The 170 ADO 540 50 TSX Momentum I/O base supports 16 discrete outputs. This section contains information about the mapping of the I/O data into output words.
The I/O base may be mapped as one output word, or as 16 discrete output points.
In order to correctly field wire the outputs and map the 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 on the I/O base with an IEC Compliant adapter. When the I/O is mapped as discrete points (0x) , the MSB is assigned to Pin 1, and the LSB is assigned to Pin 16. When the I/O is mapped as a word or register (4x), the MSB (bit 15) is assigned to Pin 16, and the LSB (bit 0) is assigned to Pin 1.
