4.3 LIO Function
This section explains the local I/O (LIO) function.
4.3.1 Overview
The LIO Module provides 8 digital inputs (DI), 8 digital outputs (DO), and one analog out-
put (AO) channel. The I/O timing has a regular cycle for each of the MP940 levels: System
(S), high-speed (High), and low-speed (Low).
One digital input point can be set for interrupt enable/disable operations.
