描述
主要产品详情及功能
LD 800P主站：HS810是LD 800P链接设备的中央控制单元。该设备专门用于将PROFIBUS PA（过程自动化）网段连接到PROFIBUS DP（分布式外设）网络。
PROFIBUS DP/PA网关：其核心功能是促进PROFIBUS DP（通常用于更快、更高级别的控制）与PROFIBUS PA（用于连接过程自动化应用中的传感器和执行器等现场设备）之间的通信。
协议转换：作为LD 800P的一部分，HS810执行以下基本任务：
电位隔离：对PROFIBUS DP和PROFIBUS PA网段进行电气隔离。
物理层转换：将PROFIBUS DP的RS 485物理配置转换为PROFIBUS PA使用的IEC 61158-2物理配置。
波特率自适应：将PROFIBUS DP传输速率（最高12 MBit/s）适配到PROFIBUS PA的31.25 kBd传输速率。
透明运行：HS810在PROFIBUS网络上透明运行，这意味着它本身不占用PROFIBUS地址，从而简化了网络配置。
自动波特率检测：它可以自动检测PROFIBUS DP端的波特率。
独立于PROFIBUS主站：该设备独立于PROFIBUS主站运行。
设备连接：它最多可连接125个PA设备，从而实现广泛的现场设备集成。
无需配置（基本设置）：对于基本操作，该设备通常无需复杂的配置。
PA设备电源：链接设备LD 800P（包含HS810）可以通过总线直接为PROFIBUS PA站供电。
诊断：通常包含通过LED指示灯指示PROFIBUS网络状态和潜在问题的诊断功能。
可拆卸接线端子：此功能简化了接线和维护。
EMC合规性：设计符合NAMUR NE 21等电磁兼容性(EMC)标准。

Key Product Details and Functions
Head Station for LD 800P:The HS810 is the central control unit for the LD 800P Linking Device.This device is specifically designed to connect PROFIBUS PA(Process Automation)segments to PROFIBUS DP(Decentralized Peripherals)networks.
PROFIBUS DP/PA Gateway:Its core function is to facilitate communication between PROFIBUS DP,which is typically used for faster,higher-level control,and PROFIBUS PA,which is used for connecting field devices like sensors and actuators in process automation applications.
Protocol Conversion:The HS810,as part of the LD 800P,performs essential tasks such as:
Potential separation:Electrically isolating the PROFIBUS DP and PROFIBUS PA segments.
Physical layer conversion:Converting the RS 485 physical arrangement of PROFIBUS DP to the IEC 61158-2 physical arrangement used by PROFIBUS PA.
Baud rate adaptation:Adapting the PROFIBUS DP transfer rate(up to 12 MBit/s)to the PROFIBUS PA transfer rate of 31.25 kBd.
Transparent Operation:The HS810 operates transparently on the PROFIBUS network,meaning it does not occupy a PROFIBUS address itself,simplifying network configuration.
Automatic Baud Rate Detection:It can automatically detect the baud rate on the PROFIBUS DP side.
PROFIBUS Master Independent:The device functions independently of the PROFIBUS master.
Device Connectivity:It can connect up to 125 PA devices,allowing for extensive field device integration.
No Configuration Necessary(for basic setup):For basic operation,the device often requires no complex configuration.
Power Supply for PA devices:The Linking Device LD 800P(which includes the HS810)can provide power supply to PROFIBUS PA stations directly over the bus line.
Diagnostics:It typically includes diagnostic features via LEDs to indicate the status of the PROFIBUS network and potential issues.
Removable Terminal Blocks:This feature simplifies wiring and maintenance.
EMC Compliance:Designed to comply with electromagnetic compatibility(EMC)standards like NAMUR NE 21.
