HMS Communications Program.
This Program allows data transfer between a PC and HMS
controllers. The program and hardware allows communication
with up to 99 controllers. The controller's settings,
acquired data, alarm status may be viewed, logged and
changed from the PC. All acquired data may be graphed
and can also be displayed in real time. A database of
logged data is created. It can be managed, in that data
can be selectively deleted by specifying start and end
dates. A separate log is created for all alarm events.
The day's alarm events can be printed or displayed, or
start and end dates may be specified. Logged data may
be exported and imported into a spread sheet program.
The logging, polling intervals and baud rate can be set
