IS220PVIBH1A的功能是什么?

IS220PVIBH1A是一款Mark VIe振動(dòng)監(jiān)視器I/O包，連接到Mark VIe系統(tǒng)的終端板上。
產(chǎn)品描述
IS220PVIBH1A模型被設(shè)計(jì)為振動(dòng)監(jiān)測(cè)包。PVIB包的主要功能是提供多達(dá)兩個(gè)I/O以太網(wǎng)網(wǎng)絡(luò)和振動(dòng)終端板之間的電氣接口功能。該包的主要組件是與大多數(shù)MK VIe分布式I/O包以及子板和采集板一起使用的主處理器板。

該組件上有13個(gè)通道，用于通過(guò)以下幾種傳感器類型收集和讀取接近度和振動(dòng)信息:

Velomitor

地震

Proximitors

加速度計(jì)

IS220PVIBH1A

傳感器類型用于不同的通道，例如，加速度計(jì)僅用于通道1、2和3。請(qǐng)注意，通道9、10、11和12只能用于支持近端，而第13通道可以輸入近端類型或鍵相量信號(hào)類型。請(qǐng)注意，IS220PVIBH1A包上的13個(gè)差分輸入有一個(gè)DAC(數(shù)字模擬轉(zhuǎn)換器)，用于偏置調(diào)整，可以使信號(hào)的DC內(nèi)容無(wú)效，從而更好地集中a /D(模數(shù))輸入范圍。

PVIB I/O包有一個(gè)處理器應(yīng)用程序代碼，用于潛在地包含允許包從單或雙以太網(wǎng)輸入操作所需的所有邏輯代碼。當(dāng)從兩個(gè)以太網(wǎng)輸入操作時(shí)，正確操作IS220PVIBH1A包所需的網(wǎng)絡(luò)路徑始終處于活動(dòng)狀態(tài)。如果由于任何原因其中一個(gè)網(wǎng)絡(luò)發(fā)生故障，它不會(huì)對(duì)I/O包的操作造成任何類型的干擾，但故障將通過(guò)操作網(wǎng)絡(luò)連接指示。

IS220PVIBH1A的回顧
內(nèi)部審查
(5.0)
PVIB包中有一個(gè)用于運(yùn)行應(yīng)用程序代碼的功能，與傳統(tǒng)的熱備份系統(tǒng)相比，該功能通常更能容忍接收任何類型的故障，后者僅在檢測(cè)到主端口故障后才使用第二個(gè)端口。由于這個(gè)功能，PVIB包優(yōu)于使用熱備份系統(tǒng)的模型。- AX控制技術(shù)團(tuán)隊(duì)

FAQ about IS220PVIBH1A
What is the function of IS220PVIBH1A?

The IS220PVIBH1A is a Mark VIe vibration monitor I/O package that connects to the terminal board of the Mark VIe system.
Product description
The IS220PVIBH1A model is designed as a vibration monitoring package. The main function of the PVIB package is to provide electrical interface function between up to two I/O Ethernet networks and vibrating terminal boards. The main component of the package is the main processor board used with most MK VIe distributed I/O packages, as well as the daughter board and acquisition board.

There are 13 channels on the assembly for collecting and reading proximity and vibration information through the following sensor types:

Velomitor

earthquake

Proximitors

accelerometer

Sensor types are used for different channels, for example, accelerometers are only used for channels 1, 2, and 3. Note that channels 9, 10, 11 and 12 can only be used to support the near end, while channel 13 can input either the near end type or the key phasor signal type. Note that the 13 differential inputs on the IS220PVIBH1A packet have a DAC(digital-to-analog converter) for bias adjustment that can invalidate the DC content of the signal to better focus the a /D(analog-to-digital) input range.

The PVIB I/O packet has a processor application code that is used to potentially contain all the logic code needed to allow the packet to operate from single or dual Ethernet inputs. When operating from both Ethernet inputs, the network path required for proper operation of the IS220PVIBH1A packet is always active. If for any reason one of the networks fails, it will not cause any type of interference with the operation of the I/O packet, but the failure will be indicated through the operational network connection.

Review of IS220PVIBH1A
Internal review
(5.0)
There is a feature in the PVIB package for running application code that is generally more tolerant of receiving any kind of failure than a traditional hot backup system, which uses the second port only after detecting a failure on the primary port. Because of this capability, PVIB packages are superior to models that use hot backup systems. – AX Control Technical team
