EtherNet/IP Deterministic Network Execution Layer
The 1747-L551/C implements Ethernet-based cyclic communication alongside legacy serial channels. Ethernet stack behavior is mapped to processor scan cycles, enabling synchronized data exchange with remote I/O adapters and supervisory nodes. Network determinism is dependent on scan execution timing and backplane scheduling of I/O updates.
Frequently Asked Questions
Q: Does the 1747-L551/C support hot-swapping in an active SLC chassis?
A: The CPU module does not support live insertion during system operation. Power cycle is required prior to replacement to avoid backplane bus interruption.
Q: What is the backplane load behavior during maximum I/O utilization?
A: Backplane current draw is distributed across chassis slots; CPU load remains fixed at approximately 4 W, while I/O modules define total system backplane consumption.
Q: Is firmware update via Ethernet supported on this CPU?
A: Firmware updates are executed through RSLogix 500 via Ethernet or serial connection. In-field flash operations require stable communication session and uninterrupted power.
Field Installation Guidelines
Install the module into an SLC 500 chassis slot with system power removed. Ensure backplane connectors are fully seated to maintain signal integrity across CPU and I/O modules. Ethernet cabling must follow standard twisted-pair shielding practices with proper grounding at cabinet entry only. RS-232 links require controlled cable length to minimize noise coupling. Maintain separation between communication wiring and high-voltage conductors according to industrial panel routing standards.
