注：DeviceNet 总线默认 5根接线，一对电源线，一对 CAN+ CAN- ，一根（中间那根）屏蔽线

（1）ABB标准I/O板DSQC651

DSQC651板主要提供8个数字输入信号、8个数字输出信号和2个模拟输出信号的处理。输入地址0~7，输出地址32~39.模拟输出AO1~A02，地址0~15,16~31.

ABB标准I/O板是挂在DeviceNet网络上的，所以要设定模块在网络中的地址。

（2） ABB标准I/O板DSQC652

DSQC652板主要提供16个数字输入信号和16个数字输出信号的处理。

1. Basic knowledge

1. What is the I/O board of ABB robots?

ABB standard I/O board is the most commonly used interface mode of ABB industrial robots, which is essentially a programmable controller (PLC). It uses a programmable memory used to store instructions for the execution of operations such as logical operations and sequence control, timing, counting and arithmetic operations, and controls various types of mechanical equipment or production processes through digital or analog input (I) and output (O) interfaces.

2, understand ABB industrial robot I/O communication types?

ABB industrial robots can be selected with standard ABB PLC, eliminating the original communication with the external PLC setup trouble, and can achieve PLC-related operations on the robot teaching device. ABB’s standard I/O boards provide common signal processing including digital input DI, digital output DO, analog input AI, and analog output AO.

Note: DeviceNet bus default 5 wires, a pair of power cables, a pair of CAN+ CAN-, one (the middle one) shielded wire

(1) ABB standard I/O board DSQC651

DSQC651 board mainly provides 8 digital input signals, 8 digital output signals and 2 analog output signals processing. Input address 0~7, output address 32~39. Analog output AO1~A02, address 0~15,16~31.

The ABB standard I/O board is hung on the DeviceNet network, so the address of the module in the network must be set.

(2) ABB standard I/O board DSQC652

DSQC652 board mainly provides 16 digital input signals and 16 digital output signals processing.
