Cygnus 2 Operating Manual
3.5.9 Datalog
When a Source Shutter closes, an end of deposit occurs, or following a Stop, a set
of data will be collected. The data gives the user a snap shot of the layer data as
the layer completed.
There are three ways this data can be managed:
1
USB Storage USB Datalog Format set to Page or Comma
The data can be sent to a user supplied USB memory device in a data log file.
The file is saved as "MMDDYYC#.IDL" or "DDMMYYC#.IDL" depending on the
Date Format chosen in the General screen Date/Time page, see
where "C#" is Material Number.The data is formatted depending on the setting
of the "USB Data log format". Page format, see
, will insert a
carriage return and a line feed at the end of each line of data. In Comma format,
see
, a comma separates each piece of data.
Datalogging the crystal frequency data is an optional subset of the datalog
string and is enabled by selecting Yes for Datalog Xtal Info on the Comm page
of the General screen.
The information will be saved under a filename on the USB storage device.
Datalog files saved to the USB storage device will be automatically named
using the date and Material number. The format of the filename is
MMDDYYC#.IDL or DDMMYYC#.IDL depending on the Date Format chosen
where C# is the Material number. If the USB storage device already contains a
file with the same filename as the new datalog information, the new datalog
information will be appended to the old file.
At each Source shutter close, the datalog information will be appended to the
file (when saved to USB).
2
General Comm RS-232 Protocol set to Dlog Comma or Dlog Page
The data can also be sent to the RS-232 port if the General parameter "RS-232
Protocol" is set to "Dlog Page" or "Dlog Comma". See
and
for format descriptions. The RS-232 port then becomes a "send
only" port. The port will supply the data log data and will not accept any
commands from a remote computer.
Datalogging the crystal frequency data is an optional subset of the datalog
string and is enabled by selecting Yes for Datalog Xtal Info on the Comm page
of the General screen.

SL16 # and SL17 # commands
The data log information is always available via Status command SL16 # (no
crystal history) or SL17 # (with crystal history) in the remote communications.
The data is returned in the standard remote communications packet as binary
words. For more information, see
section 9.4.29, Status Material, on page 9-38
