Refer to the application object instances. The CAN-8x24 will define the default
assembly object instances according to the following table.
Assembly Object
Instance ID (Hex)
Instance Type
Data Length(Byte)
Component modules
0x64
Output
DO: 5
I-8053/ I-8064/ I-8042
0x65 Input DI:
4
I-8042/I-8057
If the default assembly instances are not adaptive, a user-defined assembly
object can be created. The system will show the unit of IO modules in the CAN
Slave Utility software. Therefore, users can arrange the unit to the specific
assembly instances. In analog modules, the unit of length is 2 bytes where 1
byte is in the digital modules.
Users can assign assembly instances as either input or output instances.
However there must be DO or AO units in output instances. Plus there must be
DI or AI units in input instances. For example:
Assembly Object
Instance ID (Hex)
Instance

Data
Length(Byte)
Component modules
0x64 Output
