Advantages Over Competing Modules
Compared to other Ethernet/IP modules in the ControlLogix family (e.g., 1756-EN2T), the 1756-EN2TR offers several key advantages:
Gigabit Ethernet Speed: The 1000 Mbps ports provide faster data transfer rates than the 10/100 Mbps ports of the 1756-EN2T, making it ideal for high-bandwidth applications.
Enhanced Security: Advanced security features (e.g., 802.1X, TLS) provide better protection against cyber threats compared to older modules.
Improved Redundancy: Tighter integration with ControlLogix redundancy systems ensures faster failover and higher availability for critical applications.
