Parameters of Commands and Responses
*1 In the Data format column, "*" signifies a number from "0 to 9".
*2 Indicates that the data can only be read from (R), can only be written to (W), or can be both read
from and written to (R/W) the sensor amplifiers.
*3 Since each reset request is a level action, resets are continuously performed as long as the
value is set to 1.
Make sure you send a command format that writes 0 to the sensor amplifiers again after
receiving a response format.
*4 Regardless of the display mode specified on the sensor amplifiers, the range of configurable data
is the same as the "rESo" mode.

Parameters of Commands and Responses
*5 When setting this value to 000.0, no alarm output is made even if the temperature falls below the
indicated temperature setting lower limit; an alarm output is made only when the temperature
exceeds the upper limit.
*6 When setting this value to 100.0, no alarm output is made even if the temperature exceeds the
indicated temperature setting upper limit; an alarm output is made only when the temperature falls
below the lower limit.
*7 To read or write this data type, the analog output of the sensor amplifiers must be set to "Free range
analog" (using data number 051).
Changing the Free range analog upper limit/lower limit is invalid when the analog output is set to
"Standard".
*8 The command is executed only when the setting of the sensor amplifiers is changed from 0 to 1. To
re-execute the command, first change the setting to 0, then change it to 1.
■ Control outputs
This parameter is used with communication command "MS" and DRQ input. Specify the ON/OFF
state of the control output, integrated pulse output, and error alarm output using a one-digit value
(ASCII character).
