EtherNet/IP and FLEX I/O Backplane Integration
The 1797-CEC provides the physical interface required for combining standard FLEX I/O modules and intrinsically safe FLEX Ex modules within a common I/O group. The module uses FlexBus connector architecture to maintain backplane communication paths while providing the required isolation boundary between module types.
The unit supports DIN rail installation and connects adapters or other FLEX I/O modules through integrated backplane connectors. The maximum supported configuration is eight I/O modules within the connected group.
Frequently Asked Questions
Q: Can the 1797-CEC be used to connect standard FLEX I/O modules with FLEX Ex modules?
A: Yes. The module is designed to connect standard FLEX I/O modules and intrinsically safe FLEX Ex modules within the same I/O group.
Q: What mounting method is required for the 1797-CEC?
A: The module is designed for DIN rail mounting in industrial control enclosures.
Q: Does the 1797-CEC include the required backplane connectors?
A: Yes. The module includes the master backplane connector and FLEX I/O backplane connector.
Field Installation Guidelines
Install the 1797-CEC on a properly secured DIN rail section and verify mechanical engagement of the FlexBus connectors before applying power. Maintain correct module orientation according to the FLEX I/O installation documentation.
Use appropriate industrial wiring practices, including separation between intrinsically safe field wiring and non-intrinsically safe circuits. Connect shielded communication or signal wiring according to the system grounding design and avoid routing signal cables parallel to high-current power conductors.
Before operation, confirm that connected FLEX I/O modules and adapters are compatible with the selected I/O group configuration. Inspect connector seating, enclosure protection, and terminal wiring integrity during commissioning.
