KT card SI0 test timed out
KT card SI0 test failed with status code xx
The interface card failed the Serial Input Output test when it was first
powered on. You may need to restart, reseat, or replace the interface card.
KT card send mailbox timed out
The AB object timed out while waiting for the KT card to signal that it
is ready to be given a new message to send. This is most likely due to a
communication problem between the computer and the PLC. Confirm that
the network cable is properly installed and that the PLC is turned on.
NAK response received
The AB object received a NAK (not acknowledged) response when it
polled the device. The device received a command from Lookout
Direct
but
it did not accept the message. The command that the device received may
be incomplete or contain irregularities due to poor network performance. If
your Serial Port is configured for radio, you may need to adjust the RTS
delay off setting. Also consider increasing the number of Retry attempts.
No response — no ACK for our transmission
Lookout
Direct
is not getting any response from the device. This could be
caused by just about anything. Verify that the Data rate, Parity, and Error
detection settings are the same as the settings on the device. Make sure you
are using the proper Serial port on your computer. Verify that the device
interface module and other network equipment is connected and working
properly. If you are using a modem, verify that your object Phone number
and the serial port Dial-up settings are correct. This may also be caused by
low level noise or reflections on the highway, or marginal circuitry on
a card.
