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.
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.

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.
