Configuring CIP Assembly Numbers
The read and write instance list attributes in the assembly mapping object are bound to two corresponding attributes in the EtherNet/IP host object, according to the following table.
This routes application data to CIP assembly data, by linking CIP instance numbers to assembly mapping object instances.
Note
The lists are matched index-wise, and must thus be of equal length.
Assembly Mapping Object Attribute | Value | Value | EtherNet/IP Host Object Instance Attribute | |
|---|---|---|---|---|
11 - Write PD Instance List | 10 | <—> | 10 | 7 - Producing Instance Number |
11 | <—> | 22 | ||
51 | <—> | 100 | ||
12 - Read PD Instance List | 1 | <—> | 1 | 8 - Consuming Instance Number |
2 | <—> | 2 | ||
30 | <—> | 150 |
Important
For conformity with the CIP specification, both the Write_Assembly_Data and the Read_Assembly_Data services must be implemented.
