Introduction

Overview

The BMXERT1604T/H module has16 descrete inputs that can be configured with the following 3 main functions: Counter: This function counts pulses from the discrete input channels. Discrete input: Standard discrete input without time stamping. Time stamping: The discrete input with the time stamps recorded to mark input state changes.

The inputs are in 4 groups that contain 4 input channels in each group. Input functions can be configured by input group:

Input Group	Input Channels	Selectable Functions
0	0, 1, 2, and 3	Only time stamping
1	4, 5, 6, and 7	Counter Discrete input Time stamping (default)
2	8, 9, 10, and 11	Counter Discrete input Time stamping (default)
3	12, 13, 14, and 15	Counter Discrete input Time stamping (default)

To inhibit time stamping for:

a channel in group 0, disable the channel
For a channel in another group, either select a non-time stamping function or disable the channel

Subfunctions of Main Function
