Rewriting a setting value of a sensor amplifier
Available setting values: HIGH setting value (Bank0, Bank1), LOW setting value
(Bank0, Bank1), and zero shift setting value (Bank0)
Device assignments: "Rewrite setting value" (page 3-13)
The setting value to be rewritten is the values listed above. In case of
rewriting the setting value of a BANK number other than the values
listed above, see "Reading/Writing Settings or Status of a Sensor
Amplifier" (page 3-23).
When rewriting any setting or parameter other than listed above, use the
procedure described in "Reading/Writing Settings or Status of a Sensor
Amplifier" (page 3-23).
This example changes the HIGH setting value of ID01.
It assumes that the operating mode assigned to the device is 3-output mode.
(1) Write the new setting value in the "setting-value rewrite data." For details of writ-
able ranges, see "Command parameter list for IB series" (page 3-28).
(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) If an error occurs during "setting value rewriting" on the sensor amplifier, the "set-
ting value rewrite error" signal flips from 0 to 1. (The output is an OR sum of set-
tings.) Check the value entered in the "setting-value rewrite data."
(5) When the "request to rewrite setting value" command is set to 0, the "setting value
rewrite complete" and "setting value rewrite error" parameters flip to 0.
