Summary of Contents for SMAR FRI303

  • Page 3 Introduction 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.

  • Page 7: Section 1 - Installation

    Installation close to lines and vessels subjected to high temperatures also should be avoided. The use of sunshades or heat shields to protect the FRI303 from external heat sources should be considered, when necessary. Humidity can be fatal to electronic circuits. A humidity proof coating protects the electronic circuit, but frequent exposures to humidity may affect the protection provided.

  • Page 17: Section 2 - Operation

    Section 2 OPERATION The FRI303 has 2 isolated built-in relay outputs and two dry contact inputs. It is therefore ideal for interfacing existing discrete devices to a Profibus-PA system. Output function blocks include standard Profibus-PA safety mechanisms in case of failures. Outputs are isolated from each other.

    CONFIGURATION One of the many advantages of Profibus-PA is that device configuration is independent of the configuration tool. The FRI303 may be configured by a third party host computer using the EDDL (Device Description) or FDT/DTM tools. The FRI303 has 02 DIs (Discrete Input) and 02 DOs (Discrete Output) blocks.

    Smar devices can be purchased via internet in www.smar.com. See below a typical example with the necessary steps to the integration of a FRI303 device in a PA system and that can be extended for any device: Copy the GSD file of the device for the search directory of the PROFIBUS configurator, usually named GSD.
  • Page 23 The watchdog condition can also be activate, where after the communication loss detection for the slave device with the master, the equipment can change to a fail-safe condition. The FRI303 also has the Empty module for application where is not necessary all function blocks. There is an order for cyclic communication as follow: DO_1, DO_2, DI_, DI_2.

  • Page 24: Cyclical Diagnosis

    FRI303 – Operation and Maintenance, Instruction Manual Cyclical Diagnosis Via cyclic communication is possible to verify diagnostics from the FRI303 using the Profibus Master Class 1 or even via acyclic communication via Master Class 2. The Profibus-PA devices provide up to 4 bytes standard diagnoses via Physcial Block (See figure 3.6.

If the equipment is in "Profile Specific" and using the GSD file Identifier Number equals 0x0dcb, the acyclic communication will work well with tools based on EDDL, FDT/DTM, but no cyclic communication with the Profibus-DP master will get success.
