IM MW100-72E
Setup Example
Data is sent and received between the MW100 client and MW100 server. The MW100
client loads and displays measured data from measurement channels 001 to 004 of
the MW100 server, and also writes that data to the MW100 server. The following is an
example in which the data written to the MW100 server is displayed.

Data in the Example
The data that is sent and received in this setting example is as follows.
1. Measured data from measurement channels 001 to 004 of the MW100 server are
written to communication input channels C001 to C004 of the MW100 client as 32-bit
floating point (float) type data.
For READ (client loads data from server)

Input register numbers starting from 31001 are specified
to acquire 32-bit floating point type measured data.
“Float-Little” is selected for the register data type because the 32-bit floating
point type measured data is received in the order lower byte, upper byte.
