Discrete I/O Points and IEC Compliant Data Mapping
Overview
The 170AMM11030 base returns 16 discrete input bits to the processor in one 16-
bit word (3x). The input points are field wired to row 2 of the base. The processor
sends 8 discrete output bits to the base as a single 16-bit word (4x). The output
points are field wired to row 3.
