  • Page 5: Application

    1. APPLICATION The SM4 module of logic outputs is destined to control simple actuators through assignment of logic states received from the master device through the RS-485 interface. The module can have 8 logic outputs or 4 relay outputs (depending on the execution) and RS-485 and RS-232 interfaces with MODBUS RTU and ASCII transmission protocols.

  • Page 6: Module Set

    Remarks concerning the operator safety: 1. General - The SM4 module is destined to be mounted on a 35 mm mounting rail. - Non-authorized removal of the required housing, inappropriate use, incorrect instal- lation or operation creates the risk of injury to personnel or damage to equipment.
  • Page 7 - The manufacturer of the measuring system or installed devices is responsible for the compliance with the required limit values demanded by the EMC legislation. 5. Operation - Measuring systems including SM4 modules, must be equipped with protection devices according to the corresponding standard and regulations for prevention of accidents.

  • Page 13: Description Of The Modbus Protocol Implementation

    One can program all module parameters by means of RS-232 or RS-485. The RS-232 port has constant transmission parameters in accordance with tech- nical data, what enables the connection with the module, even when programmed parameters of the RS-485 digital output are unknown (address, mode, rate). The RS-485 standard allows to the direct connection to 32 devices on a single serial link up to 1200 m.
