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
