Multiple Assembly Instances
The Assembly Mapping Object has two arrays on class level (Write PD Instance List and Read PD In-
stance List) listing instances defined by the application. The arrays of attributes 7 and 8 in the EtherNet/
IP host object (Producing Instance Number and Consuming Instance number) are bound to the in-
stance lists in the Assembly Mapping Object. The arrays list the corresponding CIP instance numbers
representing each assembly instance defined by the application.
The example below shows how the EtherNet/IP assembly instances are bound to host application as-
sembly instances.
The length of the arrays must match, otherwise the module enters exception.
