Introduction of Features
PROFIBUS-DP
PROFIBUS is an open field bus standard (IEC61158) used in various applications for
factory automation and process automation.
PROFIBUS-DP(DecentralizedPeriphery)isusedforcommunicationbetweenPLCsand
remoteI/O,enablinghigh-speeddatatransmission.
Configuration Components
PROFIBUS-DPnetworkconsistsoffollowingcomponents:
• Class 1 master
 Acontrollertoexchangeinformationwiththeslaveinacyclicmanner.ThisisaPLCor
PC.
• Class 2 master
 Engineering and configuration devices.This is either a PC on which configuration
softwarehasbeeninstalledorsoftwareitself.
• Slave
 I/Odevicesaccessedbythemaster.ThisincludesI/Odevices,sensors,oractuaters.
TheDXisaslavedevice.
• Terminator
 Theterminatorofthebus.
• Cable
 Adedicatedtwo-wirecableisused.
• Others
Repeater, coupler, and other components are also used if needed.
Node
127nodescanbeconnectedtothenetwork.
Note
FordetailsofPROFIBUSspecificationsandinformation,seethedocumentspublishedfromthe
PROFIBUSOrganizationinrespectiveregions.

What the DX Can Do
TheDXprovidesthefollowingfunctions:
• ParticipateinanPROFIBUS-DPnetworkasaPROFIBUS-DPslave.
• Communicate with a PLC from Siemens.
• The master can access internal data of the DX.
Data Access
Measurement channel data Read
Computation channel*1 data Read
Communication input data*1*2 Write
*1 This is an option (/M1 and /PM1).
*2 Communication input data, if coded in a calculation expression in the computation channel,
canbedisplayedontheDX.
The following shows examples of usage.
• DataondevicesonanetworkcanberecordedbyaPLCtotheDX.
• DatameasuredbytheDXcanbeacquiredbyaPLC.
Settings of the DX
TheDXisreadytouseafterthenodeaddresssettingshavebeenmade.
Access to the DX
TheDXisapassivedeviceonanPROFIBUS-DP.TheDXcannotinitiatearequest.PLC,
aclass1masterdevice,initiatesarequestandaccessestheDX.
