XT wide temperature version (suffix XT): such as 1756-EN2TXT, 1756-DHRIOXT, working temperature -25~70 ℃, in compliance with ANSI/ISA-S71.04 G1/G2/G3, suitable for extreme industrial environments.
2. Legacy module (discontinued)
1756-EWEB: discontinued in November 2021, alternative solution is 1756-CMS1B1/CMS1C1 (Compute module);
1756-TIME: discontinued in November 2021, replaced by Aparian A-TSM/B time synchronization module( https://www.aparian.com/products/timesync ).
Common technical requirements and supporting resources
1. General parameters
Power supply and power consumption: Most modules rely on ControlLogix chassis 5.1V DC power supply, with a power consumption of 3.5~6.7W, and some require 24V DC assistance;
Installation requirements: 1 slot width, suitable for chassis such as 1756-A4/A7/A10, recommended power supply 1756-PA75/PB75 (regular), 1756-PAXT/PBXT (XT wide temperature version);
Electromagnetic compatibility (EMC): compliant with IEC 61000-6-2/-4, resistant to radiated interference (10V/m, 80-2000MHz), and resistant to EFT (± 3kV, 5kHz).
2. Key attachments
Network Type Attachment Model Description
EtherNet/IP 1585J-M8PBJM-x Ethernet jumper (2/5/10m, Cat5e/Cat6)
DeviceNet KwikLink Lite flat cable and IDC connector, fast networking without wire stripping
ControlNet 1786-RG6 quad shielded coaxial cable, 1786-TCT2BD1 (IP67 T-connector)
DH+1770-CD Belden 9463 dual axis cable, 9300-RADKIT (remote dialing kit)
Selection and migration suggestions
Priority for new projects: prioritize the selection of EtherNet/IP modules (1756-EN4TR/EN2TR), which support redundancy, encryption, and motion control, and are compatible with future expansion;
Legacy network maintenance: DH+/ControlNet module is only used for upgrading existing systems. It is recommended to migrate to EtherNet/IP for new scenarios;
Special environment adaptation: Choose the "K" coating for humid/corrosive environments, and the "XT" wide temperature version for high and low temperature environments to ensure compliance with on-site protection levels;
Module replacement for elimination: 1756-EWEB/1756-TIME needs to be replaced according to the recommended document plan to avoid operational risks in the later stage.
