Appendix A
Running Diagnostics
What’s in This Appendix
This appendix contains instructions for running the PKTXD utility and KTx
diagnostics. The PKTXD utility reports the IRQ and the base memory
address (one for each channel) of a PKTx card. The KTx diagnostics check
PKTx’s network and host communications, interrupts, and memory access.
Important: The 1784-PKTS card will not run the dual-port tests, i.e., it
will attempt to run and fail.
When Do I Run KT x Diagnostics?
Run KTx diagnostics if:
• you just installed the PKTx card
• you want to test if you have set up the PKTx card correctly
• you are unable to communicate with the programmable controller
• the remote I/O scanner is unable to communicate with adapters
Troubleshooting the PKT x Card
If your PKTx card is not functioning properly, follow these steps:
1. Verify you have the correct driver for the card. Refer to page 1-1 for
more information.
2. Continue with the instructions in this chapter to run the diagnostics to
determine if there are any hardware failures.
3. If you receive any failures, print the log file.
