iSlaveaddress: slave address

iCounter: 1:PhysicalFaultCounter, 2:TimeoutCounter, 3:ResponseCounter, 4:Leave-DataExchCounter, 5:DataExch-FailedCounter

bCounterReset: resetting of the current counter

bReadLES: list of recognised ASI slaves (LES)

bReadWrite: 0=READ, 1=WRITE

bReadLAS: list of activated ASI slaves (LAS)

bStart: The respective task is carried out via a rising edge at this boolean input

bCycleMode: 0=continuous reading 1= reading once

    bBusy               :BOOL;
    bErr                :BOOL;

END_VAR

bBUSY: This output remains TRUE until the block has executed a command. While Busy = TRUE, no new command will be accepted at the inputs. Please note that it is not the execution of the service but its acceptance whose time is monitored.

bErr: This output shows the error status

iErrornumber: Contains the command-specific error code of the most recently executed command. Is reset to 0 by the execution of an instruction at the inputs.

iCountervalue: counter reading

iSlaveList: LES or LAS
