The 170 ARM 370 30 TSX Momentum I/O base supports 10 discrete inputs and 8 relay outputs. This section contains information about the mapping of the I/O data into input words and output words.
The I/O base must be mapped as one input word and one output word, or as 10 discrete inputs and 8 discrete outputs.
In order to correctly field wire the inputs/outputs and map the input/output data, you need to know which type of Momentum Adapter is mounted on the base .
Adapters may be either IEC compliant or 984 Ladder Logic compliant.

The figure below shows how data is mapped with an IEC Compliant Adapter. When the I/O is mapped as a discrete input point (1x) the MSB is assigned to Pin 1. When mapped as a discrete output (0x) the MSB is assigned to Pin 9. When the I/O is mapped as an input word/register (3x) the LSB is assigned to Pin 1.When mapped as an output word/register, the LSB is assigned to Pin 9.
The figure below shows how data is mapped with a Ladder Logic Compliant Adapter. When the I/O is mapped as discrete input points (0x) the LSB is assigned to Pin 1. When mapped as a discrete output points, the LSB is assigned to Pin 9. When the I/O is mapped as an input word/register (3x) the MSB is assigned to Pin 1. When mapped as an output word/register (4x) , the MSB is assigned to Pin 9.
