    Glossary Baud rate The speed of data transmission, expressed as the number of bits transferred per second (baud rate = bit rate). ET 200 supports baud rates from 9.6 kbaud to 12 Mbaud. Binary file If, after exporting data to a memory card, you wish to save this data on the PG/PC as well, you must create a binary file.

    Glossary DP Siemens The bus protocol developed by Siemens. With the cooperation of the PROFIBUS User Forum, this bus protocol has been extended into an open, vendor-independent system. The extended bus protocol has been submitted to the Deutsche Elektrotechnische Kommission (DKE) and ratified as national draft standard DIN 19245, Part 3 ( DP standard).

    Glossary Grouping On grouped modules, multiple input and output circuits share a common connection. The common connection may carry either the (L-) potential (M-grouping) or the (L+) potential (P-grouping). Group Membership of a bus node to a group. membership Host A host is a system or device containing at least one DP master, for example: The programmable controller with the CPU is the host, the IM 308-C is the DP master.

    Glossary Isolated On an isolated I/O module the reference potentials of control and load circuits are galvanically isolated, e.g. by optocouplers, relay contacts or transformers. Input and output circuits may be grouped. Not to be confused with ”floating”.

    Glossary RS 485 repeater Device for amplifying bus signals and linking segments over large distances. An operating mode of the DP master. The DP master cyclically reads the input data of the DP slaves and sends output data to the DP slaves. The DP master is participating in the token ring. Segment The bus line between two terminating resistors constitutes a segment.

    Glossary Station Device which can send, receive or amplify data on the bus, e.g. DP master, DP slave, RS 485 repeater, star hub. Station number Each station must be assigned a unique station number for identification. The PG or the ET 200 Handheld has the station number ”0”. DP masters and DP slaves are assigned station numbers in the range 1 to 123, with the following exceptions: ET 200B has a station number in the range 1 to 99.
