CAN-8123 (I-8KCPS1) / CAN-8223 (I-8KCPS2)
CANopen Remote I/O Unit with 1 or 2 I/O Expansion |
|
|

|

CANopen, a kind of communication protocols,
is based on the intelligent field bus(CAN bus). It was
developed as a standardized embedded network with highly
flexible configuration capabilities. It provides standardized
communication objects for real-time data(Process Data
Objects, PDO), configuration data(Service Data Objects,
SDO), network management data(NMT message, and Error Control),
and special functions(Time Stamp, Sync message, and Emergency
message). Nowadays, CANopen is used in many various application
fields, such as medical equipment, off-road vehicles,
maritime electronics, public transportation, building
automation and etc.
CAN-8123 / CAN-8223 main control unit is specially designed for
the slave devices of CANopen protocol. It follows the CANopen
Spec DS-301 V4.02 and DSP-401 V2.1, and supplies and supplies
many features for users, such as dynamic PDO, EMCY object,
error output value, SYNC cyclic and acyclic, ”Kand etc.
|
In order to expand I/O channel
more flexible, an CAN-8x23 supports 1/2 slot(s) for I/O
expansion and suits with a lot of ICPDAS DI/AI/DO/AO slot
modules. Users can choice DI/DO/AI/AO modules of I-87K series
or I-8000 series to fit the customized practice applications.
In addition, we also provide utility tool to allow users
to create the EDS file dynamically. The EDS file is based
on CANopen SP306 and can be compatible with different CANopen
master interfaces. The application architecture is as image
on the left. |

CAN-8x23 can automatically
scan the I-8K/I-87K modules plugged in the main unit and assigned
these modules to the specific application. Before users apply
the CAN-8x23 in CANopen applications, they must understand the
relationship between these CANopen application and device object
dictionary in CAN-8x23. Therefore, we provide the CAN-8x23 Utility Tool (CAN slave utility, CAN_SL.exe) to allow users to
view the important information, such as slot module information,
Rx and Tx PDO mapping, and device object dictionary. After finishing
the utility configuration, it will create the EDS file for users”¦
CAN-8x23 device. Furthermore, if the CAN-8x23 EDS file is
not needed for users”¦ application, users only need to set the
Node ID and baud by hardware rotary switch. Then, after connecting
the wire and turning on the CAN-8x23, it can work normally on
the CAN bus network through CANopen protocol.
