iSlaveAddress: Station address.

iPnu: Selection of the parameter to be read or written. List of the available parameter numbers.

nAxis: Axis ID.

iLength: Length of the parameter (2 or 4).

iParameterValue : Value of the parameter to be read or written.

iFC310xDeviceId : Device-Id

bStartRead : A rising edge at this boolean input sends a command to the axis to start reading the parameters selected with "Pnu".

bStartWrite : A rising edge at this boolean input sends a command to the axis to start writing the parameters selected with "Pnu".When changing operating mode, the write command is only effective if Stop = TRUE at the FB_AX2000_AXACT block.

tTimeOut: The maximum timeout - this time must not be exceeded.

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.

iErrorId : 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.

iReadValue : Parameter value as a response to the "StartRead" command.
