Communication Protocols

Protocols Tailored to Your Application

Nearly every modern engineering system employs some sort of critical, digital communication protocol. OPAL-RT simulators emulate industry-standard communication protocols, enabling users to perform the most realistic real-time simulations possible. Consult our comprehensive list of supported protocols below to learn more!
