Overview
The 170 AAI 140 00 TSX Momentum I/O base supports 16 analog inputs. This section contains information about the mapping of the analog input values into input words and the usage of output words for channel configuration.
I/O Map
The I/O base must be mapped as 16 contiguous input words and four 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 input channels 5 ... 8
3
Value, input channel 3
Parameters for input channels 9 ... 12
4
Value, input channel 4
Parameters for input channels 13 ... 16
5 ... 15
Value, input channel 5 ... 15
Not used
16 = MSW
