Level Controlled Continous (AbbLConC)ΒΆ

This state machine is a special case of Level Controlled. Only difference is that this function block type is never done, for example a PID which never stops.

Therefore these function blocks have no Done output.

Description of standard inputs and outputs:

  • Enable

    A rising edge (Enable = TRUE) starts the operation, the output Busy goes to TRUE. All other inputs are read and considered continuously.

    A falling edge (Enable = FALSE) aborts the operation.

    During Aborting the Busy is still TRUE. Afterward all outputs are reset.

  • Busy

    Operation is running (while output Error is FALSE)

  • Error

    Operation is stopped with error (while output Busy is FALSE).

    This output is TRUE for at least one cycle or until Enable is set to FALSE.

    The output ErrorID gives more details about the error.
