Address_stage2 consists of a maximum of two characters:
1st. Character: Decentral peripheral device ("0") or drive ("1"). This merely defines the data location within the telegram. The data for a decentral peripheral device is deposited in "Intel Format" (low byte in front of high byte). The data for a drive are deposited according to the PROFIBUS profile Drive Technology (PPO types) in "Motorola Format" (high byte in front of low byte).
2nd. Character: If no specification is made, then the access to the Slave occurs as a parameter setting Master. The specification "R" implies that the access occurs as a read accessing second Master. The specification "R" is only possible for receive channels ("Shared Input").
