These specifications include:. Once your test specifications have been defined, the equipment can be set up and configured for testing. Some cost-impact items to consider include the cost of procuring the equipment, labor and material costs relative to any control, power or communications wiring, and the labor and area to stage the equipment. Keep in mind that while small setups may be very inexpensive, as systems increase in size, so does the impact of planning, space, labor, and costs.
There are other cost considerations as well. Often, the equipment has been purchased with project funds; however, sometimes this equipment needs shipped on-site or to a panel shop for fabrication.
If so, consider purchasing spares and utilizing them for testing. If testing interfaces to legacy systems, you may want to consider end-user spares. Also, particularly if performing prototyping, consider using vendor-supplied equipment to verify functionality before proceeding.
We recommend involving plant personnel from varying responsibilities such as the project engineers, operations managers, operators, and the technical personnel responsible for long-term maintenance of the system. While the presence of multiple roles is helpful to catching any potential problems, there is also the risk of losing focus and getting off-task.
As testing progresses, individuals will find various items they would like changed. To document comments, recommendations, or changes to the system throughout the FAT, we recommend using a System Update Form.
Potential notes may include incorrect results, a change in control philosophy, or even something as simple as the color or formatting of an object on the HMI screen. These changes should be done before going commissioning or installation. The contractor will have only small changes to make in the software documentation rather than a time consuming effort at the end of the project. Best advantage of FAT is another milestone in the project as the software has been proven in design.
The next step is to place SCADA software or equipment in the field and Verify everything again using the real world inputs and outputs.
Before this final stage, the complete system must be tested and commissioned. Step Of Commissioning is usually to verify all of the physical input and output to the each of the PLCs A copy of point list means input and output list can be generated with a column for checking off the points as they are verified. One of the issue is the sense of discrete inputs: are they Normally Open or Normally Closed type. This is thing that can differ between the original design and the field implemented system.
Drug Testing Further, an employee must notify the Employer of any drug statute conviction for a violation occurring in the workplace no later than five 5 days after such conviction. Payment Does Not Imply Acceptance of Work The granting of any payment by the AOC, or the receipt thereof by the Contractor, shall in no way lessen the liability of the Contractor to correct unsatisfactory work in connection with this Agreement.
Random Testing Notwithstanding any provisions of the Collective Agreement or any special agreements appended thereto, section 4. If applied to a worker dispatched by the Union, it will be applied or deemed to be applied unilaterally by the Employer. The Union retains the right to grieve the legality of any imposition of random testing in accordance with the Grievance Procedure set out in this Collective Agreement.
Where the Contractor is responsible for installation, acceptance shall be from completion of installation. Title or other property interest and risk of loss shall not pass from Contractor to the Authorized User until the Products have been accepted. Failure to provide notice of acceptance or rejection or a deficiency statement to the Contractor by the end of the period provided for under this clause constitutes acceptance by the Authorized User s as of the expiration of that period.
The License Term shall be extended by the time periods allowed for trial use, testing and acceptance unless the Commissioner or Authorized User agrees to accept the Product at completion of trial use. Unless otherwise provided by mutual agreement of the Authorized User and the Contractor, Authorized User shall have the option to run testing on the Product prior to acceptance, such tests and data sets to be specified by User.
Where using its own data or tests, Authorized User must have the tests or representative set of data available upon delivery. The test data shall remain accessible to the Authorized User after completion of the test. In the event that the documented installation test cannot be completed successfully within the specified acceptance period, and the Contractor or Product is responsible for the delay, Authorized User shall have the option to cancel the order in whole or in part, or to extend the testing period for an additional thirty.
This type of Acceptance Testing, also known as Alpha Testing, is performed by members of the organization that developed the software but who are not directly involved in the project Development or Testing. This type of Acceptance Testing is performed by people who are not employees of the organization that developed the software. This type of Acceptance Testing is performed by the customers of the organization that developed the software. They are the ones who asked the organization to develop the software.
