Note 1. The unit number specified by the instance ID must be set between 0001
Hex and 0010 Hex.
2. An error will occur if the unit number of an E39-TM1 Terminal Block Unit is
specified.
3. When WRITE commands are executed, the settings are written to the in-
ternal memory. The number of times that data can be written to the internal
memory is limited. The internal memory may be corrupted if more than one
million (1,000,000) write operations are performed for each Sensor and pa-
rameter. Therefore, when using WRITE commands, be sure to create a
communications program that prevents the number of writing operations
from exceeding one million (1,000,000) for each Sensor and parameter.
4. Do not send commands for attribute ID that are not specified. Accidentally
sending such commands may overwrite internal parameters. If the internal
parameters of a connected Sensor are overwritten, execute the Initialize
Sensor Settings operation command. If the internal parameters of the Fi-
ber Amplifier Sensor Communication Unit are overwritten, write 0000 Hex
for the following attribute ID settings to clear them.

The following explanations provide the data format for each item.
Writes the threshold setting of the Sensor for the unit number specified in the
instance ID to the Sensor's internal memory. The data is given as a 2-byte (4-
digit) hexadecimal value, and negative data is expressed as its two's comple-
ment.
Note 1. The Write Threshold Setting command cannot be executed when the Zero
Reset setting is enabled. Disable Zero Reset to execute the Write Thresh-
old Setting command.
2. The setting range of Write Threshold Setting command changes when the
Write Hysteresis Width command is executed. An error will occur if the val-
ue written is outside the setting range.
Sets the basic settings of the Sensor for the unit number specified in the
instance ID. The data contents is shown in the following table.
