Who should cover the cost of the DCS cable?

Computer power and signal lines, switch signal wires, and printer signal wires should be available already. Cable connections between the control panel and the cabinet, as well as cable connections between the UPS and the cabinet, need to be prepared. I think we should first cooperate to finish the work first. You still haven’t paid the full amount for the project work, right! Koubei

Well, I think the connection cables between the control panel and the cabinets are part of the internal wiring of the system; they are an essential component of it, and therefore should be provided by the system control integrator. As for the cables from the UPS to the cabinets, those should be provided by the owner. In terms of design, the electrical engineering team is responsible for supplying power from the UPS to the cabinets and control panels, and standard technical specifications for PLCs stipulate that the owner shall provide a 220V power supply for use at the cabinets.

You dare to have the agent do the wiring work? The internal wiring of the DCS system is integrated by the manufacturer, but the wiring for external signals entering the system should be done by oneself or by the installation unit; of course, the wiring diagram is provided by Zhejiang Zhongkong.

Formally speaking, it depends on how your contract is drawn up. Informally speaking, before the payment for the project is made, as long as you request it, the agent will usually provide it; after all, they don’t want to engage in a one-time deal

Was your contract set that way! 　

For matters of this kind, it is necessary to refer to the provisions in the contract documents; generally, it is best for these provisions to be clearly stated in the contract in order to avoid disputes. As for your issue, it is best to resolve it through negotiation. If the value of the contract is high, most suppliers can provide it free of charge.

It should be the contractor who installs and routes these cables in place, with the drawings being designed and provided by the manufacturer. The wiring requirements also need to follow those of the manufacturer.

It should be provided by the supplier; he even dares to refuse to give it despite such a trivial matter.

It depends on what the contract specifies; if it’s a turnkey project, then the contractor is responsible for delivering a fully functional system, and you don’t need to worry about anything. But if the construction is to be carried out by several parties, it depends on which party’s contract applies. If the contract does not specify otherwise, generally, the DCS system contractor is responsible for the power supply for the entire control cabinet and the operation station; the UPS is also part of the DCS system, and the wiring for power input and output is also the responsibility of the DCS system contractor. These matters can be negotiated. If the contractors refuse to take on these responsibilities, you can discuss the issue with their supervisors. If they don’t want to do this second project, they can simply choose not to do it, haha. It’s usually done; if it isn’t, there’s no need to use such an excellent construction company.

It’s not a big amount of money, but it’s still quite troublesome when it’s missing. How a contract is drawn up isn’t a big issue; with goodwill and a willingness to resolve problems, this matter can be easily settled. If it’s convenient for you, you can provide it yourself; if something is missing and you have to purchase it separately, it involves a lot of complicated procedures. I don’t think the agent would be so unkind as to refuse to help with such a thing.
