Summary of the Analog Input Slave Units
Section 6-2
■
Input Range: 0 to 20 mA
Current of 0 to 20 mA is converted to data from 0000 to 1770 Hex (0 to 6000).
The input data range for which conversion is possible is
–
1 to +21 mA and
here the output data is FED4 to 189C Hex (
–
300 to +6300). When input data
is a negative voltage, it is expressed as the two's complement (hexadecimal)
and the output data for a disconnected line is the same as for an input of 0 mA
(0000 Hex).
■
Input Range: 4 to 20 mA
Current of 4 to 20 mA is converted to data from 0000 to 1770 Hex (0 to 6000).
The input data range for which conversion is possible is 3.2 to 20.8 mA and
here the output data is FED4 to 189C Hex (
–
300 to +6300). If the input value
falls below the input range such as for a disconnected line (input current is
less than 3.04 mA), a disconnected line detection function activates and data
is set to 7FFF Hex.
Input Range Settings
Setting of input range is performed using Analog Input Slave Unit DIP
switches, CX-Integrator, or Explicit message.
The method for setting the input range using CX-Integrator is described
below.
Please see "
11-1 CX-Integrator
" on page 481 regarding details for CX-Inte-
grator.

1.
Turn ON the power to the CompoNet Slave Unit.
2.
Double-click the icon of the Slave to be set in the Network Configuration
Window to open the Configuration Window. (Alternatively, right-click the
Slave Unit icon and select
Parameters - Edit
from the menus.)
