    Switching on the operating voltage

    Please notePlease observe also the switching-on instructions in themanual for your PLC controller.

    When the controller is switched on, it automatically carriesout a comparison between the NOMINAL and the ACTUALconfigurations. For this configuration run it is important that:

    the specifications for the field bus configuration are com-plete and correct.

    the power supplies for the PLC and the field bus slavesare switched on either simultaneously or in the sequencespecified below.

    Please note the following points when switching on the powersupply:

    Commonsupply

    If there is a common power supply for the control systemand all the field bus slaves, the power should be switchedon via a central power unit or switch.

    Separatesupply

    If the control system and the field bus slaves have separatepower supplies, the power should be switched on in thefollowing sequence:

    1. the power supply for all the field bus slaves

    2. the power supply for the controller.

    FREEZE and SYNC

    The operating modes FREEZE and SYNC are supported by theFesto Local control unit in accordance with EN 50170 (DIN19245). The use of the FREEZE or SYNC command dependson your master controller. Please refer to the documentationfor your field bus module for further information.

    CautionIn the following cases, the FREEZE or SYNC mode will beautomatically reset:

    when the Local control unit is switched on/off

    when the field bus module has stopped

    The FREEZE mode will also be automatically reset in thefollowing case:

    when the bus connection to the Local control unit is in-terrupted (response monitoring active).

    FREEZE With this function all the inputs of the Local control unit canbe frozen. The Local control unit then sends a constantinput image of all the inputs to the master. The followingFREEZE command causes the input image to be updated.The updated input image is then sent constantly to themaster.Return to normal operation with the UNFREEZE command.

    With the following faults, the reaction of the Local control unitdepends on the configured reaction of the master module.

    Telegram failure

    Master has stopped

    Interruption in bus cable

    If setting or configuration is successful, all the outputs (valvesor outputs) will be switched off or maintain their status.

    WarningS Make sure that valves and outputs are reset when thefaults mentioned occur.

    A dangerous situation can arise if the valves and outputsare not reset.

    5.3.1 General DP master

    With the function Set_Prm you have the possibility of deter-mining the watchdog time (WD_Fact_1, Octet 2, WD_Fact_2,Octet 3). In the event of a fault, e.g. a bus failure, the Localcontrol unit will switch off all the valves and electric outputsafter the parametrized time.

    5.3.2 Siemens SIMATIC S5/S7

    With these controllers you can determine the reaction of theLocal control unit to the faults mentioned (details see con-troller manual).

    Almost all configuration programs contain the function Re-sponse monitoring. For the operating modes mentioned, thetime specified corresponds to the drop-off time of the valvesand electric outputs.Further details on response monitoring can be found in theappropriate manuals.

    You can set two types of error reactions of the control system.

    S when a fault occurs the controller switches to the operat-ing mode STOP (hard error reaction) or

    S when a fault occurs the controller remains in the operat-ing mode RUN (soft error reaction)
