Configuring the KFC15 Module
Use this chapter to configur e the KFC15 communica tion parameters
via the DIP switches and rotary switches on the module.
Overview of Configuration Procedures
The KFC15 module is configured by using the DIP and rotary
switches located on the module. These two types of switches
configure the RS-232 seri al communic ation parameters, and the
network address. During configuration, the module must not be
powered. Once the switches are set, the module can then be i nstalled
in the SLC chassis. Located on the front of the KFC module is a dot
matrix display, which you can use to verify your settings. Refer to
Chapter 5 for more information on the dot matrix display.
Refer to Chapter 4 for information on configuring the communicat ion
between the SLC500 and the KFC15 modules.

Communicating with the KFC15 Module
This chapter explains how to use your 1747-KFC15 module to
communicate with your SLC500 processor.
RSLinx and RSLogix500
To use your KFC15 module to communicate with your SLC500
processor, you must have RSLinx and RSLogix500 installed on your
personal computer, along with an add-on module or communica tion
card to communication between your PC and the ControlNet networ k.
Examples of add-on modules for this type of configuration are the
1784-KTCX15, 1770-KFC15, and the 1784-PCC.

4-2 Communicating with the KFC15 Module
Setting the Correct Options
T o communicate with your SLC500 processor, using RSLogix500,
perform the following:
1. Start RSLogix500 and choose Comms from the menu.
2. Select System Comms from the pop-up menu. A dialog box is
displayed.

Communicating with the KFC15 Module 4-3
3. Select the System Communications tab.
4. From the Driver field, choose the appropriate driver for the add-on
module you are using from the drop-down list that was used to co nfigure
RSLinx for communications on the ControlNet network.
5. Within the Processor Node field, enter the 1747-KFC15 ControlNet
network address displa ying on the KFC15 module. If you are unsure,
remember the network address is se t by the rota ry switches on the
KFC15 mo dule. Refer t o Cha p te r 2 for more i n form at ion .
At this point you should be able to go on-line with your SLC500
processor.
Verifying the KFC and SLC Processor Communication Parameters
Both the SLC500 and the 1747-KFC15 RS-232 serial communication
parameters need to be identical for proper communication. The default
DIP switch settings for the KFC15 are the same defaul t settings used for
the SLC500. Only if you have changed the SLC500 se ttings do you need
to modify the settings for the KFC15. Below are the steps, perfor me d in
RSLinx, to verify the parameter s between the two modules.
Determine the Serial Parameters for the SLC Processor
1. Connect a serial cable from one of the communicat ion ports on your
computer to the SLC500 processor’s serial port.
2. Start RSLinx .
3. From the menu bar choose Communications, then Configure Drivers.
4. When the dialog box appears, choose RS232 DF1 Devices from the
Available Drivers list. Click on the Add New pushbutton.
5. When the di alog box appears , select SLC-CH0/Micr o/Panelview fr om
the Device Type list.
1747-5.34 - June 1998
4-4 Communicating with the KFC15 Module
6. Select the Auto-Configure pushbutton to obtain the serial parameters.
Once you have confirmed the communication se ttings for the SLC500,
you can use the dot matrix display on the KFC15 to verify the settings are
the same. Refer to Chapter 5 for infor mation on interpreting the display.
If you are unsure, you can check the three DIP switch banks on the
KFC15 module for the particular settings.

Troubleshooting the KFC15 Module
Use this chapter to interpr et the indicators (status LEDs and dot
matrix display) on the KFC15 module to help you troubleshoot
problems.
Interpreting the Status LEDs
There are three, bi-col or (red/green) status LEDs on the top of the
KFC15 module. Two are for ControlNet, showing the physical layer
status of channels A (primary connection) and B (redundant media
connection), and one is for the KFC15 (STATUS). These indicators
can help you diagnose problems with the modul e’s installation and
operation.

5-2 Troubleshooting the KFC15 Module
The following terms are used to describe the state of the LEDs:
solid - on continuously in the defined state
flashing - each LED alternates betwee n the two defined states (or with
OFF if only one state is defined). This only appl ies to a single LED
viewed independently of the other. If both ControlNet LEDs are flashing,
they flash together (in pha se).
railroad - both LEDs alter nate between the two de fined sta tes a t the same
time. This only applies to both ControlNet LEDs when viewed together.
The two LEDs are always in opposite states (out-of-phase).
flickering - intermittent on/off between the two states, often in an erra tic
pattern
