About us
Overview
The 170 AMM 090 01 TSX Momentum I/O base supports 4 analog inputs, 2 analog outputs,4 discrete inputs and 2 discrete outputs. This section contains information about the mapping of the output words into the analog/discrete output values, the usage of output words for channel configuration and the mapping of analog/discrete input values into input words.
I/O Map
The I/O base may be mapped as five contiguous input words and five contiguous output words, as follows:
Word
Input Data
Output Data
1 = LSW
Value, input channel 1
Parameters for input channels 1 ... 4
2
Value, input channel 2
Parameters for output channels 1,2
3
Value, input channel 3
Value, output channel 1
4
Value, input channel 4
Value, output channel 2
5 = MSW
Discrete inputs
Discrete outputs
Discrete I/O Mapping
