Profinet / EtherNet-IP Deterministic Networks and I/O Density Scaling
The 1797-ACNR15 uses ControlNet deterministic communication architecture with dual coaxial media ports for redundant network operation. The adapter manages communication between hazardous-location Flex Ex I/O modules and the ControlNet network while maintaining an I/O capacity of up to eight connected modules.
The module supports Flex Ex I/O density scaling through the 1797 platform architecture. ControlNet communication operates at 5 Mbps, providing scheduled and unscheduled data transfer functions for distributed industrial control applications.
Frequently Asked Questions
Q: Does the 1797-ACNR15 support redundant communication media?
A: Yes. The adapter provides two ControlNet BNC coaxial ports supporting redundant ControlNet media connections.
Q: How many Flex Ex I/O modules can be connected to the adapter?
A: The module supports connection of up to eight Flex Ex I/O modules within the Flex Ex I/O system.
Q: What mounting method is required for installation?
A: The 1797-ACNR15 is designed for DIN rail mounting. Installation requires proper grounding, shield termination, and separation of communication wiring from high-energy conductors.
Field Installation Guidelines
Install the 1797-ACNR15 on an appropriate DIN rail assembly with sufficient mechanical support. Verify that the hazardous-area installation complies with the specified intrinsic safety requirements before connecting field wiring.
Use the specified ControlNet coaxial cable types and maintain correct shield termination practices to reduce electromagnetic interference. Route communication cables separately from power conductors and avoid parallel runs with high-current wiring.
Confirm the supply voltage wiring polarity before energizing the module. Inspect LED indicators after startup to verify communication status, module status, and power conditions.
