2. Do not send commands that are not specified for variable types. Acciden-
tally sending such commands may cause internal parameters to be over-
written. If the internal parameters of a connected Sensor are overwritten,
execute the Initialize Sensor Settings operation command.
Number of Elements
Specifies as hexadecimal ASCII the number of Units after the specified unit
number that are to be written. The leftmost bit is set to 1. Therefore, the num-
ber of elements is set to "8001" to write one Unit. The number of elements for
writing parameters can be set to "8001" only.
Write Data
Gives the write data in hexadecimal ASCII.
The following information describes the data format for each item.
Writes as a 4-digit hexadecimal value the number of registered Sensors to the
internal memory. The number of registered Sensors that is written to the inter-
nal memory is enabled when DIP switch pin 3 is ON. If a write operation is
attempted when pin 3 is OFF, an error will occur. The data setting range is
"0001" to "0010" (1 to 16 Units), and the default setting is 16 Units.
The Communication Unit's response delay time (time for a CompoWay/F
response to be returned) is set as a 4-digit hexadecimal value. The unit is ms
and the data setting range is "0000" to "0064" (0 to 100 ms). The default set-
ting is 0 ms.
Some CompoWay/F masters, such as CQM1H Serial Communications
Boards, cannot read responses that are returned too quickly. If using this type
of master, set a response delay time (time taken by the Communication Unit
to return a response). The default setting is 0 ms.
Writes the threshold value to the Sensor's internal memory as 4-digit hexa-
decimal value. Negative data is expressed as its two's complement.
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 a value
is written outside the setting range.
