9 Non-cyclical data
Explicit EtherNet/IP messages allow exchange of further data with the CPC12 controller and the circuit protectors. Access also
allows direct addressing of a circuit protector. EtherNet/IP Class, Instance and Attribute are required. For reading and editing
CPC12 data, Class 100 is used. Class 101 is used for reading and editing the data of circuit protectors. The access to the circuit
protectors is divided into channels. Two channels are provided per circuit protector.
The non-cyclical access to the data of CPC12 is divided as follows:
Class 100 and Class 101 support only service codes Get_Attribute_Single (14) and Set_Attribute_Single (16).
The non-cyclical access to the data of circuit protectors and/or channels is divided as follows:
