INTRODUCTION
The
FRI303 is a Profibus-PA device that has two built-in relays making integration of Profibus-PA to
conventional devices such as solenoids, on/off valves, electrical actuators, motors, pumps, starters,
etc. The FRI303 also has two dry contact inputs. The FRI303 Profibus-PA Remote I/O can be
located in the field, mounted close to the conventional devices without the need to run the
conventional wiring to the control room. The
FRI303
is an integral part of SYSTEM302 but also
integrates into other systems that support Profibus-PA.
The FRI303 allows that conventional discrete outputs be available, in order to make the control
strategy configuration easy. Using standard Profibus-PA Function blocks, these outputs appear as
regular Profibus-PA devices, thus making the system homogenous. Control loops are implemented
consistently.
Function blocks for input and output are available for
FRI303
and provide great flexibility in the
control strategy. The FRI303 is fully configured from SYSTEM302 or any other Profibus-PA
configuration tool.
The FRI303 may be installed close to the discrete devices, thereby eliminating long wire runs,
associated marshaling panels and cable trays for the conventional output. With subsequent savings
further reducing overall system costs. The use of FRI303 makes it possible to distribute outputs at
various locations in the field and connect them via the Profibus-PA.
Get the best result of the FRI303 by carefully reading these instructions.
NOTE
In case of using Simatic PDM as the configuration and parameterization tool, Smar
recommends that the user does not apply the option "Download to Device". This function
can improperly configure the field device. Smar recommends that user make the use of the
option "Download to PG / PC" and then selecting the Device Menu, use the menus of the
transducer, function and display blocks acting specifically, according to each menu and
method for reading and writing.
