FieldPoint Error Messages
No response within timeout period
Lookout
Direct
received no response from a device within the Receive
timeout period. The FieldPoint object is able to use the COM port, but
when it polls the device, the device does not respond. If you have
daisy-chained several devices, you have introduced an inherent delay. You
may have to significantly increase Receive timeout (and Poll Rate) to
ensure Lookout
Direct
is allowing enough time to receive the expected
response. This increase has nothing to do with the processing capabilities
of Lookout
Direct
. Rather it is based solely on Data rate and the number of
devices on the chain. Also, verify your baud rate settings, cable
connections, power, configuration settings, COM port settings, and polling
addresses.
Module returning ?? checksum
This means that the frame sent from the PLC in response to the command
sent by LookoutDirect out returned
?? instead of a valid checksum. Check
FieldPoint configuration.
Message Garbled - Bad CRC
This means the checksum (
CRC in this case) failed in a frame received by
Lookout
Direct
. Check cabling or for two or more devices with the same
address.
Unexpected data response length
The frame received was of an unexpected length. Check the LookoutDirect
receive gap setting.
Error loading IAK configuration file
Lookout
Direct
was not able to successfully extract data from the
.IAK
configuration file. Try running the FieldPoint Explorer again and
reconfigure your hardware.
FP error: Power-up clear expected
A command other than power-up clear was attempted after power-up or
power failure. The command sent is ignored and normal operations should
resume.
