列表: Overview of operating modes

Operating mode of X142 I/Os (8 channels)	Functionality	Use with technology objects (TOs)	Use via I/O area (without TO)	Isochronous mode
DI	Digital input Input delay (1 μs/125 μs) Hardware interrupt (optional) Hardware interrupt at rising and/or falling edge	Hardware limit switch for positioning and synchronous axes	No OB restrictions	Optional
DQ	Digital output	Output cam Cam track	No OB restrictions	Optional
Timer DI	Acquisition of the switching time of a digital input ** with up to two edges per application cycle (e.g. for use as measurement sensing input)	Measuring input (OB 91 required)	OB 91/OB 6x required	Required
Timer DQ	Precisely timed output of a digital output ** with up to two edges per application cycle (e.g. for use as an output cam output)	Output cam (OB 91 required) Cam track (OB 91 required)	OB 91/OB 6x required	Required
Oversampling DI	Acquisition of 32 states of a digital input ** at equal intervals per application cycle	---	OB 91/OB 6x required	Required
Oversampling DQ	Output of 32 states of a digital output ** at equal intervals per application cycle	---	OB 91/OB 6x required	Required

OPC UA 示例組態(tài)
OPC UA 示例組態(tài)以下部分介紹了如何使用客戶端接口編輯器和連接參數(shù)分配。說明基于特定示例：兩個(gè) S7-1500 CPU 在系統(tǒng)中運(yùn)行：一個(gè) CPU 用作 OPC UA 客戶端，另一個(gè)用作 OPC UA 服務(wù)器。其它制造商生產(chǎn)的控制器、傳感器和 IT 系統(tǒng)當(dāng)然也可用作 OPC UA 客戶端或服務(wù)器。特別值得一提的是，在不同系統(tǒng)之間進(jìn)行數(shù)據(jù)交換（互操作性）是 OPC UA 的主要優(yōu)點(diǎn)。使用示例說明
