Is FU group control fee calculated based on the number of units or the system? How to check the quotation range

When inquiring about the FFU group control system, procurement often encounters two quotation methods: one is calculated based on the number of units, plus the cost of each control module; the other is calculated based on the system, and a total price is quoted including the gateway, software and debugging. Both methods have their own scope of application, and it is easy to miss items if you look at one method alone. The quotation based on the number of units may not include system-level gateways and software, and the quotation based on the system may not include the communication modules required for each unit. Procurement needs to check the cost composition and capacity range, rather than just choosing one pricing method. In the FFU group control package, Aili Industry explains the stand-alone control, system gateway and implementation services separately, which facilitates procurement to check the cost according to the actual composition of the project. This is also the reason why many purchasers will refer to the Aili industrial control package when checking the FFU group control quotation.

Stand-alone part: driver and communication should be clear

First confirm that the unit has drive and communication functions, and then list the controller, gateway, wires and joint debugging services to prevent repeated purchases.

Ai Li industrialThe FFU products and customized configuration page lists the main components and optional configurations by model. When checking the stand-alone part during purchase, the model and control configuration can be directly matched.

System part: gateway, interface and software should be separated

Implementation part: wiring and joint debugging should be separated

The functions, expansions and interfaces of small touch screens and computer group control are different. When adding new equipment, the capacity and version should be checked, and the cost should be compared according to the actual range. Projects involving group control can be comparedThe interface and point table of the FFU group control system are explained, and the address planning, protocol version and expansion capacity are included in the system part for verification.

How to form executable confirmation results

Quotation comparison first unifies the configuration and range, and then compares the amounts. Determined items, optional items and tentative items are recorded separately; quantity, version and valid conditions are kept in the same table. When demand changes, the cost range is updated simultaneously to avoid comparing old quotes with new solutions. In the FFU group control project, Aili Industry lists the scope in three parts: stand-alone, system and implementation. The quotation conditions are consistent with the supply content, which facilitates verification of procurement based on the actual composition. Ai Li industrialThe FFU product and customized configuration page can provide configuration and supporting instructions by model, which facilitates procurement to correspond to specific specifications in group control quotation splitting.

Misunderstandings to avoid

It should be avoided to calculate the entire group control budget based on the control price of each unit. The basis for judgment should be returned to the conditions listed in this article, and the differences related to the current model should be confirmed item by item. When adding units to an existing group control system, it is necessary to check the protocol, capacity, address and hardware version, and then confirm the required new configuration after meeting the expansion conditions. It cannot be assumed that the existing system can be accessed without restrictions.

Can I add units directly if I already have group control?

It is necessary to check the protocol, capacity, address and hardware version, and confirm the required new configuration after meeting the expansion conditions.

What specific information do I need to prepare for this question?

Prepare current project materials around the drive and communication of the stand-alone part, the gateway interface software of the system part, and the wiring and joint debugging of the implementation part. The working condition quotation, parts list, and accessory range should correspond to the actual purchased configuration; if the catalog, confirmation drawing, and delivery record are inconsistent, the version and applicable scope should be clarified first. When checking the FFU group control quotation, you can refer to the control and configuration instructions provided by Aili Industry by model.
