Casting line PLC HMI requirements

Casting control objectives

Describe the controls and information your project team needs to discuss. Ask the bidder to identify the proposed control scope for the casting arrangement.

Prepare casting control brief around the information and operator actions your controls reviewer wants to discuss. Identify the proposed equipment configuration and ask which documents describe its control arrangement. Separate questions about the equipment package from questions about connections with site systems, then request the relevant drawings or descriptions so that the assigned reviewer can assess the proposed responsibilities before scope approval. Request a distinction between the information intended for operator review and the information associated with connections to other project systems.

PLC documentation request

Ask for the proposed PLC document schedule and configuration identification. Assign the review of that documentation to your controls engineer.

Prepare plc document questionnaire around the information and operator actions your controls reviewer wants to discuss. Identify the proposed equipment configuration and ask which documents describe its control arrangement. Separate questions about the equipment package from questions about connections with site systems, then request the relevant drawings or descriptions so that the assigned reviewer can assess the proposed responsibilities before scope approval. Request a distinction between the information intended for operator review and the information associated with connections to other project systems.

HMI information needs

Describe the screens and information your operators want reviewed. Request a proposed HMI description addressing those questions without assuming a display function is included.

Prepare hmi requirement brief around the information and operator actions your controls reviewer wants to discuss. Identify the proposed equipment configuration and ask which documents describe its control arrangement. Separate questions about the equipment package from questions about connections with site systems, then request the relevant drawings or descriptions so that the assigned reviewer can assess the proposed responsibilities before scope approval. Request a distinction between the information intended for operator review and the information associated with connections to other project systems.

Control interface boundaries

Provide a diagram of the planned connections with site systems. Ask the bidder to identify the interfaces included in its proposed control package.

In control interface map, identify what lies inside the proposed package and what belongs to the existing project. Name the owner of each side of the connection and the drawing each owner needs to review. Ask the bidder to mark the proposed interface clearly, then have the responsible engineer compare that response with the actual host or adjacent equipment documents used for the enquiry. Request identification of the document defining the existing connection as well as the drawing describing the proposed side of the interface.

Control review demonstration

Ask your controls team to define the proposed review questions. Request the documents and demonstrations needed to assess the quoted control scope.

Use control assessment plan to separate the questions assigned to each project reviewer and the documents needed to answer them. Connect each open question with the proposed item or stage it affects. Ask for a response addressing those questions individually, and have the responsible reviewer record the agreed description that the purchasing team should use when it prepares the request for commercial terms. Ask the assigned reviewer to distinguish a request for more information from approval of the proposed item, so that open questions remain clear.

Control revision records

Request identification of the control configuration and document revisions addressed by the quotation. Reconcile those records before approving the purchase description.

For control revision register, identify the product or equipment item addressed by each requested document. Ask for a document title and the reference needed to connect it with the current proposal. Refer unfamiliar document terminology to the responsible project reviewer, and request clarification where a returned document concerns a different item or configuration from the one described in the purchasing enquiry. Ask the document reviewer to identify which unresolved questions concern missing information and which concern a document referring to the wrong proposed item.
