EtherNet/IP Deterministic Networks and Firmware Flash Compatibility
The 1788-ENBT daughter card establishes full-duplex Ethernet connectivity for FlexLogix and DriveLogix systems, transmitting I/O control data across EtherNet/IP deterministic networks. Integrating onboard packet-filtering logic, the card preserves high backplane bus communication velocity while managing implicit I/O messaging and CIP explicit data transfers to host controllers. Onboard flash memory ensures firmware flash compatibility, enabling synchronized firmware updates with parent processor hardware to maintain network protocol alignment.
Frequently Asked Questions
Q: Can the 1788-ENBT daughter card be installed or removed while the host controller is powered?
A: No. The 1788-ENBT communicates via direct internal backplane connection inside the controller housing; power to the parent FlexLogix or DriveLogix processor must be switched off prior to insertion or removal.
Q: What network physical cabling is required for the 1788-ENBT interface?
A: The card features a standard RJ45 port designed for unshielded twisted-pair (UTP) Category 5 or Category 6 Ethernet cables connecting to standard industrial switches.
Field Installation Guidelines
Power down the parent FlexLogix or DriveLogix controller and disconnect all external power sources before opening the chassis cover.
Align the 1788-ENBT daughter card edge connector with the designated internal expansion slot on the controller board.
Press the card firmly until the retaining tabs seat completely to prevent vibration-induced connection faults.
Insert an unshielded twisted-pair Ethernet cable with a standard RJ45 connector into the front network port until the latch clicks.
Reassemble the controller housing, restore power, and configure the module IP address using standard Rockwell software utilities.
