OfBiz POS for Weighbridge
Hi
An existing customer of ours is looking to replace their Weighbridge
software.
I haven't used or implemented the OfBiz POS module before, but for this
customer it might be a good fit.
I'm wondering if anyone else has done this, and maybe like to assist
with this project.
There are two 60 ton Weighbridges on site.
Each Weighbridge has a PC in a local building with a RS232 connected
Rinstrum 5000 Digital Indicator box
http://www.a1weighing.com.au/5000.htm
that the Load Cells of the Weighbridge terminate into.
My thoughts are that the data stream from the Rinstrum 5000 Digital
Indicator would be displayed to the user in OfBiz.
There are obviously lots of other requirements, but the data from the
RS232 is the main requirement that I do not know how to display in
realtime on the OfBiz or OfBiz POS UI.
I have a Rinstrum 5000 Digital Indicator that I can use for software dev
purposes, with some resistors arranged to pretend to be a Loadcell.
Regards
Andrew Dent

You probably need a process that listens to the RS232 feed from the
Weighbridge and records data and events.
This process could have a web service that would allow OFBiz to
interrogate the process to get current status or recent events.
I would be most comfortable with a separate box to replace the Digital
Indicator with a real-time display and let the OFBiz server ask this
machine for what it needs.
- I am assuming that this process needs to be available even if OFBiz is
not running.
- The RS232 link has no protocol so it does not have any error recovery
if the listener is not able to capture the Weighbridge data so a
dedicated PC is going to make operations more comfortable than a link
to a server that IT may stop and start without regard to operations needs.
- a warm backup unit could be kept by operations to ensure that a
failure of the main box does not shut down operations for an extended
period.
You probably need to provide some more details about what data and
events are captured and what OFBiz needs to present.
- real-time vs history
- display vs reports
- actions triggered in OFBiz by events captured from the Weighbridge
You may also want to provide some details about your thoughts on
synchronization of permanent data vs real-time display.
- allowable lag for transferring event details
- what triggers bulk data transfer - does the listener push data to
OFBiz or does OFBiz ask for data.

Hi Ruth
Your idea to use the Chrome App platform looks interesting.
I didn't know Chrome could do that and I will keep it in mind.

Hi Andrew:
Something one of my clients and I have been looking at:
The Google Chrome App platform. Not sure if this would work with an
RS232 interface, but with a USB device it is possible to write Chrome
Apps (using Javascript) to control the device and transfer data. Once
Chrome has hold of the data, it seems like an HTTP/S post, storage in
cookies and/or saving the data to an OFBiz aware/attached disk - could
allow OFBiz access.
Perhaps too simplistic for your application.
If interested, here is a link that I found really informative:
https://trenvo.com/blog/2015/01/interacting-usb-hid-devices-web-apps/
Just a thought.
Best Regards,
Ruth Hoffman
