• Fieldbus Interface Modules: These modules allow control modules to communicate with devices using specific fieldbus protocols, such as Profibus or FOUNDATION Fieldbus.
• Ethernet Modules: Ethernet modules enable control modules to communicate with other devices via Ethernet.
• Serial Communication Modules: These modules allow control modules to communicate with other devices via serial communication ports.
