Q1: What is the primary function of the 1747‑KFC15?
It is a DF1‑to‑ControlNet bridge. It allows an SLC 5/03, 5/04, or 5/05 processor (which only has a serial port) to communicate on a ControlNet network with HMIs, drives, and other devices. It connects to the SLC via the Channel 0 RS‑232 serial port, not through the backplane.
Q2: Can the 1747‑KFC15 control ControlNet distributed I/O modules?
No. The KFC15 is strictly an interface/messaging module for bridging serial data and programming terminals onto ControlNet. For I/O control, you must use the 1747‑SCNR scanner module in addition to the KFC15.
Q3: What is the Network Access Port (NAP) used for?
The NAP (8‑pin mini‑DIN) allows a programming terminal to connect directly to the ControlNet network without disrupting the physical coaxial wiring. This is a critical feature for troubleshooting and online programming without causing a plant‑wide communication fault.
Q4: Which SLC processors are compatible with the 1747‑KFC15?
The module is compatible with SLC 5/03, 5/04, and 5/05 processors. It connects to the processor via the Channel 0 RS‑232 port using a null‑modem cable (e.g., 1747‑CP3).
Q5: What configuration tools are required?
Configuration requires:
RSNetWorx for ControlNet – for scheduling the ControlNet network and defining Keeper attributes
RSLogix 500 – for configuring SLC Channel 0 parameters (Baud rate, parity, DF1 Full Duplex mode) to match the KFC15 DIP switch settings
RSLinx Classic – for PC communication setup using the "RS‑232 DF1 Devices" driver, selecting device type as "1770‑KF2/1785‑KE/1747‑KFC15".
The Allen-Bradley 1746-P1 is a rack-mount power supply for the SLC 500 programmable controller family. It accepts 120/240V AC input and provides 2A at 5V DC and 0.46A at 24V DC backplane power, along with a 200 mA user-power output for external sensors.
