Yokogawa Standalone MW100 - Manual (Page 43)

1-36 IM MW100-17E
Example Set command number to 003, command to valid,
command type to READ, server number to 1, register
address to 30001, data type to INT16, first channel to
C001, last channel to C005, and unit number to 1.
WF003,ON,READ,1,30001,INT16,C001,C005,1
Explanation • You can set this command on products with the /M1
MATH function option.
• When p3 is READ, p7 and p8 can only be set to
C001 to C003.
• p7 and p8 can only be set to the same type of
channel.
• If the data type is INT16 or UNIT16, the maximum
number of channels that can be set from first to last
channel is 127. For other data types, the maximum
is 63.
• Command to specify the unit number
Firmware version R3.03 or earlier: WE
Firmware version R3.04 or later: WF
See the note below.
Note
The "Unit number" parameter of the WE command under the
firmware version R3.03 has been changed to the WF command
under firmware version R3.04. If settings files are loaded that are
of older or newer version than the firmware version, any extra or
missing parameters will be ignored or added when the settings
are interpreted. For example, users not connected to Modbus
Gateway (users using unit number 255) can obtain the same
operational result even if they load settings files of older or newer
versions. However, users connected to Modbus Gateway (users
using unit numbers other than 255) will have to manually reenter
the unit numbers after loading the settings file.
