3-2 Installing the KFC15 Module Electrostatic Damage ! ATTENTION: Electrostatic discharge can damage semiconductor devices inside the KFC15 module. To guard against electrostatic damage wear an approved wrist strap grounding device, or touch a grounded object to rid yourself of electrostatic charge before handling the products. Overview of the Installation Procedure 1.
Installing the KFC15 Module 3-3 6. Connect the KFC15 module to your SLC500 processor with the supplied RS-232 cable. RS-232 cable 30664-M 7. Apply power to your SLC500 chassis. Connecting a Device to the Network Access Port Use the isolated network access port to connect a transitory device, such as a programming device, to the KFC15 module. Cables You must use the Allen-Bradley Network Access cable (cat. no. 1786-CP). 1784-5.
3-4 Installing the KFC15 Module Connecting to the ControlNet Cable System To connect the KFC15 to the ControlNet cable system use an approved ControlNet tap. Refer to the ControlNet Cable System Planning and Installation Manual (pub. no. 1786-6.2.1) for complete instructions on connecting the tap to the cable system. ! ATTENTION: If the KFC15 module is connected to a cable system that does not support redundant media, the tap dropline should be connected to the BNC connector labeled channel A.
Chapter 4 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 communication card to communication between your PC and the ControlNet network.
4-2 Communicating with the KFC15 Module Setting the Correct Options To 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. 1747-5.
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 configure RSLinx for communications on the ControlNet network. 5. Within the Processor Node field, enter the 1747-KFC15 ControlNet network address displaying on the KFC15 module. If you are unsure, remember the network address is set by the rotary switches on the KFC15 module.
4-4 Communicating with the KFC15 Module 6. Select the Auto-Configure pushbutton to obtain the serial parameters. Once you have confirmed the communication settings 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 information on interpreting the display. If you are unsure, you can check the three DIP switch banks on the KFC15 module for the particular settings.
Chapter 5 Troubleshooting the KFC15 Module Use this chapter to interpret 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-color (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).
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 between the two defined states (or with OFF if only one state is defined). This only applies to a single LED viewed independently of the other. If both ControlNet LEDs are flashing, they flash together (in phase). railroad - both LEDs alternate between the two defined states at the same time.
Troubleshooting the KFC15 Module LED State Probable Cause Channel A or OFF B (viewed separately) SOLID GREEN STATUS Channel disabled or unused Channel good—data is being received and transmitted on this channel FLASHING Temporary errors or GREEN - OFF device is not on-line FLASHING RED - Bad network GREEN configuration FLASHING RED - Media fault or no other OFF nodes present on the network OFF No power is applied to the KFC15 module SOLID GREEN Normal operation—the module is OK FLASHING The KFC15 is n
5-4 Troubleshooting the KFC15 Module This number Indicates this fault 1 Processor Fault 2 Invalid Firmware 3 Firmware Checksum Fault RAM Fault 4 Meaning A hardware fault was detected in the processor. This is a major fault. Return the KFC15 for servicing. The Flash EPROM does not contain valid firmware. New firmware must be downloaded to the unit. A checksum error was detected in the main application code of the Flash EPROM.
