calculators, and IEC 61850 system configurator tools.
