Words 3 ... 4 Analog Input Register
Each word in this range contains a left justified 15 bit data field. The range is from
0H to 7FFE hex, but the resolution is 14 bit (0 ... 32766 decimal or 0 ... 7FFE hex).
Words 5 ... 8 Words 5 ... 8 are not used.
3x Registers The 3x registers traffic copped to this module are used for input data as follows.
Range
I/O Map Register Data Type
3x + 1 Data for discrete input
3x + 2 Data for analog input channel 1
3x + 3 Data for analog input channel 2
Input Voltage Data is Left
