11.6.3 Process Data Instances
Instance 101
Contains the device’s input data (static length 256 bytes).
2 Bytes status information
+ process data
Instance 102
Contains the device’s output data (static length 256 bytes).
2 bytes control data (mapped, but not defined)
+ process data
Instance 103 and 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.
Process Data Mapping TBEN-Lx-16DIP/TBEN-L4-16DIN
Scheduled diagnostic data mode
