I have a project that needs a continuous data acquisition, monitoring and storing solution to be build in LabView. It requires initially four simple RS232 and one RS485 driver to be written. There is some documentation available on the driver protocol but it may need work on figuring out the exact wiring and commands back and forth. I am using an industrial type RS232 to USB converter (FTDI chip) and two of the devices are able to talk to the computer. The other two I have not yet luck. This includes the RS485 and the issue maybe correct wiring as the instructions are skimpy (German). The devices are a motor, a temp controller, a Alicat mass flow meter and ph Electrodes. This is for a 6 bioreactor process control, monitoring and display application. In addition ideally I would like to add features such as a webcam and notification via email and a display on an iPad using the LabView iPad App. Data is to be stored in a text/csv/xls file. I have some samples and older versions (15 years old though) and have done similar work before. I am looking for a simple, easy to understand and elegant solutions with all the features that are necessary, yet not all what is possible. External devices include a motor, a temp controller, a Alicat mass flow meter and ph Electrodes. I would break the project into three stages: 1. RS Drivers and DAQ for simple display 2. Data display and storage per bioreactor 3. User Interface, messaging, integration of external data, visualization in iPad Let me know what your rough time estimate is for each step and what cost. Initial Budget is for the RS-232/485 driver only. I am using an industrial type RS232 to USB converter (FTDI chip) to pull the RS data into the computer. Two of the devices RS-232 devices are able to talk to the computer through the USB adapter. The other two I have not yet luck. The latter includes the RS485 and the issue maybe correct wiring as the instructions are skimpy (German). The devices are a motor, a temp controller, a Alicat mass flow meter and pH Electrodes via an amplifier. This is for a 6 bioreactor process control, monitoring and display application. There are 6 bioreactors, each of them has an Alicat massflow meter, a pH meter, a stirrer (RPM meter), and a heater with temperature probe. All signals come through RS-232 or RS-485 to the above mentioned USB Adapter. The 2 USB Adapter are connected to the laptop that runs LabView (2014 64bit). Initially it is required to write a VI/driver each for the massflow, pH, stirrer (RPM) and heater/temp, that will use the respective protocol (RS-232 or RS-485) to read and display all values and setting options, and make them available in LabView. To test and accept the VIs, however, VIs for all six reactors and all 4 parameters/RS inputs need to run in a simple test bench in parallel for all six reactors and acquire data and write to an excel file. Programming needs to be somewhat intelligent and minimizing the amount of code, i.e. recycle a VI just set different USB / RS port settings. I am open to suggestion on how to best / most effectively achieve this. Let me know what your rough time estimate is for each step and what cost. Initial Budget is for the RS-232/485 driver only. As I do have limited experience with RS-232 and RS-485 and the devices are in California, whereas you work remote, we may have to do trouble shooting on the cables and wiring. This implies that you are very familiar with the underlying electronics of RS-232 and RS-485 and how this would run through a USB converter into LabVIEW and how to write such driver, so you can guide trouble shooting. This is not for RS-232/485 beginner.

My name is Mateusz and I'm an experienced test automation specialist and LabVIEW programmer. I am Certified LabVIEW Architect since 2014. I've already sent you the same offer on the other platform, so I will just copy-paste it :) First of all, I would like to say that I am impressed by your offer content. It's well structured and written, includes many details. It's off the topic, but it's rare among customers and I really appreciate it! Surely I can help you with that, I have rich experience using LabVIEW, I have been also teaching others and certifying them as well. Writing drivers is not a problem, I've written RS drivers for tens of devices. Actually, I've also had Alicat (pressure controller) via RS232 and RS485, it worked well. The biggest challenge may be these devices that you cannot communicate with so far. Are they functional and working? I know RS232 and RS485 protocols, so it wouldn't be a problem to verify the connection. I would also like to see the documentation (even in German, I know basics) Of course, everything would be modular and reusable. That's my priority, I hate repeating my job, I prefer to do it once, make it universal and reliable, and reuse wherever possible :) I would gladly know more details about the whole project, it sounds like a good system for a nice visualization. What about preparing the data visualization panel as the interactive webpage, so you have access to it easily on any device? Feel free to text me, so we can discuss it.

Hi, I am an electronic engineer and CLD with 17 years experience with Labview in both scientific and industrial applications. I have written sofware to communicate with many devices using RS232 and RS485, eg, a Mettler Balance which it seems might be familiar to you? Each device always has it's own idiocyncracies. I recently completed a job here using the FTDI RS485 adaptor cable (see my reviews) so I am very familiar with the wiring requirements for the RS485 standard. Code re-use goes without saying, after all laziness is the first great virtue of a software developer. I would like to discuss this in more detail before commiting to times and costs per unit since this would depend on how much of the functionality you require for each unit, if you would be kind enough to message me. It would be ideal if you flew me to California of course, but I have no doubt that this can be done remotely :-)

Hello, I would like to express my interest in your project. I am a certified LabVIEW developer having over 6 years of experience in developing test, measurement and data acquisition solutions using LabVIEW and a variety of hardware and sensors for aerospace industry. I have extensive experience in interfacing devices to LabVIEW that's uses RS232/485/422 protocols and also in developing the serial drivers for these devices from scratch. Please visit my profile and the portfolio to know more about my skills and experience. Infact some of the projects displayed on the portfolio had multiple devices that uses RS232/485. I can complete the fist stage within two weeks (may be even lesser), but would like to know complete details first. Do you have any protocol manual for the device that could be shared.? Please let me know the model/make of each of these devices. I would be happy to demonstrate few of my work samples to you. I look forward to hearing from you. Best Regards Deepu Jacob

Hi there, I came across this job posting and found it very interesting. I’ve extensive experience with application development and instrument control (including driver development) using LabVIEW. I’m familiar with many popular design patterns including Queued State Machine, Event Based SM, Producer/Consumer, Actor Framework (OOP based) etc I’m also a Certified LabVIEW Architect (CLA). I can share link to the certificate. I’ve done numerous projects which required remote deployment and debugging. Kindly let me know if you’re considering candidates outside USA as well, as I’m based out of Toronto, Canada. Kind regards Ashwani
