  • Page 3: Application

    1. APPLICATION n Module of logic inputs The SM3 module of two logic inputs is destined to collect logic states of logic inputs and make them accessible to computer-based industrial systems working on the base of the RS-485 interface. The module has 2 logic inputs and RS-485 interface with MODBUS RTU and ASCII transmission protocols.

  • Page 5: Basic Requirements, Operational Safety

    Remarks concerning the operator safety: 1. General  The SM3 module is destined to be mounted on a 35 mm rail.  Non-authorized removal of the required housing, inappropriate use, incorrect installation or operation creates the risk of injury to personnel or damage to equipment.
  • Page 6 EMC legislation. 5. Operation  Measuring systems including SM3 modules, must be equipped with protection devices according to the corresponding standard and regulations for preven- tion of accidents. ...

  • Page 7: Installation

     Before taking the instrument housing out, one must turn the supply off. The removal of the instrument housing during the guarantee contract period may cause its cancellation. 4. INSTALLATION 4.1. Module fixing The module is designed to be fixed on a 35 mm rail (EN 60715). The module housing is made of a self-extinguishing plastic.

  • Page 24: Impulse Counter

    6. IMPULSE COUNTERS Each of the converter impulse inputs is equipped with two independent 32-bit counters main and auxiliary impulse counters. The maximal state of counters is 4.294.967.295 (2?? - 1) impulses. The increase of counters by one follows simultaneously at the moment of the de- tection of an active state of suitably long duration on the impulse input and a state opposite to the active state of suitably long duration.

  • Page 25: Configuration Of Impulse Inputs

    7. CONFIGURATION of IMPULSE INPUTS The configuration of device parameters being in registers 7606 7613 (4206 4211) is possible after a previous write of the value 112 to the register 7614 (4212). The write of the value 1 to the register 7605 (4205) causes the activation of impulse inputs and all configuration functions related to the active working mode.

    Shorter impulses from the value set in registers will not be counted. Impulse inputs are sampled in intervals of 0.5 millisecond. 7.3. Input weight The user has the possibility to define the value of the impulse weight (registers 7612, 7613). The result is determined in the following way: ResultMeasurement_Y = CounterValue_X/WeightValue_X ResultMeasurement_Y - Measurement result for the appropriate input and chosen counter...
