*7

This is 999.8 when the humidity is not acquired correctly.

*8

If a prohibited combination of functions is written, it results in "abnormal setting

(1)." For details of each function, refer to the

SK-1000 Series User's Manual.

*9

The "initial reset request" motion command result is included in this item.
Regarding data category N x 10 + 1 Data No. 79 (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 prog-
ress" 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 category N Data No. 69 "initial reset" request. A "1: success-
fully completed" result then occurs if all parameters have been saved to the non-
volatile memory (EEPROM) approximately 3 seconds later.

-

When "zero shift status save" is ON, writing begins immediately for data cat-
egory N Data No. 65 "zero shift request" and Data No. 66 "zero shift reset
request".

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

reset request" whichever was last issued.

*11 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".

*12 This parameter works if "Bank switching method" is set to "button."
*13 These parameters are OFF only if data "0" is written and the wiring is configured

to turn off external input.

*14 A write control error results if data is rewritten to an expansion unit.
