Campbell Scientific PC400 Datalogger Support Software - Manual (Page 45)

Section 4. The PC400 Main Screen
On the left side of the LogTool window, is a display of all devices known to
PC400. You can choose to show all messages or filter them to show only
certain devices or dataloggers. PC400 will also store these messages to log files
on the PC’s hard drive and will eventually overwrite these files to keep them
from growing forever. You can control the number and size of each log file
type with the Options | Log File Settings menu and dialog.
PC400’s communications engine creates four different types of message logs.
Transaction messages are the highest level, and show every action undertaken
by PC400. For example, if you’re monitoring a datalogger every second,
PC400 will show clock check messages each second. Many of the messages
displayed on this log are understandable and may provide some insight to the
processes going on behind the scenes when you monitor or collect data.
The other three logs are more technical in nature, but can be very useful to
Campbell Scientific support engineers. Communications messages show when
devices are activated, the settings passed to those devices, and their responses.
This log may include “status”, “warning”, and “fault” messages. The Object
State messages record the state of each software object behind the scenes in
PC400. The most detailed log is the low level log. A separate log is stored for
each root level device (each COM port, IP port or TAPI port). These logs
record every byte sent or received through that port. Interpreting all of these
logs requires knowledge of both Campbell Scientific protocols as well as other,
lower level protocols, and requires detailed knowledge of what is supposed to
be happening. Most users will only need to access these logs when requested to
do so by Campbell Scientific support personnel.
For more information on these logs see Appendix C, Log Files and the
LogTool Application.
4.5.4.4 PakBus Graph
PakBus Graph is a utility that graphically depicts the connections in a PakBus
datalogger network. It provides a look at PC400’s PakBus routing table. In
addition, the utility can be used to change the settings of a PakBus device.
The window for PakBus graph is divided into three sections: the list of PakBus
devices, a graphical depiction of the PakBus network, and the log messages for
PakBus communication. The list of devices and the log can be toggled off by
clearing the Show List View and Show Log options, respectively.
Software servers are identified in PakBus Graph by the color green. Other
devices remain colorless unless they have been selected with the mouse cursor.
When selected, they are colored cyan.
The default PakBus address for PC400 is 4093. Other PakBus devices will be
shown by name and address, if known.
