产品详情介绍
STEMMANN-TECHNIK 6263246编程控制器
S500 I/O设备的热备用功能也可以与07KR51-HSB中央单元、S500输入/输出设备配合使用。当使用这些远程单元时，有必要在主控和远程热备用中央单元的程序中实现一些特定功能来配置它们。这些特定功能的类型和数量取决于CS31总线上的S500输入/输出设备。特定功能块用于发送S500输入/输出设备的配置参数，对于每个设备，存在两个特定功能块，一个发送默认设置，另一个发送客户设置。使用模块名称+S（短），即DC532S，调用用于发送默认设置的配置参数的特定功能块。特定功能块S500CONF必须始终在程序中实现。CS31总线上的DC551-CS31总线模块必须使用一个S500CONF功能块或多次调用。根据DC551-CS31总线模块上的编号和顺序，用于配置模块的特定功能块必须与硬配置相匹配。所有这些特定功能块只能在第一个PLC循环期间使用。这些特定功能块必须导入AC31GRAF编程软件库。
07KR51-HSB产品设计用于极端工业环境。只有应用了所有EMC保护规则，才能确保这些产品的正确操作。（见技术文件1SBC260400R1001第4章）组装条件07KR51-HSB必须使用支撑锁安装在DIN导轨（35 mm）上。它可以垂直或水平安装。对于机柜组件：工作温度为0至55°C，设想机组周围有足够的自由体积，以允许热量正确消散。建议机柜配备通风系统。
电源
使用刚性或多导体AWG 14（1.95 mm 2）电线。外部热熔断器的连接是提供材料保护所必需的。选择开关位于中央单元或可扩展远程单元下方时，可以选择230 V a.c.或120 V a.c。产品交付时，选择器处于230 V交流电位置。120/230 V交流电版本提供内部24 V直流电源。该电源为装置及其扩展的二进制输入端供电。该内部电源受到短路和过载保护。在短路或过载的情况下，故障排除后10秒可用。也可以使用外部24 V直流电源。在这种情况下，不要忘记将外部24 V直流电的接地连接到输入（端子c）的公共接地。所有电气连接均通过可拆卸接线板实现，其可接受的导线截面等于2.5 mm 2。作为参考，拧紧扭矩等于0.5 Nm。为了保证远距离数据传输的安全和无差错，选择合适的通信电缆非常重要。输入使用硬导线或多导线AWG 18（0.96 mm 2）至AWG 14（1.95 mm 2）导线，输出使用硬导线和多导线AWG14（1.95 mm2）导线输入电缆：见图至图。根据传感器类型，输入公共C必须连接到0 V或24 V直流电输出电缆：参见图
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
