Implementation of EtherNet/IP™
D301271 1013 - FGEN - multi protocol7-10
Process data instances
Instance 101
Contains the station’s input data (static length 256 bytes).
2 Bytes status information (see page 3-22)
+ process data
Instance 102
Contains the station’s output data (static length 256 bytes).
2 Bytes Control data (mapped, but not defined)
+ process data
Instance 103 und Instance 104
In- and output assembly instances with variable assembly sizes. The assembly size is pre-calculated to
support the stations I/O-configuration, enabled diagnostics, etc.
input assembly instance: 103
output assembly instance: 104
The effective size of the Assembly Instance can be determined using the Assembly Object (instance
0×67, attribute 0x04) and can be from 2 to 496 bytes large.
