*10 The result of the "initial reset request" motion command is included in this item.

Regarding Data No. 53 (EEPROM writing result), a "0: writing in progress" status is
maintained for 2 seconds after completion of the final write command transmission
to the nonvolatile memory (EEPROM). Writing begins 2 seconds later, and if
completed normally, the result is "1: successfully completed".
Example:
After every-second write command transmissions, a "0: writing in progress" status is
established for 2 seconds. A "0: writing in progress" status is maintained for 2
seconds after completion of the final write command transmission, and writing then
begins 2 seconds later, with a result of "1: successfully completed".
However, writing begins immediately following a initial reset executed in response to
a Data No. 5 "initial reset request". A "1: successfully completed" result then occurs
if all parameters have been saved to the nonvolatile memory (EEPROM)
approximately 3 seconds later.

•

When "zero shift status save" is ON, writing begins immediately for Data No. 1
"zero shift request" and Data No. 2 "zero shift reset request".

•

When the "adjust status save" function is ON, writing begins immediately for Data
No. 11 "adjust request" and Data No. 12 "adjust reset request".

•

Writing also begins immediately for Data No. 12 "reference light intensity
registration request", Data No. 20 "measured correction target 2 request", and
Data No. 27 "logical correction target 2 request".

*11 The command reads the execution result of the "zero shift request" or "zero shift

reset request" whichever was last issued.

*12 By reading the "system parameter current state," the system parameters of the

sensor amplifier can be checked. The system parameters are comprised of the
settings of "judgment output/check output" polarity and analog output.
The "system parameter" attribute specifies the system parameters which are set
when the "system parameter set request" is executed by a motion command.
The values to be read or written are specified by translating them to binaries and
using ON or OFF in each bit of the binaries.

Assume the read data is "006":
Translating "6" to a binary number gives "0110".

Thus, the sensor amplifier from which the data was read is set to "NPN
output" and "analog output 1 to 5 V".
