Available setting values: Instantaneous flow rate setting 1 (P1), instantaneous flow
rate setting 2 (P2), temperature upper limit setting, temperature lower limit setting,
and integrated flow quantity setting 1
When rewriting any settings other than listed above, use the procedure
described in "Reading/Writing Settings or Status of a Sensor Amplifier"
(page 3-21).
This example rewrites the setting value (instantaneous flow rate setting 1) of ID01.
(1) Write the new setting value in the "setting-value rewrite data. For details of writable ranges, see
"Command Parameter List" (page 3-24).
(2) Execute the "request to rewrite setting value" command (0 -> 1).
(3) After the setting value is rewritten, the "setting value rewrite complete" signal flips from 0 to 1.
(4) When the "request to rewrite setting value" command is set to 0, the "setting value rewrite complete"
parameter flips to 0.
(5) If an error occurs while rewriting the setting value on a sensor amplifier of any ID number, the "setting
value rewrite error" signal flips from 0 to 1 (the output is the logical disjunction (OR) for IDs 01 to 10).
Check the value entered in the "setting-value rewrite data."
(6) To clear the setting-value rewrite error, set the "clear setting-value rewrite error" parameter to 1.
Available settings and status: See "Common Command Parameter List" (page
3-24) and "Setting/status command parameters" (page 3-26).
To read/write the settings or status of a sensor amplifier, create a program that
controls commands by handshaking between a remote input/output and remote
register
