Note 1. Sequences with interrupt notification are not supported by the CS1W-SCU@@(-V1) and CJ1W-
SCU@@(-V1) Serial Communications Units. A protocol syntax error will occur if an attempt is made
to execute either sequence with a Serial Communications Unit.
Do not set an EM bank as the receive storage word for interrupt notification. A protocol syntax error
will occur if an EM banks is set.

name
Starts a continuous measurement.
The interrupt notification method is
used for receive data.
Terminates continuous measurement.
Requests measurement data in the
idle measurement status or the latch
data generated by the measurement
command.
Sets the forced zero direction to posi-
tive (+).
Sets the forced zero direction to neg-
ative (–).
Releases the forced zero direction.
Clears the 3Z4L, sets the mm unit,
and clears the memory unit settings.
Used to send data of a specified data
length, and receive only OK as the
receive data.
Used to send data of a specified data
length, and receive data other than
OK.
Sets the Laser Micrometer's high cali-
bration.
Sets the Laser Micrometer's low cali-
bration.
Set the constant 0000 for the 3rd operand (S).
Set the constant 0000 for the 4th operand (D).
