Analog I/O Slave Unit Functions Section 11-4
Setting Output Value
for Errors
The value that is output when communications errors (time-out and BusOff
errors) occur can be set for each output. The four output settings are set using
the CX-Integrator.
Setting Patterns
Output Ranges and Values
Note When a node address has been used more than once or a Unit error has
occurred, the current output will be 0 mA and the voltage output will be 0 V,
regardless of the setting.
Setting Using the CX-Integrator
1,2,3... 1. Turn ON the power supply to the CompoNet Slave Unit.
2. Double-click the icon of the Slave Unit to set in the Network Configuration
Window to open the Configuration Window. (Alternatively, right-click the
icon and select
Parameters - Edit from the pop-up menu.)
3. Select the Tab Page for the output where the communications error output
value is to be set, and select the desired item from the pull-down menu in
the
Fault State Field.
Low limit Outputs the values in the following table according to the output range.
High limit Outputs the values in the following table according to the output range.
Hold last state Holds and outputs the value from immediately before the error occurred.
Zero count Outputs the value when 0 is written from the Host. This setting will be
affected by scaling settings that are used.
Output range Low limit High limit Hold last state
0 to 5 V –0.25 V 5.25 V Holds value.
1 to 5 V 0.8 V 5.2 V Holds value.
0 to 10 V –0.5 V 10.5 V Holds value.
–10 to 10 V –11 V 11 V Holds value.
4 to 20 mA 3.2 mA 20.8 mA Holds value.
0 to 20 mA 0 mA 21 mA Holds value.
