369電機(jī)管理繼電器支持強(qiáng)制參數(shù)化。繼電器將其用戶參數(shù)數(shù)據(jù)/設(shè)定點(diǎn)保存在非易失性存儲(chǔ)器中，并且在DP主機(jī)啟動(dòng)期間不需要設(shè)備相關(guān)參數(shù)化。這個(gè)369PC軟件是369設(shè)備用戶參數(shù)化的最佳工具。10.2.2 369MMR-DP配置Profibus DP基本配置有一個(gè)DP主設(shè)備和一個(gè)DP從設(shè)備。在典型的公交路段中，最多32個(gè)車站可以已連接（如果一條總線上有32個(gè)以上的站點(diǎn)運(yùn)行，則必須使用中繼器）。Profibus DP網(wǎng)絡(luò)上的終端節(jié)點(diǎn)必須端接，以避免總線上的反射。如果369電機(jī)管理繼電器用作第一個(gè)或最后一個(gè)網(wǎng)絡(luò)中的模塊，車載終端開關(guān)處于on位置（默認(rèn)為OFF），或外部終端必須使用連接器。
可以使用S1:369 COMMUNICATIONS\Profibus address設(shè)置作為Profibus DP節(jié)點(diǎn)的繼電器的總線地址
設(shè)置點(diǎn)或通過369PC軟件，將地址范圍從1擴(kuò)展到126。地址126僅用于調(diào)試目的，不應(yīng)用于交換用戶數(shù)據(jù)。
現(xiàn)場(chǎng)總線的介質(zhì)是雙絞線銅電纜以及9針SUB-D連接器，它將總線連接到繼電器背面的369插座。369電機(jī)管理繼電器具有自動(dòng)音頻支持。波特率和其他配置所需的從機(jī)特定信息包含在369_xxxx中。gs*，由網(wǎng)絡(luò)配置程序使用。
369電機(jī)管理繼電器作為DP從設(shè)備
根據(jù)主從設(shè)備向DP主設(shè)備傳輸快速過程數(shù)據(jù)道德原則369電機(jī)管理繼電器支持從機(jī)強(qiáng)制（6字節(jié)系統(tǒng)范圍標(biāo)準(zhǔn)化）和從機(jī)特定診斷數(shù)據(jù)。如果診斷被視為高優(yōu)先級(jí)，PLC/主機(jī)程序?qū)⑹盏焦收贤ㄖ▓?bào)警或trip）并可以調(diào)用特殊的錯(cuò)誤例程。當(dāng)369處于模擬模式時(shí)，DP主機(jī)將獲得靜態(tài)診斷消息，這意味著369MMR-DP產(chǎn)生了非進(jìn)程（模擬值），DP主機(jī)應(yīng)停止數(shù)據(jù)與369MMR-DP交換。繼電器的擴(kuò)展診斷由26個(gè)字節(jié)（字節(jié)7至32）組成，包含診斷信息如下表所示。從地址：這是每個(gè)傳輸?shù)牡谝粋€(gè)字節(jié)。它表示從設(shè)備的用戶分配地址即接收主機(jī)發(fā)送的消息。每個(gè)從設(shè)備必須分配一個(gè)唯一的地址，并且只有尋址從設(shè)備將響應(yīng)以其地址開始的傳輸。在主請(qǐng)求傳輸中，SLAVEADDRESS表示請(qǐng)求被發(fā)送到的從設(shè)備的地址。在從屬響應(yīng)傳輸中SLAVE ADDRESS表示發(fā)送響應(yīng)的從設(shè)備的地址。注：帶有SLAVE ADDRESS為0表示廣播命令。廣播命令可用于特定功能。

369實(shí)現(xiàn)了其中一些功能。在主請(qǐng)求傳輸中，功能代碼告訴從設(shè)備要執(zhí)行的操作。在從機(jī)響應(yīng)傳輸中，如果從機(jī)發(fā)送的功能代碼與主機(jī)發(fā)送的指示從機(jī)按要求執(zhí)行功能的功能代碼相同。如果從從設(shè)備發(fā)送的功能代碼為1（即，如果功能代碼>127），則從設(shè)備未按要求執(zhí)行功能，正在發(fā)送錯(cuò)誤或異常響應(yīng)。

The 369 Motor Management Relay supports
mandatory parametrization. The relay keeps its user parameter data / setpoints in a non-volatile memory and does not need device related parametrization during startup of the DP master. The 369PC software is the best tool for user parametrization of the 369 device. 10.2.2 369MMR-DP CONFIGURATION The Profibus-DP basic configuration has one DP master and one DP slave. In a typical bus segment up to 32 stations can be connected (a repeater has to be used if more then 32 stations operate on a bus). The end nodes on a Profibus-DP network must be terminated to avoid reflections on the bus line. If the 369 Motor Management Relay is used as the first or last module in a network the on-board termination switch has be in the ON position (default is OFF), or an external termination connector has to be used. The bus address for the relay as Profibus-DP node can be set using the S1: 369 COMMUNICATIONS \ PROFIBUS ADDRESS setpoint or via the 369PC software, which extends address range from 1 to 126. Address 126 is used only for commissioning purposes and should not be used to exchange user data. The media for the fieldbus is a twisted pair copper cable along with 9-pin SUB-D connector, which connects the bus to the 369 socket on the back of the relay. The 369 Motor Management Relay has autobaud support. The baud rates and other slave specific information needed for configuration are contained in 369_xxxx.gs* which is used by a network configuration program. The 369 Motor Management Relay as a DP slave transfers fast process data to the DP master according to master-slave principle.
The 369 Motor Management Relay supports both slave mandatory (6 bytes system-wide standardized) and slave specific diagnostic data. If the diagnostics are considered hi-priority, the PLC/host program will be informed of the fault (alarm or trip) and can call a special error routine. When the 369 is in Simulation mode, the DP master will get a static diagnostic message, which means the 369MMR-DP produced non-process (simulated values), and the DP master should stop data exchange with the 369MMR-DP. The extended diagnosis for the relay is composed of 26 bytes (bytes 7 to 32) and contains diagnostic information according to the following table.
SLAVE ADDRESS
This is the first byte of every transmission. It represents the user-assigned address of the slave device that is to receive the message sent by the master. Each slave device must be assigned a unique address and only the addressed slave will respond to a transmission that starts with its address. In a master request transmission the SLAVE ADDRESS represents the address of the slave to which the request is being sent. In a slave response transmission the SLAVE ADDRESS represents the address of the slave that is sending the response. Note: A master transmission with a SLAVE ADDRESS of 0 indicates a broadcast command. Broadcast commands can be used for specific functions. FUNCTION CODE: This is the second byte of every transmission. The modbus protocol defines function codes of 1 to 127. The 369 implements some of these functions. In a master request transmission the FUNCTION CODE tells the slave what action to perform. In a slave response transmission if the FUNCTION CODE sent from the slave is the same as the FUNCTION CODE sent from the master indicating the slave performed the function as requested. If the high order bit of the FUNCTION CODE sent from the slave is a 1 (i.e. if the FUNCTION CODE is > 127) then the slave did not perform the function as requested and is sending an error or exception response. DATA: This will be a variable number of bytes depending on the FUNCTION CODE. This may be actual values, setpoints, or addresses sent by the master to the slave or by the slave to the master. Data is sent MSByte first followed by the LSByte. CRC: This is a two byte error checking code. CRC is sent LSByte first followed by the MSByte.
