ABB SB821 3BSE018109R1驱动控制器
I/O系统处理控制器的输入和输出信号。以下是所述系统的部分以及常见类型的信号。I/O系统窗口用于查看和设置先前配置的信号，以及激活和停用I/O单元。I/O系统控制器的I/O系统由I/O总线、I/O单元和I/O信号组成。I/O总线是I/O单元（例如I/O板）的控制器连接，I/O单元包含用于实际信号的通道。I/O总线和单元显示在机器人视图中，作为每个控制器下的子节点，I/O信号显示在I/O窗口中。I/O信号I/O信号用于控制器和外部设备之间的通信，或用于改变机器人程序中的变量。输入信号输入信号通知控制器一些信息，例如，当进给带已定位工件时，它可以设置输入信号。然后可以对输入信号进行编程，以启动机器人程序的特定部分。
The I/O system handles input and output signals to and from the controller. Below are the
parts of the system described, as well as common types of signals.
The I/O system window is used to view and set previously configured signals, and to activate
and deactivate I/O units.
The I/O system
The I/O system of a controller consists of I/O buses, I/O units and I/O signals. The I/O buses
are the controller's connections for I/O units (for instance I/O boards) and the I/O units
contain channels for the actual signals.
The I/O buses and units are displayed in the robot view, as child nodes under each controller
and the I/O signals are displayed in the I/O window.
I/O signals
I/O signals are used to communicate between the controller and external equipment, or to
change variables within a robot program.
Input signals
Input signals notify something for the controller, for instance a feeder belt can set an input
signal when it has positioned a work piece. The input signal can then be programmed to start
a specific part of the robot program.
