You can configure the following operating modes for the individual channels of the X142 interface:

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
Event/period duration measurement	Measurement of number of edges and period duration (e.g. for simple speed measurement with hole mask and light barrier)	---	OB 91/OB 6x required	Required
Pulse width modulation PWM	Output of a configurable pulse-pause ratio with a configurable frequency	---	No OB restrictions	Optional

SNMP常规
常规在该页面对 SNMP 进行基本设置。根据希望应用的功能启用相应的选项。说明SNMP选择 SNMP 协议。可能的设置如下：- “-”（禁用）禁用 SNMP。- SNMPv1/v2c/v3支持 SNMPv1/v2c/v3。提示注意版本 1 和 2c 的 SNMP 不包含任何安全机制。- SNMPv3仅支持 SNMPv3。SNMPv1/v2 只读 (SNMPv1/v2
诊断中断
诊断中断诊断在 STEP 7 (TIA Portal) 的在线和诊断视图中以纯文本形式显示。可通过用户程序评估错误代码。可能指示以下诊断信息：错误 (9H)参数分配错误 (10H)线路断路 (109H)
下载时提示缺少面板映像
使用V15/V15.1/V15.1/V16下载精智(Comfort)系列屏的项目时有时会提示“由于缺少面板映像，下载失败。请安装缺少的面板映像”，造成上述异常的主要原因是V15/V15.1/V16的软件缺少对应的镜像文件。常见问题如下：问题1. 左边项目树下选中触摸屏，点击鼠标右键更改设备/版本，先检查当前设备的版本。以V15的软件版本为例，如下图所示，当前设备版本为13.0.1.0，如果需要使用
组态系统事件
组态系统事件如何访问该功能选择待编辑的模块。在本地安全设置中，选择“日志设置 > 系统事件”(Log settings > System events) 条目。过滤系统事件在该对话框中，设置系统事件的过滤级别。默认情况下，将设置以下值：SCALANCE S：3 级（错误）CP：3 级（错误）记录与所选过滤级别具有相同**级和具有比所选过滤级别更高**级的系统事件。过滤级别的值越低，**
