Transferring the J9 Analog Inputs
A Geo Brick Drive MACRO slave with option 12 offers 8 x 12-bit analog inputs on connector J9.
These inputs and outputs are typically mapped using suggested or pre-defined M-Variables at the
following addresses:
Analog Inputs, connector J9
M6991->Y:$003400,12,12,S ; ADC1 Bipolar
M6992->Y:$003402,12,12,S ; ADC2 Bipolar

M6993->Y:$003404,12,12,U ; ADC3 Unipolar
M6994->Y:$003406,12,12,U ; ADC4 Unipolar
M6995->Y:$003408,12,12,U ; ADC5 Unipolar
M6996->Y:$00340A,12,12,U ; ADC6 Unipolar
M6997->Y:$00340C,12,12,U ; ADC7 Unipolar
M6998->Y:$00340E,12,12,U ; ADC8 Unipolar
We will use the MACRO auxiliary MX read commands to transfer the J9 analog inputs. This is done in a
background PLC which copies M6991-M6998 from the slave into eight consecutive self-referenced
Mxx05 variables at the master.

At the slave side, the J9 analog ADC inputs can now be read using these Mxx05 variables.
Note
This setup example assumes that the J9 ADC inputs have been set up
properly at the slave side. See J9 connector setup section.
