Step by step instructions for setting up a Peer to Peer configuration for a WebDAQ.


You can setup a direct connection between a WebDAQ and a personal computer for data collection directly to the PC.
The WebDAQ has the ability to log data directly to a networked drive for storage and review.  General instructions for that are already available in the WebDAQ's help.
Logging directly to a Peer to Peer configuration is a variant of this.  Here is how to do it.

Given:
laptop/notebook running Windows 7, 32/64 bit (or Windows 10) with no other network connection (air gapped).
A WebDAQ316 with at least 1 channel configured for temperature (this example uses 8 channels). 
1 CAT5/CAT6 cable.

WebDAQ Channels are set up as:
T type TC, 
°F, 
Rate = 1Hz, 
Auto zero every sample, 
Immediate start, 
Manual stop, 
file name: Network Storage\qwerty\Job1,  (more on this step below*)
Append Date/Time to File Name,
No alarms.

Per the WebDAQ's user's manual, All WebDAQs use a default IP address of 169.254.100.100.
Therefore, you will need to set up your conputer's IP address to something on the same Gateway of 169.254.100.xxx.

For this example, configure the PC to an IPV4 address of:
IP address: 169.254.100.5
Subnet mask: 255.255.0.0
Default Gateway: 169.254.100.1

Create a new folder on PC from Documents: MyWebDAQdata.
After creation, Right click on the folder name, select Properties button.

From MyWebDAQdata dialog property page, uncheck attribute property “Read Only”
Click on the Sharing tab, click “Share” button.

File Sharing Dialog shows.  On my computer it shows 1 entry (on my computer): Jeff-ACER  Owner.

Drop down on downward pointing arrow head “\/”, select “Guest”,  and then click “Add”.
Change permission level to “Read/Write”, click “Share”
Folder now shows (on my computer):
MyWebDAQdata
\\JEFF-ACER-PC\Users\Jeff-ACER\Documents\MyWebDAQdata
Click “Done”.

Back to MyWebDAQdata Properties Dialog, click Advanced sharing button.
Advanced sharing dialog opens.
  1. Add check to “Share this folder", and User default share name, “MyWebDAQdata”.
  2. Click “Permissions” button.  Group or username: Everyone.
  3. Set permissions for Everyone to allow:
  4. Full control
  5. Change
  6. Read
  7. Click OK

Back to MyWebDAQdata Properties dialog.
Under Password protection, click the Link to, ”Network and Sharing Center”.
Confirm or set as follows:
  1. Turn on Network discovery
  2. Turn on file and printer sharing
  3. Turn on sharing so any with network access….
  4. Use 128 bit encryption…
  5. Turn off password protected sharing
  6. Click “Save Changes”

Close MyWebDAQdata properties.

if you have not done so already, connect the CAT5 cable between the computer and WebDAQ, and turn on the WebDAQ.

Once the WebDAQ completes power up cycle, open your PC’s browser, go to webpage by entering 169.254.100.100 in the address bar (default for any WebDAQ).
When the webpage opens, 
From the column on left, click 'Device', and then the 'Storage' tab.
Click the “Map Drive…” button.

When dialog box opens, select/Confirm radio button for "Network Folder."
and then fill in these parameters:
Address:  //169.254.100.5/MyWebDAQdata
Domain: Leave empty
Username:  Everyone
Password:  Leave empty

*Mount Point name:  qwerty 
Click “Apply”

Newly mapped drive should show up on the WebDAQ's Storage tab page.

Edit job:
Change Log file options:
Click Browse, to open the page.
Click Network Storage,
Click qwerty
Edit file name (I left it at “Job1”), click OK.

Back to Job Editor Dialog.
Note, there is a warning, “Logging directly to network may cause overruns”  (just be aware of this).

Lastly, run Schedule or Job.

Data will now be logged directly to the PC's Documents\MyWebDAQdata.

Notes:
You can use any WebDAQ, not just the '316.
You can use any supported OS, I happened to use Windows 7, 64 bit on a generic notebook (because I had one).
