INTRODUCTION
FEATURES

FEATURES
The Plant Loop to Computer Interface provides communication
between a host computer and INFI 90 Plant Loop. The modular
design of the interface modules, as with all INFI 90 modules,
allows for flexibility when creating a process management sys-
tem strategy.
The PCI gives the user up to 5,000 point definitions. The LIM/
BTM pair provides data security and integrity through
on-board diagnostics, module time checks and handshaking.
Interface firmware combined with PCT microprocessor based
hardware makes this interface a powerful control tool that the
user can configure for almost any application.
