Parameters of Commands and Responses
Convert the 2-digit number (ASCII characters) read to a binary number and check the ON/OFF
state of each bit to check the judgment output status and check output status.
• When the read data is "05":
"05" is converted to the binary number "0101".
When N.O.
*5 When the read data is one of the following values, it has a different meaning from that of an
evaluation value.
*6 When reading data from the amplifier unit whose "1. Measurement mode" is set to "Dimension
mode", the data format is changed to ±**.*** (Reading range -99.999 to +99.999).
*7 When the sensor amplifier is in the error status or "-----" state, the analog voltage output is
+5.500 and analog current output is +03.00.
*8 When writing is performed to set the prohibited combination of functions, the value becomes 1.
For details of each function, refer to the User's Manual.
*9 When the external input is ON, the external input status is "1" and when it is OFF, the state is "0".
The bit 0,1,2,3 corresponds to the external input 1,2,3,4.
• When the read data is "06":
"6" is converted to the binary number "0110".
*10 This item includes the results for the initial reset request.

Read data Description
+EEE.EE The sensor amplifiers is in the error status.
999.99 The value exceeds the upper limit of the display range.
-999.99 The value is -99.998 or below the lower limit of the display range.
-999.98 The value is "-----".

Parameters of Commands and Responses
*11 You can read data number "056" to check the system parameter of the sensor amplifier.
The system parameter means the polarity of judgment output and check output, and the setting
for analog output.
Convert the 2-digit number (ASCII characters) read to a binary number and check the ON/OFF
state of each bit to check the system parameter.
• When the read data is "006":
"6" converted to binary number is "0110".
Therefore, the setting of the amplifier from which the data is read is "NPN output" and
"Analog output 1 to 5 V".
*12 "Measured correction" and "Logical correction" results can be confirmed.
This cannot be used when "Do not correct" for "Calibration function" is selected.
