The HE693PBM101 functions as a Profibus DP network master and is capable of controlling up to 64 slave devices.
The Profibus DP application allows for the connection of I/O devices and simple field devices to an automation system via a Profibus network. Emphasis is on the fast transmission of small data volumes.
The PBM101/ PBM101-12 operates as Profibus DP module only and does not support other types of Profibus (FMS, PA).Profibus uses a Master-Slave type of communication with the HE693PBM101 functioning as the master device.
The HE693PBM101 communicates with slave devices such as input/output devices, drives, valves, and measuring transmitters via a Profibus network.
when used with HE Profibus Slave Modules it allows communication between modules located in different PLC racks via the Profibus network.
