2.產(chǎn) 品 詳 情 資 料：
在FOUNDATION Fieldbus H1電纜上安裝連接器。將電纜屏蔽連接到連接器內(nèi)的接地端子，通過(guò)CI582將屏蔽接地。3.將FOUNDATION Fieldbus H1電纜連接至基板上的觸點(diǎn)?；饡?huì)現(xiàn)場(chǎng)總線H1連接將FF H1總線連接到位于TP852基板上的DB9公連接器。有關(guān)設(shè)計(jì)現(xiàn)場(chǎng)總線（連接器、電纜和設(shè)備）的更多信息，NI PXI-8232請(qǐng)參閱現(xiàn)場(chǎng)總線文檔。fieldbus在線可通過(guò)互聯(lián)網(wǎng)網(wǎng)站獲得供應(yīng)商、設(shè)備、服務(wù)和其他現(xiàn)場(chǎng)總線相關(guān)項(xiàng)目的目錄。為現(xiàn)場(chǎng)設(shè)備供電需要現(xiàn)場(chǎng)總線供電的現(xiàn)場(chǎng)設(shè)備需要連接到數(shù)據(jù)線的特殊電源（與現(xiàn)場(chǎng)設(shè)備相同）。為避免現(xiàn)場(chǎng)總線信號(hào)短路，僅使用具有專門為基金會(huì)現(xiàn)場(chǎng)總線設(shè)計(jì)的阻抗特性的電源。請(qǐng)勿為此目的使用SD82x電源設(shè)備。請(qǐng)注意，CI852單元沒(méi)有單元冗余。不能在高完整性控制器中使用。CI852已被CI860通信接口所取代。NI PXI-8232僅因遺留原因而被描述。不可能通過(guò)熱插拔更改CI852單元，也不允許在包含CI852的系統(tǒng)中執(zhí)行固件的在線升級(jí)。NI PXI-8232
Install a connector on the FOUNDATION Fieldbus H1 cable. Connect the cable screen to the ground terminal within the connector to ground the screen via NI PXI-8232. 3. Connect the FOUNDATION Fieldbus H1 cable to the contact on the baseplate. FOUNDATION Fieldbus H1 Connection Connect the FF H1 bus to the male DB9 connector located on the TP852 Baseplate For additional information on designing a fieldbus (connectors, cables and devices), see fieldbus documentation. A catalog referencing suppliers, devices, services and other fieldbus-related items, is available for FIELDBUS ONLINE via the Internet web site. Powering Field Devices Field devices requiring power from the fieldbus need special power supplies connected to the data wires (in the same way as a field device). To avoid shortcircuiting of fieldbus signals, use only power supplies with impedance characteristics specifically designed for FOUNDATION Fieldbus. Do not use SD82x power supply units for this purpose. Note that there is no unit redundancy for the CI852 unit. Cannot be used in High Integrity Controller. CI852 has been replaced by theNI PXI-8232 communication interface. CI852 is only described for legacy reasons. It is not possible to change the NI PXI-8232 unit via hot swap and it is not allowed to perform an online upgrade of firmware in a system containing NI PXI-8232.
