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
