power or transient problems are ruled out, the CR800 probably needs an

operating-system update or repair

(p. 5) by Campbell Scientific.

10.5.4.8.2 Watchdoginfo.txt File

A WatchdogInfo.txt file is created on the CPU: drive when the CR800

experiences a software reset (as opposed to a hardware reset that increment the

WatchdogError field in the Status table). Postings of WatchdogInfo.txt files

are rare. Please consult with a Campbell Scientific support engineer at any

occurrence.

Debugging beyond identifying the source of the watchdog is quite involved.

Please contact a Campbell Scientific support engineer for assistance. Key things

to look for include the following:

• Are multiple tasks waiting for the same resource? This is always caused

by a software bug.

• In newer operating systems, there is information about the memory

regions. If anything like ColorX: fail is seen, this means that the

memory is corrupted.

• The comms memory information can also be a clue for PakBus and TCP

triggered watchdogs. For example, if COM1 is the source of the

watchdog, knowing exactly what is connected to the port and at what

baud rate and frequency (how often) the port is communicating are

valuable pieces of information.

10.6 Troubleshooting — Operating Systems

Updating the CR800 operating system will sometimes fix a problem. Operating

systems are available, free of charge, at www.campbellsci.com/downloads.

Operating systems undergo extensive testing prior to release by a professional

team of product testers. However, the function of any new component to a data

acquisition system should be thoroughly examined and tested by the integrator

and end user.
