Product Features
Allen Bradley 1756-EN2TXT is -25°C to +70°C (-13°F to +158°F) and is much higher than common modules and is applicable to low-temperature or high-temperature industrial environments.
Allen Bradley 1756-EN2TXT as an EtherNet/IP network interface, it enables communication between the ControlLogix system and other EtherNet/IP devices, supporting real-time I/O data transmission and message exchange.
Allen Bradley 1756-EN2TXT supports industrial-grade security access control, enabling secure access to the control system from within the factory network.
Allen Bradley 1756-EN2TXT has obtained multiple environmental certifications (such as ANSI/ISA-S71.04-1985 Class G1/G2/G3), and is resistant to salt fog, corrosion, humidity, and fungal growth. It is also resistant to electromagnetic interference (EMI) and vibration/shock, making it suitable for complex industrial environments.
Product Working Principle
Allen Bradley 1756-EN2TXT is used primarily with controllers that are installed in the ControlLogix rack (like 1756-L8x/L7x) and which it serves by getting the controllers' commands through the backplane bus and transferring them to the external devices which have access to the Ethernet/IP interface.
Allen Bradley 1756-EN2TXT is based on the CIP protocol and supports two communication modes:
Implicit messages: real-time I/O data transmission (such as sensor and actuator signals).
Explicit messages: non-real-time configuration, diagnostic, or control commands (e.g., parameter modifications, status queries).
Allen Bradley 1756-EN2TXT features enhanced durability against wide temperature ranges and corrosive environments through special design elements (e.g., optional conformal coating), ensuring stable operation under harsh conditions.
