address 5.
YM2,W-M,101,105,5,40003,INT16
Description • You can execute this command on models
with the /C2 or /C3 serial interface option.
• You can use this command when the serial
interface protocol is set to Master. For serial
interface settings, see section 2.3.
• The settings specified with this command take
effect when you save the settings with the XE
command and power-cycle the MV.

into Modbus registers
Syntax YM p1,p2,p3,p4,p5,p6,p7
p1 Command number (1 to 16)
p2 Command type
W Write data from measurement
channels
W-M Write data from computation
channels
p3 First channel number
Measurement channel number (1 to 48) if
p2 is set to W
Computation channel number (101 to 124) if
p2 is set to W-M
p4 Last channel number (1 to 48)
Measurement channel number (1 to 48) if
p2 is set to W
Computation channel number (101 to 124) if
p2 is set to W-M
p5 Server number (1 to 16)
p6 First register number (40001 to 499991,
400001 to 465536)

Store or discard the settings (STORE,
ABORT)
Example Save the setup data of the basic setting
commands.
XESTORE
Description To activate the settings that are changed with
the basic setting commands, you must save the
settings with the XE command. Make sure to
save the settings with the XE command before
changing from Basic Setting Mode to Operation
Mode. Otherwise, new settings will not take
effect.
