It is able to work as client or server on the Modbus TCP side, and as a Modbus master or slave, on the other side.

The answer is that these processes give us an organizational background to successfully plan, execute, and manage a well-run project. With that said, let's look at each of these process groups in turn and discover why each is so vital to a project's success.

Initiating According to PMI, the process of Initiating helps to set the vision of what is to be accomplished.

This is where the project is formally authorized by the sponsor, initial scope defined, and stakeholders identified. Stakeholder identification is crucial here because correct identification and subsequent management of stakeholders can literally make or break the project. This process group is performed so that projects and programs are not only sanctioned by a sponsoring entity, but also so that projects are aligned with the strategic objectives of the organization.

Where this is not performed, projects may be started and carried out haphazardly, with no real stated goal or objective. It should also be noted that management chooses and authorizes the project manager here.

It's crucial to authorize and establish the PM early as project managers often have accountability but little authority. Strictly speaking, if you don't formally authorize a project, you don't have a project.

Project Charter and Stakeholder Register. Planning A crucial element of planning is establishing the total scope of the project. While it may appear as though that was accomplished in Initiating, scope along with risks, milestones, summary and budget was defined there at a high level.

Here, through an iterative and more detailed planning process, called progressive elaboration, project documents are developed at a much more detailed level.

While a project team can decide which of those to choose for a given project, the message is clear: Too many organizations start a project with only a cursory amount of planning assuming that - one supposes - everything will fall into place.

But too often, without any real or sufficient planning, chaos prevails. A significant concept in Planning is that the team is able to think the whole project through in advance. So they not only create a variety of plans but also consider all the things that might go wrong risks and how they might respond to them.

For the record, the team should also look for unforeseen things that might benefit them - called opportunities - that they can exploit. What types of plans get created? First and foremost, a project management plan, a document that guides execution of the project.

This is essential in that it becomes an overriding governance document for the entire project. Without going into detail on every single document created, a short list would include: Documents that bound scope what we are and are not doing ; Documents that list detailed requirements; Documents that provide estimates for cost and time; Documents that provide for a schedule; Documents that plan for quality, communications, risk and procurement.

Further we create baselines for scope, schedule and cost against which we can then in Monitoring and Controlling track our progress. And we continue to plan for how we will manage and engage the all-important stakeholders throughout the project life cycle.

A cursory glance at the above will reveal the basic nature of what is accomplished during Planning. It creates your roadmap, your path to success. You should no more fail to prepare these plans than an architect would fail to create a blueprint for a building.

At the end of this process group, the team should have a very good idea of not only what they're tasked to do - what is in and out of scope - but also what it will take to execute the project on-time and on-budget. Project Management Plan, schedule, risk register Executing Naturally, the next thing to do after Planning is to execute, to do the work.

But what's important here is that we now have a project management plan to which we can execute. It helps keep us on track.

Here is where the project team starts doing the work of creating the deliverables while the project manager coordinates those resources. And if that were the only thing that occurred, that might be enough. But there are several other things that must happen during executing.

Since the project team is so important to successful execution, one must assume that developing the team is important to that cause.

So there is an assumption that the project manager will not only acquire and manage the team, but also cultivate it by performing team-building exercises.VxWorks is a real-time operating system (RTOS) developed as proprietary software by Wind River Systems, an Intel subsidiary of Alameda, California, kaja-net.com released in , VxWorks is designed for use in embedded systems requiring real-time, deterministic performance and, in many cases, safety and security certification, for industries, such .

Progressive discipline is the process where you increase the level of severity of your discipline when an employee fails to correct an issue. It’s a common approach because it tends to protect employers from legal action, but not everyone is a fan.

In vxWorks , there are tasks, but no process like Windows or Linux. The tasks are more akin to threads and switching context is a relatively inexpensive operation. In Linux/Windows, switching process is quite expensive. What makes VxWorks so deterministic and fast? Ask Question. as this is something VxWorks handles very well.

then will process scheduling be as fast as in VxWorks? I dont think so.

Process of assigning competent people to fulfill the roles designated for the organizational structure through recruitment, selection and development, induction and orientation of the new staff of the goals, vision, mission, philosophy etc. The planning process may begin with the scheduling of a planned event, the identification of a credible threat, or the initial response to an actual or impending event. Comparison between scheduling algorithms in RTLinux and VxWorks Linköpings Universitet Linköping Round-robin scheduling gives every process with the same priority a pre-set share VxWorks scheduling is thus flexible and adopts easily to the needs of the customer.
