Section 1. Setting Up the Network and Communicating with the Datalogger
PC208W, Version 3.3, Instruction Manual 1-15
communication for all serial ports is displayed and can occur concurrently, it
may be helpful to turn scheduling off for all other sites when troubleshooting a
particular site.
The Log I/O to Disk checkbox is used to enable logging to a file in PC208W's
working directory. The files are named IO$COM1.LOG for COM1,
IO$COM2.LOG for COM2, and so on for COM ports, and IO$SOCKE.LOG
for socket connections. A separate file is used for each COM port, but all
socket activity is contained in one log. These files use a hexadecimal format so
binary characters can be viewed.
Information is saved to the IO$COMX.log file until it reaches 1.2M. Once it
reaches 1.2M it is named IO1COMX.log and new information is saved in the
file IO$COMX.log. Up to ten log files are created (IO$COMX.log,
IO1COM1.log, IO2COM1.log…IO9COMX.log), and then the oldest file is
overwritten with the next new log file. This method of overwriting older log
files prevents disk space from being consumed by the files. Because log files
are saved for each communications port, if multiple COM ports are used log
files can consume a substantial amount of disk space.
1.4.3 COMM SWF Messages
Messages pertaining to datalogger communications can be displayed by
selecting the View Messages button. Warning and Fault messages are always
displayed and logged to disk in a file named SWF$.LOG. Status messages are
also displayed if you enable the Show Status Messages checkbox and are
logged if you enable the Log Status Msgs box
Information is saved to the SWF$.log file until it reaches 1.2M. Once it reaches
1.2M it is named SWF1.log and new information is saved in the file SWF$.log.
Up to three log files are created (SWF$.log, SWF1.log and SWF2.log), and
then the oldest file is overwritten with the next new log file. This method of
overwriting older log files prevents disk space from being consumed by the
files.
The first character of the message indicates the type of message

Status,
Warning, or Fault. The time the message occurred is given next. The format is
DD HH:MM:SS, where DD is the day of the month, HH is the hour, MM the
minutes, and SS the seconds. The name of the relevant device and actual
message follow the time.
1.4.4 Pause
When PC208W is first started, all scheduled data collection is paused for 15
seconds. The text for the box in the lower right corner of the status window
reads Startup Pause. After 15 seconds, the Pause Schedule box will be either
checked or unchecked, depending on its state when you last closed PC208W.
When Pause Schedule is enabled, the Next Call information for any devices
with scheduled data collection will be grayed out.
