配置掃描儀
使用SST PROFIBUS配置工具配置掃描儀。您最多可以有4頁248字的輸入數(shù)據(jù)和4頁246字的輸出數(shù)據(jù)。
該工具還允許您在DP網(wǎng)絡(luò)上配置I/O，使您能夠下載通過串行端口或RSLinx驅(qū)動程序配置掃描儀。掃描儀存儲此配置在其閃存中，因此您無需每次啟動CLX時都下載它。
從機的輸入和輸出數(shù)據(jù)映射到ControlLogix 5550控制器的輸入/輸出數(shù)據(jù)數(shù)組，從字節(jié)偏移量4開始。映射取決于您在主服務(wù)器中分配的地址配置1.1.3掃描網(wǎng)絡(luò)和輸入/輸出狀態(tài)掃描儀維護有關(guān)網(wǎng)絡(luò)和輸入/輸出模塊的以下狀態(tài)信息在網(wǎng)絡(luò)上：

1.1.4操作模式SST-PB3-CLX以異步模式運行。一旦卡片上線；PB3-CLX不像PFB CLX那樣等待RPI觸發(fā)Profibus掃描。這是SST-PFB-CLX和SST-PB3-CLX在卡已聯(lián)機。
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.
