可定義內(nèi)存映射，允許計(jì)算機(jī)通過(guò)使用一個(gè)Modbus數(shù)據(jù)包讀取多達(dá)124個(gè)非連續(xù)數(shù)據(jù)寄存器（設(shè)定值或?qū)嶋H值）。主計(jì)算機(jī)經(jīng)常需要連續(xù)輪詢每個(gè)連接的從屬繼電器中的各種值。如果這些值分散在整個(gè)內(nèi)存映射中，那么讀取它們將需要多次傳輸，并會(huì)給通信鏈路帶來(lái)負(fù)擔(dān)。用戶可定義存儲(chǔ)器映射可編程為將任何存儲(chǔ)器映射地址連接到連續(xù)用戶映射位置塊中的一個(gè)，從而可以通過(guò)讀取這些連續(xù)位置來(lái)訪問(wèn)它們。用戶可定義區(qū)域有兩個(gè)部分：1。包含125個(gè)實(shí)際值或設(shè)定點(diǎn)寄存器地址的寄存器索引區(qū)（存儲(chǔ)器映射地址0180h至01FCh）。2.寄存器區(qū)域（存儲(chǔ)器映射地址0100h至017Ch），其包含寄存器索引中的地址處的數(shù)據(jù)。在存儲(chǔ)器映射的其余部分中分離的寄存器數(shù)據(jù)可以重新映射到用戶可定義寄存器區(qū)域中的相鄰寄存器地址。這是通過(guò)寫(xiě)入用戶可定義的寄存器索引區(qū)域中的寄存器地址來(lái)實(shí)現(xiàn)的。這允許改進(jìn)數(shù)據(jù)的吞吐量，并且可以消除對(duì)多個(gè)讀取命令序列的需要。例如，如果需要從469中讀取平均相電流（寄存器地址0306h）和熱測(cè)試定子RTD溫度（寄存器地址0320h）的值，則其地址可重新映射如下：1。使用功能代碼06或16將0306h寫(xiě)入地址0180h（用戶可定義寄存器索引0000）。2.使用功能代碼06或16將0307h寫(xiě)入地址0181h（用戶可定義寄存器索引0001）。（平均相電流為雙寄存器數(shù)）3。使用功能代碼06或16將0320h寫(xiě)入地址0182h（用戶可定義寄存器索引0001）。寄存器0100h（用戶定義寄存器0000）和0101h（用戶可定義寄存器0001）的讀取（功能代碼03或04）將返回A相電流，寄存器0102h（用戶可自定義寄存器0002）將返回?zé)釡y(cè)試定子RTD溫度。6.3.3事件記錄器469事件記錄器數(shù)據(jù)從地址3000h開(kāi)始。地址3003h是指向感興趣事件的指針（1表示最新事件，40表示最早事件）。要檢索事件1，請(qǐng)將“1”寫(xiě)入事件記錄選擇器（3003h），并從3004h到3022h讀取數(shù)據(jù)。要檢索事件2，請(qǐng)將“2”寫(xiě)入事件記錄選擇器（3003h），并從3004h到3022h讀取數(shù)據(jù)。可以以這種方式檢索所有40個(gè)事件。每個(gè)事件的時(shí)間和日期戳可用于確保按順序檢索所有事件，而新事件不會(huì)破壞事件序列（事件1應(yīng)比事件2更近，事件2應(yīng)比事件3更近，等等）每次在跟蹤緩沖區(qū)中發(fā)生跳閘時(shí)，A/D采樣。跟蹤緩沖區(qū)根據(jù)S1 PREFERENCES？跟蹤內(nèi)存緩沖區(qū)設(shè)置點(diǎn)進(jìn)行分區(qū)。使用S1 PREFERENCES?Trace Memory Trigger（S1優(yōu)先）設(shè)定值設(shè)置跟蹤存儲(chǔ)器觸發(fā)器，這決定了存儲(chǔ)了多少跳閘前和跳閘后循環(huán)。跟蹤緩沖區(qū)帶有時(shí)間和日期戳，并且可以與事件記錄中的行程相關(guān)。當(dāng)跳閘發(fā)生時(shí)，以這種方式捕獲10個(gè)波形。這是3相電流、3個(gè)差分電流、接地電流和3個(gè)電壓波形。該信息存儲(chǔ)在易失性存儲(chǔ)器中，如果繼電器通電，該信息將丟失。要訪問(wèn)捕獲的波形，請(qǐng)通過(guò)將其跟蹤存儲(chǔ)器通道（見(jiàn)下表）寫(xiě)入跟蹤存儲(chǔ)器通道選擇器（地址30F1h）來(lái)選擇感興趣的波形。然后將跟蹤存儲(chǔ)器數(shù)據(jù)從地址3100h讀取到3400h。每個(gè)周期有12個(gè)樣本。讀取的值以實(shí)際安培或伏特為單位。地址30F8h僅顯示進(jìn)入一個(gè)相位的數(shù)量，并驗(yàn)證測(cè)量值的準(zhǔn)確性。查看測(cè)量值：A2 METERING DATA（測(cè)量數(shù)據(jù)）電流測(cè)量b）1 A INPUT（輸入）1。用電壓表改變以下電流5 A單位預(yù)期電流讀數(shù)測(cè)量值V DC。執(zhí)行以下步驟以驗(yàn)證數(shù)字輸入的功能。1.打開(kāi)所有數(shù)字輸入和跳閘線圈監(jiān)控電路的開(kāi)關(guān)。2.查看數(shù)字輸入和跳閘線圈監(jiān)控的狀態(tài)：實(shí)際值A(chǔ)1狀態(tài)×數(shù)字輸入3。關(guān)閉所有數(shù)字輸入和跳閘線圈監(jiān)控電路的開(kāi)關(guān)。
Definable Memory Map, which allows a computer to read up to 124 nonconsecutive data registers (setpoints or actual values) by using one Modbus packet. It is often necessary for a master computer to continuously poll various values in each of the connected slave relays. If these values are scattered throughout the memory map, reading them would require numerous transmissions and would burden the communication link. The User Definable Memory Map can be programmed to join any memory map address to one in the block of consecutive User Map locations, so that they can be accessed by reading these consecutive locations. The User Definable area has two sections: 1. A register index area (memory map addresses 0180h to 01FCh) that contains 125 actual values or setpoints register addresses. 2. A register area (memory map addresses 0100h to 017Ch) that contains the data at the addresses in the register index. Register data that is separated in the rest of the memory map may be remapped to adjacent register addresses in the User Definable Registers area. This is accomplished by writing to register addresses in the User Definable Register Index area. This allows for improved through-put of data and can eliminate the need for multiple read command sequences. For example, if the values of Average Phase Current (register address 0306h) and Hottest Stator RTD Temperature (register address 0320h) are required to be read from an 469, their addresses may be remapped as follows: 1. Write 0306h to address 0180h (User Definable Register Index 0000) using function code 06 or 16. 2. Write 0307h to address 0181h (User Definable Register Index 0001) using function code 06 or 16. (Average Phase Current is a double register number) 3. Write 0320h to address 0182h (User Definable Register Index 0001) using function code 06 or 16. A read (function code 03 or 04) of registers 0100h (User Definable Register 0000) and 0101h (User Definable Register 0001) will return the Phase A Current and register 0102h (User Definable Register 0002) will return Hottest Stator RTD Temperature. 6.3.3 EVENT RECORDER The 469 event recorder data starts at address 3000h. Address 3003h is a pointer to the event of interest (1 representing the latest event and 40 representing the oldest event). To retrieve Event 1, write ‘1’ to the Event Record Selector (3003h) and read the data from 3004h to 3022h. To retrieve Event 2, write ‘2’ to the Event Record Selector (3003h) and read the data from 3004h to 3022h. All 40 events may be retrieved in this manner. The time and date stamp of each event may be used to ensure that all events have been retrieved in order without new events corrupting the sequence of events (Event 1 should be more recent than Event 2, Event 2 should be more recent than Event 3, etc.). NOTE GE Multilin 469 Motor Management Relay 6-11 6 COMMUNICATIONS 6.3 MEMORY MAP 6 6.3.4 WAVEFORM CAPTURE The 469 stores a number of cycles of A/D samples each time a trip occurs in a trace buffer. The trace buffer is partitioned according to the S1 PREFERENCES ?× TRACE MEMORY BUFFERS setpoint. The Trace Memory Trigger is set up with the S1 PREFERENCES ?× TRACE MEMORY TRIGGER setpoint and this determines how many pre-trip and post-trip cycles are stored. The trace buffer is time and date stamped and may be correlated to a trip in the event record. 10 waveforms are captured this way when a trip occurs. These are the 3 phase currents, 3 differential currents, ground current and 3 voltage waveforms. This information is stored in volatile memory and will be lost if power is cycled to the relay. To access the captured waveforms, select the waveform of interest by writing its trace memory channel (see following table) to the Trace Memory Channel Selector (address 30F1h). Then read the trace memory data from address 3100h to 3400h. There are 12 samples per cycle for each of the cycles. The values read are in actual amperes or volts. Address 30F8h shows the number of into one phase only and verify accuracy of the measured values. View the measured values in: A2 METERING DATA ? CURRENT METERING b) 1 A INPUT 1.
