ABB DC speed regulation DCS500/800 interface board SDCS-IOB-21 3BSE005176R1 inventory

Description

DeviceNet communication protocol is issued by Allen Bradley Company (later merged by Rockwell Automation Company) in the United States, and its communication protocol is based on the controller SDCS-IOB-21 local area network (CAN) developed by Bosch Company. DeviceNet has transplanted the technology from ControlNet (another communication protocol developed by Allen Bradley Company), which is used in conjunction with the local network of the controller, so its cost is lower than that of the traditional RS-485 based communication protocol, but it can be more robust.

In order to promote the use of DeviceNet around the world, Rockwell Automation decided to share this technology with other manufacturers. Later, the DeviceNet communication protocol was managed by ODVA, an independent organization located in the United States. ODVA maintained the specifications of DeviceNe. SDCS-IOB-21 also provided consistency testing to ensure that manufacturers’ products met the specifications of DeviceNet communication protocol.
DeviceNet is also a serial communication link, which can reduce expensive hard wiring. The direct interconnection provided by DeviceNet not only improves the communication between devices, but also provides quite important device level diagnostic functions, which is difficult to achieve through hard wired I/O interfaces.
In addition to providing layer 7 (application layer) definition of ISO model, DeviceNet specification also defines layer 1 (physical transceiver) and layer 0 (transmission medium)
The DeviceNet network can operate 64 nodes at most. The available communication baud rates of SDCS-IOB-21 are 125kbps, 250kbps. and 500kbps respectively.
The device can be powered by the DeviceNet bus (maximum total current is 8A) or by an independent power supply.
1.2 DeviceNet Options
The DeviceNet options of ABB industrial robots include 709-1 DeviceNet Master/Slave and 840-4 DeviceNet Anybus Slave, both of which require corresponding hardware support.
The hardware location corresponding to the 709-1 DeviceNet Master/Slave option is shown in Figure A.
The corresponding board model is DSQC 1006, and the material number is 3HAC043383-001, as shown in the following figure. This board supports the robot to be the master and slave at the same time, and the robot to share a DeviceNet address as the master and slave (set in the robot teaching pendant, the default is 2).
The hardware location corresponding to 840-4 DeviceNet Anybus Slave option is shown at B in the figure below. This option only supports the robot as the slave of DeviceNet (usually used when the robot needs two different URLs on the DeviceNet network). When installing DeviceNet Anybus Slave in the picture, the robot needs the board at A in the figure above. The corresponding board model is DSQC 1003, and the material number is 3HAC046408-001, as shown in the figure below. picture
The corresponding board model at B is DSQC 1004, and the material number is 3HAC045973-001, as shown in the following figure.

1.3 DSQC652 board
The DevikeNet option of ABB robots is introduced above. ABB industrial robots provide several common IO (input/output) boards based on the DevikeNet option, which is convenient for users to directly configure and wire. DSQC652 is the most common board, as shown in the figure below.
