Axioline F analog input module, 8 inputs: 0-10 V, ±10 V, 0-20 mA, 4-20 mA, ±20 mA, 2-wire connection.
NOTE: Only some information in the module data sheet is given below. Please refer to the data sheet itself for more details.
Connections
Input/Output Word
The module is allocated 8 INPUT WORDs and 8 OUTPUT WORDs:
Each INP_W corresponds to an analog input.
The OUT_W are not used.

Data format
The data format indicates how the measurement values (voltage/current/temperature) read/write by Axio modules are represented (in the input/output words of the control).
NOTE: For representation of values outside the range of the scale used, refer to the documentation of the module itself.
All word values in the table under the description column are in decimal format.

The upper word full scale value equals +30000, and the lower word full scale value equals 0 if I have positive range only, otherwise -30000. The unit value of the word equals: (positive range)/30000 |

The upper word unit value is equivalent to +27648, while the lower word unit value is equivalent to 0 if I have positive range only, otherwise -27648. The unit value of the word equals: (positive range)/27648 |

Example
I want to configure channel 4 of the axioline module (r.id 0 slot 1) as follows: Measurement range 4mA ... 20mA, average value with 32 samples, input filter of 12 kHz. The value of the Parameterization word will be: 0x6 + 0x300 + 0x1000 = 0x1306 To give the parameterization I use from shell the command AXIO_WOBJ: AXIO_WOBJ 0 1 0x80 4 0x1306 |
Example
Data format IB IL Range ±10V, if I have the INP_W = -200 then I am reading: -200*(10/30000) = -66.666mV Range 4mA ... 20mA, if I have INP_W = 1 then I am reading: (0.016/27648) + 0.004 = +4.0005333mA (for this range inp_w =0 corresponds to 4mA) Data format S7 compatible Range 0V ... 5V, if I have the INP_W = 3 then I am reading: 3*(5/27648) = +542.5μV Range 0mA ... 20mA, if I have the INP_W = 1 then I am reading: (0.02/27648) = +0.7234μA |
