Having returned back to the office, this week comprised of preparing and waiting for paper work and documents for another client project. One of the in-office engineers very graciously offered up their time to introduce us to more aspects of the DeltaV system and how to work further on writing code and developing graphics for operator stations.
This week I continued with following up on what changes or variations clients required on site.
The engineering colleagues I was working with then took me on a tour of the facility allowing me to see how all the various departments work together to develop a product and how the automation aspect fit in. I also got first hand glimpse in the production set up. A few weeks ago I was introduced to P&ID schematics and this week I got to relate the symbols to their physical equipment counterparts which I personally really appreciated as it clarified a lot in m mind.
This week I got to visit a client site and work with on-site engineers who are in different developmental stages of a project than stages I have been exposed to in the office.
I also got to learn more about other clients as there were 2 others involved in this project. The week was spent mostly getting set up, completing tasks and corresponding with the international clients.
This week involved again more document control and observations. The client had requested a name change for some of the parameters within the software and as a result all corresponding materials must be changed and corrected to align with their request.
The second half of this week will be visiting a client site for a separate project to aid with onsite documentation. I’m thoroughly looking forward to getting out to see what engineers on site get to do and also a change of scenery is always pleasant.
Quality control of documentation and aiding in the development of new documentation for a separate project is what I’ve been splitting my time between this week.
For the project I mentioned last week (XDR and Wave bioreactors) the factory acceptance testing is drawing to a close. As the engineers finalize the documents they make them available to me to which I review and compare it to the client document ensure they match. I’ve also been updating the client document with any changes or observations they have made before and during testing.
Secondly a new project has begun which I’ve been brought onto. Within the company they are very economical with their intellectual property making and documenting it so as when similar projects appear they can adapt previous work to the new. I am currently involved with helping in the developing document lists which will be distributed to the client.
Another project that the engineers in the office have been working on required help so leaving the WFI Stills for the moment.
I’ve been aiding the engineers in the documentation and cross checking parameters for them in Delta V before factory acceptance testing begins. The project is based around XDR and Wave bioreactors. The aspect I’ve been involved in so far has been cross-checking the parameter values within the phases.
To understand what that means I will briefly explain some concepts.In Delta V the components can be broken down into 2 models, they are the physical and procedural model.
The physical comprises of (as depicted below);
- Sensor(s) (or other control modules) that perform a specific task
- A control model (CM)
- A single or multiple control modules make up an equipment module (EM)
- A single or multiple equipment modules makes up a unit
- Lastly as a single or multiple units make up a process cell.
The procedural control is the structure upon which the automation and control of the physical model is built. This is comprised of phases which make up operations, multiple operations make up unit procedures and they in turn make up the recipe. This is comparable to a baking recipe wherein steps can be broken down and categorized as seen in the below illustrations.
This week the work load has varied and as a result I’ve been mostly working on my online DeltaV training as provided by the company.
The DeltaV training is a basic introduction into the DeltaV by Emerson software package where by the trainee will feel more confident and have a degree of competence in navigating the GUI (graphic user interface) and executing various tasks.
it also goes into some theory of control and automation and shows how one might code in script of through SFCs ( sequential function charts).
