The Remote I/O Port of the Communications Controller
Programmable Controller Host Communications
Using programmable controller ladder logic to initiate Block Transfer
Writes and Reads (BTW and BTR), data can be sent to and received from
the HART field devices. A host computer on the DH+ network running
application programs (such as ControlView) can read and display the data
which the programmable controller has obtained from the HART field
devices. (See Figure 1.4)
