Connecting a Hand Held Terminal
Because the HART protocol supports up to two digital communication
masters at one time, you can use a hand-held terminal to communicate with
the HART field devices without disrupting their connection to the Terminal
Blocks.
To do this, attach the clips of your hand held terminal to either end of the
resistor on the Terminal Block that corresponds to the channel to which
you wish to connect. (See Figure 2.14.)
F igure 2.15 and Figure 2.16 show
the channels and their corresponding resistors.
