HESG324389控制模块,HESG324389产品颜色
配置扫描仪
使用SST PROFIBUS配置工具配置扫描仪。您最多可以有4页248字的输入数据和4页246字的输出数据。
该工具还允许您在DP网络上配置I/O，使您能够下载通过串行端口或RSLinx驱动程序配置扫描仪。扫描仪存储此配置在其闪存中，因此您无需每次启动CLX时都下载它。
从机的输入和输出数据映射到ControlLogix 5550控制器的输入/输出数据数组，从字节偏移量4开始。映射取决于您在主服务器中分配的地址配置1.1.3扫描网络和输入/输出状态扫描仪维护有关网络和输入/输出模块的以下状态信息在网络上：

1.1.4操作模式SST-PB3-CLX以异步模式运行。一旦卡片上线；PB3-CLX不像PFB CLX那样等待RPI触发Profibus扫描。这是SST-PFB-CLX和SST-PB3-CLX在卡已联机。
Configuring the Scanner
Use the SST PROFIBUS Configuration Tool to configure the scanner. You can have up to 4 pages of
248 words of input data and 4 pages of 246 words of output data.
The Tool also allows you to configure I/O on the DP network, enabling you to download the
configuration to the scanner via the serial port or an RSLinx driver. The scanner stores this
configuration in its flash memory, so you don't need to download it every time you start the CLX.
The input and output data for the slaves is mapped into the ControlLogix 5550 Controller’s I/O Data
arrays, starting at byte offset 4. The mapping depends on the addresses you assign in your Master
configuration.
1.1.3 Scanning Network and I/O Status
The scanner maintains the following status information about the network and the I/O modules
on the network:
•
Active Slave Station Bit table
•
Configured Slave Station Bit table
•
Network diagnostic counters
•
DP master diagnostic counters
1.1.4 Operating Modes
The SST-PB3-CLX operates in Asynchronous Mode. The Module starts scanning as soon as the
card comes online; PB3-CLX does not wait for an RPI to trigger the Profibus scan like the PFB
CLX does. This is the only behavior difference between SST-PFB-CLX and SST-PB3-CLX after
the card has gone online.
