ATLAS TC-4000-S電源控制器
COMV通信變量。這是FIP網絡上I/O數據的交換單位。
COMV只有一個生產者。它分布在網絡上,可以由所有其他網絡用戶消費。COMV攜帶一個或多個傳輸變量(TVA)。連接點設備通過連接點邏輯連接到網段,該連接點:對應于訂戶號碼。只允許一個邏輯連接點每個設備。消費者在網絡上消耗系統或應用程序變量(或COMV)的設備。詳細信道狀態字
可使用“檢索詳細信息”通道檢索此可選狀態數據狀態命令。故障觸點可包含在90-70系列應用程序中的邏輯觸點PLC。這些觸點可用于檢測故障和缺少報告的故障條件通過FIP總線控制器。
菲普工廠儀表協議全FIP芯片Series 90-70 FIP總線控制器上的硬件組件,
用于管理FIP總線控制器和網絡之間的通信
通用設備用于指定支持通信標準EN 50170的設備的術語(WorldFip簡介)。這包括可集成到中的第三方設備FIP系統。通用設備僅與PLC交換數據,操作控制站或其他通用設備。交換始終由字節表組成
由用戶識別的MPS通信變量(COMV)攜帶。大循環在FIP總線的一次掃描期間發生的一組操作。主設備遠程I/O機架的操作模式由主設備控制,以:其被附接。每個遠程I/O機架只有一個主設備。然而同一網段上可以有多個遠程I/O機架主設備。在FIP網絡中,所有設備也被稱為訂戶。一個或多個作為主用戶。主訂戶將配置文件存儲到訂戶,控制用戶的操作模式,并報告在網絡上發現的故障。MPS(制造定期服務)交換
MPS是FIP網絡的應用層之一。它特別包括:及時和更新的概念。
定期MPS交換是異步的,如果僅交換時間段插槽由用戶定義。
如果交換時隙的周期為以及時間最早的開始時刻和最晚的結束時刻插槽由用戶定義。
網段一個網段最多可支持由中繼器互連的四個部分。
每個部分最多可支持32個訂戶,總共可支持128個訂戶。
COMV
COMmunication Variable. This is the unit of exchange for I/O data on a FIP network.
A COMV has only one producer. It is distributed on the network and can be
consumed by all the other network subscribers. A COMV carries one or several
transport variables (TVAs).
Connection Point
A device is logically connected to a network segment by a connection point that
corresponds to a subscriber number. Only one logical connection point is permitted
per device.
Consumer
A device that consumes a system or application variable (or COMV) on the network.
Detailed Channel Status Words
This optional status data may be retrieved using the Retrieve Detailed Channel
Status Command.Fault Contacts
Logical contacts that can be included in the application program of the Series 90-70
PLC. These contacts can be used to detect fault and lack of fault conditions reported
by the FIP Bus Controller.
FIP
Factory Instrumentation Protocol
Full FIP Chip
The hardware component on the Series 90-70 FIP Bus Controller that manages
communications between the FIP Bus Controller and the network.
Generic Device
Term used to designate devices supporting Communication Standard EN 50170
(WorldFip profile). This includes third party devices that can be integrated into the
FIP system. A generic device exchanges data only with PLCs, operating Control
Stations or other generic devices. The exchange always consists of a table of bytes
carried in an MPS communication variable (COMV) that is identified by the user.
Macrocycle
The set of operations that occurs during one scan of the FIP bus.
Master Device
The operating modes of a remote I/O rack are controlled by the master device to
which it is attached. There is only one master device per remote I/O rack. However,
there can be several remote I/O rack master devices on the same network segment.In a FIP Network, all of the devices are also known as subscribers. One or more acts as
a Master Subscriber. The Master Subscriber stores configuration files to the subscribers,
controls the subscribers’ operating mode, and reports faults discovered on the network.
MPS (Manufacturing Periodic Services) Exchanges
MPS is one of the application layers of the FIP network. It consists, in particular, of
the notions of promptness and refresh.
The periodic MPS exchange is asynchronous if only the period of the exchange time
slot is defined by the user.
The periodic MPS exchange is synchronous if the period of the exchange time slot as
well as the earliest beginning moments and the latest ending moments of the time
slot are defined by the user.
Network Segment
A network segment can support up to four sections interconnected by repeaters.
Each section can support up to 32 subscribers, for a total of up to 128 subscribers.
