The following table lists the “Input” or “Produced” nibble-wise data for each I/O Module
type
The following table indicates the I/O Assembly Data Attribute mapping for Input
Assemblies.
Nibble-wise Output (Consumed) Assemblies
Instance 100
This output (consumed) assembly was included in the Series B MDSA. Its length (in bytes)
can be calculated as follows:
(I/O module + 1 + (no. of IB2XOB2S modules) / 2
