  • Page 5: General Description

    E-T-A provides the ideal solution for machine and panel builders with the intelligent protection system comprising the REX12D circuit protector and the EM12D interface module. The system combines the well-proven quality of DC24V overcurrent protection with the communication capabilities to superordinate bus systems.

  • Page 6: Design Of The Entire System

    EM12D-TMB LINE + 1 fig. 1: System overview The Modbus controller EM12D-TMB is the centre of the ControlPlex ® system. It collects all information of the REX12D electronic circuit protectors and forwards it to the superordinate Modbus server and thus to the superordinate control unit.

    Device ID of the unit revision index of firmware fig. 6: Marking of date code 5 Operating modes of the Device EM12D-TMB 5.1 Operating mode: (system start) The Modbus controller is initialised by applying the supply voltage. The device will carry out implemented programme memory tests and self test routines.

  • Page 10: Operating Mode: (Independent Operation)

    5.4 Operating mode: (independent operation) If no connection to the superordinate control unit is recognised after the supply voltage was applied, the module will change into the operating mode “independent operation”. The circuit protectors will adopt the condition specified by the configuration. If there is a connection between the Modbus controller and the superordinate control unit and there is no critical failure, the operating mode “independent operation”...

    The cycle time via the ELBus is 530ms. During the aforementioned period the status and the load current of ® each circuit protector is cyclically transmitted to Controller EM12D-TMB. fig. 9: Cycle times of the system 6.2 Hot swap of circuit protectors The electronic circuit protector REX12D can at any time be mounted side by side with a supply module or an existing system.

  • Page 12: Communication Via Modbus Rtu

    7 Communication via Modbus RTU controller model 7.1 ControlPlex ® The EM12D-TMB has an internal ELBus interface enabling the communication with the electronic circuit ® protector REX12D. Up to 16 channels of the REX12D electronic circuit protectors (single channeled, multi- channeled or a mixed population) can be connected to the supply module.

  • Page 13: Error With Faulty Population

    7.1.1 Error with faulty population If a double channel device is connected as channel 16/17, the control unit will receive the information that a device is available at channel 16. When reading out the Cominfo of the circuit protector, received the message that the circuit protector has wrong parameters.
