STEMMANN-TECHNIK 6263246編程控制器
S500 I/O設(shè)備的熱備用功能也可以與07KR51-HSB中央單元、S500輸入/輸出設(shè)備配合使用。當(dāng)使用這些遠(yuǎn)程單元時(shí)，有必要在主控和遠(yuǎn)程熱備用中央單元的程序中實(shí)現(xiàn)一些特定功能來配置它們。這些特定功能的類型和數(shù)量取決于CS31總線上的S500輸入/輸出設(shè)備。特定功能塊用于發(fā)送S500輸入/輸出設(shè)備的配置參數(shù)，對(duì)于每個(gè)設(shè)備，存在兩個(gè)特定功能塊，一個(gè)發(fā)送默認(rèn)設(shè)置，另一個(gè)發(fā)送客戶設(shè)置。使用模塊名稱+S（短），即DC532S，調(diào)用用于發(fā)送默認(rèn)設(shè)置的配置參數(shù)的特定功能塊。特定功能塊S500CONF必須始終在程序中實(shí)現(xiàn)。CS31總線上的DC551-CS31總線模塊必須使用一個(gè)S500CONF功能塊或多次調(diào)用。根據(jù)DC551-CS31總線模塊上的編號(hào)和順序，用于配置模塊的特定功能塊必須與硬配置相匹配。所有這些特定功能塊只能在第一個(gè)PLC循環(huán)期間使用。這些特定功能塊必須導(dǎo)入AC31GRAF編程軟件庫。
07KR51-HSB產(chǎn)品設(shè)計(jì)用于極端工業(yè)環(huán)境。只有應(yīng)用了所有EMC保護(hù)規(guī)則，才能確保這些產(chǎn)品的正確操作。（見技術(shù)文件1SBC260400R1001第4章）組裝條件07KR51-HSB必須使用支撐鎖安裝在DIN導(dǎo)軌（35 mm）上。它可以垂直或水平安裝。對(duì)于機(jī)柜組件：工作溫度為0至55°C，設(shè)想機(jī)組周圍有足夠的自由體積，以允許熱量正確消散。建議機(jī)柜配備通風(fēng)系統(tǒng)。
電源
使用剛性或多導(dǎo)體AWG 14（1.95 mm 2）電線。外部熱熔斷器的連接是提供材料保護(hù)所必需的。選擇開關(guān)位于中央單元或可擴(kuò)展遠(yuǎn)程單元下方時(shí)，可以選擇230 V a.c.或120 V a.c。產(chǎn)品交付時(shí)，選擇器處于230 V交流電位置。120/230 V交流電版本提供內(nèi)部24 V直流電源。該電源為裝置及其擴(kuò)展的二進(jìn)制輸入端供電。該內(nèi)部電源受到短路和過載保護(hù)。在短路或過載的情況下，故障排除后10秒可用。也可以使用外部24 V直流電源。在這種情況下，不要忘記將外部24 V直流電的接地連接到輸入（端子c）的公共接地。所有電氣連接均通過可拆卸接線板實(shí)現(xiàn)，其可接受的導(dǎo)線截面等于2.5 mm 2。作為參考，擰緊扭矩等于0.5 Nm。為了保證遠(yuǎn)距離數(shù)據(jù)傳輸?shù)陌踩蜔o差錯(cuò)，選擇合適的通信電纜非常重要。輸入使用硬導(dǎo)線或多導(dǎo)線AWG 18（0.96 mm 2）至AWG 14（1.95 mm 2）導(dǎo)線，輸出使用硬導(dǎo)線和多導(dǎo)線AWG14（1.95 mm2）導(dǎo)線輸入電纜：見圖至圖。根據(jù)傳感器類型，輸入公共C必須連接到0 V或24 V直流電輸出電纜：參見圖
The hot stand-by functions with S500 I/O device
It is also possible to use with the 07KR51-HSB central units, the S500 input/output devices. When these remotes units are used, it will be necessary to implement in the program of the both hot stand-by central units, master and remote, some specific functions to configure them. The type and the number of these specific functions will depend to S500 input/output devices present on CS31 bus. The specific function blocks are used to send the configuration parameters of the S500 input/output devices, for each device, two specific function blocks exist, one to send the default settings and another to send customer settings. The specific function block to send the configuration parameters with default settings is called with module name +S ( Short ) i.e. DC532S. The specific function block S500CONF has to be always implemented in program. One S500CONF function block must be used by DC551 - CS31 bus module presents on CS31 bus or called several times. The specific function blocks used to configure the modules must match the hard configuration, in term of number and order on DC551 - CS31 bus module. All these specific function blocks must be used only during the first PLC cycles. These specific function blocks must be imported to AC31GRAF programming software library.
The 07KR51-HSB products have been conceived for operation in extreme industrial environments. The correct operation of these products is only ensured if all EMC protection rules have been applied. (see technical documentation 1SBC260400R1001 chapter 4) Assembly conditions The 07KR51-HSB must be mounted on a DIN rail (35 mm) by using the support lock . It may be installed vertically or horizontally. For a cabinet assembly: Operating temperature from 0 to 55°C, envisage sufficient free volume around the units to allow the heat to dissipate correctly. It is recommended that the cabinet is fitted with a ventilation system.
Power supply
Use rigid or multi-conductor AWG 14 (1.95 mm 2 ) wires. The connection of an external thermal fuse is necessary to provides material protection. It is possible to select 230 V a.c. or 120 V a.c. with the selector switch situated underneath the central units or extensible remote units. The products are delivered with the selector in the 230 V a.c. position. An internal 24 V d.c. power supply is available on 120 / 230 V a.c. versions. This power supply feeds the binary inputs of the unit and its extensions This internal power supply is protected against short circuits and overloads. In the case of a short circuit or overload it is available 10 seconds after the fault elimination. It is also possible to use an external 24 V d.c. power supply. In this case do not forget to connect the earth of the external 24 V d.c. to that common to the inputs (terminal C).All electrical connections are realized through removable terminal blocks with an acceptable wire section equal to 2.5 mm 2. The tightening torque, for reference, is equal to 0.5 Nm. In order to guaranty the safety and error free data transmission over long distances, the selection of an appropriate communication cable is very important.Use rigid or multi-conductor AWG 18 (0.96 mm 2 ) to AWG 14 (1.95 mm 2 ) wires for inputs and the rigid or multi-conductor AWG 14 (1.95 mm 2 ) wires for the outputs. - Input cabling: see Figure to Figure. The common C of inputs has to be linked to the 0 V or 24 V d.c. according to the sensor type. - Output cabling: see Figure and Erreur ! Source du renvoi introuvable
