Profibus is a control bus that provides a common method to connect automation equipment with devices on a single network. This standard communications media is referred to as Profibus and significantly reduces hardwiring costs. Profibus provides specifications for information exchanged between nodes, such as controller data associated with low-level device and configuration parameters individually related to system operations. Profibus allows 32 stations per segment. Segments vary in length depending on the desired transmission speed. The maximum speed is achieved on a segment 100 meters (327 feet) in length. Each of our Profibus DP Slaves represents a single station. Repeaters also count as stations and are used to extend the network to greater distances. Our Profibus modules support baud rates of 9.6Kbaud to 12Mbaud depending on the network length.
There are three Profibus slave products:

1. Power budget limitations restrict the number of modules allowed in the expansion slots of the DL05/06 PLCs. Please consult the power budgeting tables in your manual or catalog for specific calculations.
Upgrading the firmware in all of our Profibus interface modules is done through our free Module Configuration utility called NetEdit3. If you don't already have a copy of the utility, you can use this link to download the latest version of NetEdit3 from our web site.
Once you have NetEdit3 installed on your PC, use the File->Live Update
feature to download the latest version of the firmware files from the Host
Engineering website. Follow the instructions in NetEdit3 to perform the
