在第14節(jié)（IPU-237）中添加以下變更
第14-15頁，在表14-11中，關(guān)于LED 1-8添加以下內(nèi)容：如果模擬通道正常，則LED點(diǎn)亮。然后，如果HART消息交換正確發(fā)生，LED將閃爍100毫秒。如果模擬信道正常，并且模塊發(fā)送消息但未收到正確響應(yīng)，則LED將閃爍400毫秒。從版本0C開始，RSR固件支持級聯(lián)PI配置，其中PI 1的輸出用作PI 2的目標(biāo)位置輸入。支持級聯(lián)操作的其他功能包括選擇直接/間接PI操作的標(biāo)志，以及稱為“后退”的防纏繞功能。這些新功能中的一些實(shí)際上獨(dú)立于級聯(lián)，但所有這些都在本文中詳細(xì)描述。第22-9頁，刪除校準(zhǔn)模式部分下完全校準(zhǔn)項(xiàng)目符號第二段（任意極限…10.0伏）后的所有剩余段落（六）：第22-9.頁，添加以下信息代替上述項(xiàng)目中刪除的段落：當(dāng)要求完全校準(zhǔn)時(shí)，閥門首先行程至0%。在0%時(shí)，解調(diào)器增益被調(diào)整，直到反饋電壓接近10伏。此時(shí)解調(diào)器增益是最大可能的解調(diào)器增益。然后閥移動到100%。如果電壓大于10伏或超出刻度，解調(diào)器增益將降低，并讀取電壓讀數(shù)。該讀數(shù)為100%標(biāo)定閥。然后，閥門移動至0%，并讀取電壓讀數(shù)。該讀數(shù)為0%校準(zhǔn)值。確定0%校準(zhǔn)閥后，新值寫入EE存儲器。
INTRODUCTION
The FBM242 Termination Assembly is part of the I/A Series DIN rail mounted FBM subsystem field wiring termination family. Each FBM242 Termination Assembly and its associated termination cable provide active signal interfacing and connection between sixteen 2-wire externally sourced solid-state switched outputs and the FBM242 Channel Isolated Externally Sourced Discrete Output Interface Module. The termination assembly’s output switching supports externally sourced 120 V ac or 125 V dc. Per channel fuses limit output current to a maximum of 2 A. FEATURES Key features include: ? Combination foot that supports 32 or 35 mm DIN rail mounting ? Multiple, integrated marking systems ? Distinct family group color ? Normally open, solid-state switched outputs ? Active per channel output fuse protection with bidirectional blown fuse indication (dc polarity independent) ? Per channel output knife disconnect and test sockets.Signal Output(a) 16 channel, externally sourced solid-state switch Channel isolation provided by termination assembly RATING(a) 132 V ac at 2 A maximum with resistive load or 20 mH maximum inductive load without snubber metal oxide varistor (MOV) 150 V dc at 2 A maximum with resistive load or 50 mH maximum inductive load without snubber diode INRUSH CURRENT 20 A peak for 16 ms maximum LEAKAGE CURRENT <1 mA ON RESISTANCE <100 m ? at 20°C HEAT DISSIPATION 7.0 W maximum
Add the Following Changes to Section 14 (IPU-237)
Page 14-15, In Table 14-11, regarding LED’s 1-8 add the following: If the analog channel is healthy, the LED is illuminated. Then, if a HART message exchange occurs correctly, the LED is blinked off for 100 mSec. If the analog channel is healthy, and if the module sends a message and does not receive a correct response, the LED is blinked off for 400 mSec.Starting with revision 0C, RSR firmware supports a cascaded PI configuration in which the output of PI 1 is used as the target position input for PI 2. Additional features to support cascading operation are flags to select direct/indirect PI operation, and an anti-windup feature called “retreat”. Some of these new features are actually independent of cascading, but all are described in detail in this document. Page 22-9, Delete all of the remaining paragraphs (six) after the second paragraph (Arbitrary limits...10.0 volts.) in the Full Calibration bullet under the Calibrate Mode Section: Page 22-9, Add the following information in place of the deleted paragraphs in above item: When full calibration is requested, the valve first travels to 0%. At 0%,demodulator gain is adjusted until the feedback voltage is near 10 volts. The demodulator gain at this point is the maximum possible demodulator gain. Then the valve travels to 100%. If the voltage is greater than 10 volts, or off-scale, demodulator gain is reduced, and a reading of the voltage is taken. This reading is the 100% calibration valve. Then the valve travels to 0% and a voltage reading is taken. This reading is the 0% calibration value. After the 0% calibration valve is determined, the new values are written to EE memory.
