Parameters of Commands and Responses
*3 This data type can only be read when the Detection mode of the sensor amplifiers is "Peak-to-peak" hold.
This data type allows you to read the peak and bottom values during the measurement period.
*4 This data type can only be read when the calculation function is used.
The data can only be read from the main unit (ID: 00) when performing a calculation other than
reference difference. DL-RS1A reads the R.V. values of the expansion units (ID: 01 - 14), which
are used in the calculation, from the main unit. (Only the main unit holds the R.V. values.)
When performing reference difference, the data can only be read from the expansion units. (Only
the expansion units hold the R.V. values.) DL-RS1A reads the R.V. value of the main unit and the
expansion units, which are used in the calculation, from the expansion units.
When using the calculation function, the sensor amplifiers can only hold the P.V. values
of the calculation results.
By using these read commands, the R.V. values of the sensor amplifiers on which the
held calculation result was based can be read. Therefore, it is possible to read the R.V.
value of each sensor amplifier without being affected by the response delay.
*5 When the data read from the sensor amplifiers is one of the following values, it is not a
comparator value but has a specific meaning.
*6 You can read data number "006" to check the error status of the sensor amplifiers.
Convert the five digit number (ASCII characters) read from the sensor amplifiers to a binary
number and check the ON/OFF state of each bit to check the error.
For information on each error, refer to "GT2 Series User's Manual".
• When the data read from a sensor amplifier is "00033":
"33" converted to binary number is "0000 0000 0010 0001".
Therefore, this data indicates that a "number of units error" and an "overcurrent error"
have occurred at the sensor amplifier from which it was read.
• If no error has occurred at the sensor amplifier, the data "00000" is returned.

sensor amplifier
Description
+EEE.EEEE The sensor amplifier is in an error state.
+999.9999 The value exceeds the upper limit of the detection range.
-999.9999 The value is below the lower limit of the detection range.
-999.9998
· In cases such as when using the hold mode, the display
of the P.V. value of the sensor amplifier shows "------".
· When using the GT2-100 Series, the data of the ID out of
the range of the valid ID setting is read.
