PC295W
PC295W software is a freeware utility provided by Campbell Scientific to
write programs for the DataView II.
PC295W first reads the data logger program, to generate the list of Public
Variables and to determine the scan rate of the data logger. Once this
information has been determined, the user is able to choose a public variable to
display, and can associate “Description” and “Units” strings with it to form a
“screen”. A group of screens forms a user program, and PC295W saves this
program to disk in a DV2 file.
The CD295 is a PakBus device, using PakBus communications to
retrieve data from the data logger. However, the CD295 does not
support PakBus encryption. When the CD295 is connected to a
data logger using PakBus encryption, the data logger program
must include an
EncryptExempt()
statement with the PakBus
address of the CD295. Note that doing so will introduce an
exemption rule to the data logger security rules.
By default, the first part of the filename is the same as the data logger program
from which it was generated. So, for example, if you opened station1.cr2 to
create the DataView II program,
PC295W
would save the program as
station1.dv2. This naming convention is strongly recommended, but not
mandatory.
