*2 If the read data is any of the following, the meaning of this attribute differs
from the meaning of the comparator value.
When measurement mode is % mode:
+ 999.99: The value exceeds the upper limit of the display range.
-999.99: The value exceeds - 999.98 or the lower limit of the display range.
-999.98: The value is "-----" (comparator value invalid).
+1000.00: The sensor amplifier is in the error status.
When measurement mode is dimension mode:
+99.999: The value exceeds the upper limit of the display range.
-99.999: -99.998 or the lower limit of the display range.
-99.998: The value is "-----" (comparator value invalid).
+100,000: The sensor amplifier is in the error status.
*3 If a write for which a combination of inhibited functions is set is executed,
abnormal setting (1) occurs. For details on each function, refer to "IB Series
User's Manual".
*4 The results of "initial reset request" and "system parameter set request" for
the operation command are also included in this item.
*5 The execution result for the lastly requested item of "zero shift execution
request" or "zero shift request execution request" is read.
*6 You can check the system parameter of the sensor amplifier by reading
"system parameter current state". The system parameter sets a judgement
output, check output polarity, and analog output.
Designate the system parameter set when the operation command executes
"system parameter set request" as "system parameter".
A read or write value is designated by ON/OFF of each of the bits to be
converted to a binary number.
When the read data is "6":
"6" is converted to "0110" in binary representation.
For this reason, the sensor amplifier that read data is set to "NPN
output" and "analog output 1 to 5 V".
*7 Of "tolerance tuning request", "2-point tuning HIGH side 2nd", and "2-point
tuning LOW side 2nd" for the operation command, the execution result for
the lastly requested item is read.
