OVERVIEW
The Plant Loop to Plant Loop Remote Interface (INPPR01)
enables communication between a local and remote Plant
Loop. Two modes (user-selectable) of control are available. A
local Plant Loop is able to issue control commands and receive
Exception Report (XR) data from up to 32 remote Plant Loops
when it is in the one-way mode. Only the local Plant Loop can
initiate control commands and request exception reports in the
one-way mode. The two-way mode connects only two Plant
Loops. In the two-way mode, either Plant Loop is able to initiate
control commands and request exception reports. Plant Loop
to Plant Loop Remote Interfaces can connect through cable,
modem or microwave link. Figure
shows a block diagram of
Plant Loop to Plant Loop Remote Interfaces in two-way control.
The INPPR01 is a direct replacement of the Network 90 Plant
Loop to Plant Loop Gateway (NPPG02).
INTENDED USER
System engineers and technicians should read this manual
before installing and operating the INPPR01 module. Refer to
the
