Reading Data into External Input Channels (MV2000 only)
The MV reads the data from the server device and enters the data into external input
channels in 16-bit signed integer format.
• Example 1
Read a 16-bit unsigned integer value from instrument C’s register 30001 into external
input channel 201.
30001
201
16-bit unsigned integer
External input channel
Instrument C register
Command
R 201 - 201 3 30001 UINT16
• Example 2
Read a 32-bit unsigned integer value from instrument C’s register 32001 and 32002
into external input channel 202. Specify the smaller register number in the command.

Writing Measured Values to a Server
• Example
Write the measured value of channel 1 (16-bit signed integer) to instrument A’s
register 40001.

Writing Computed Values to a Server
• Example
Write the computed value of channel 101 (32-bit signed integer) to instrument A’s
40001 and 40002 registers, lower 16 bits first and then higher 16 bits. Specify the
smaller register number in the command.
