Q2: How many Ethernet ports does it have?
A: It has two copper RJ45 Ethernet ports supporting 10/100 Mbps communication.
Q3: What communication protocols does it support?
A: It supports EtherNet/IP and TCP/IP communication.
Q4: How many network connections can it support?
A: It supports up to 128 TCP connections and up to 256 CIP connections.
Q5: Does the 1756-EN2TRK support Device Level Ring (DLR)?
A: Yes. Its dual-port embedded switch supports Device Level Ring topology and linear network configurations.
Q6: What is the difference between 1756-EN2TR and 1756-EN2TRK?
A: The 1756-EN2TRK is the conformally coated version, providing additional protection against environmental contaminants. The 1756-EN2TR is the standard uncoated version.
Q7: What are its power requirements?
A: It draws 1 A at 5.1 VDC and 3 mA at 24 VDC from the ControlLogix backplane. Its power dissipation is 5.1 W.
Q8: Is the 1756-EN2TRK suitable for harsh industrial environments?
A: Its conformal coating provides additional protection for electronic components in demanding industrial environments. However, it has an open-style enclosure and should be installed inside a suitable control cabinet.
