LSB Least significant bit
Master Bus participant with independent sending authority. Masters
are hosts, like PLCs or PCs.
Mixed operation Operating mode, when there are PROFIBUS-FMS and DP
masters
Mixed device Device which incorporates functions according to PROFIBUS-
FMS and PROFIBUS-DP. Lenze controllers are mixed devices
on PROFIBUS or so-called Combislaves.
MSAC Communication relation between master and slave, acyclic
MSB Most significant bit
OFC Optical fibre cable
User data For PROFIBUS DP: data which are exchanged in cycles
between control and controller
PO data Process output data
POWx Process output word of PROFIBUS, viewed from the master
(host); i.e. data from the master to the drive. "x" means the
word address (starting with 1).
PC Personal computer
PCD see process data
PDU Process Data Unit. User data length of a PROFIBUS telegram
PI data Process input data
PIWx Process input word of PROFIBUS, viewed from the master
(host); i.e. data from the drive to the master. "x" means the
word address (starting with 1).
PLC Programmable logic controller such as Siemens SIMATIC S5
PROFIBUS Process Field Bus
Communication standard DIN19245, consisting of part 1, part
2, and part 3
PNO PROFIBUS-Nutzerorganisation e.V.
Group for the promotion of PROFIBUS.
PROFIBUS DP Communication standard to DIN 19245
part 1 and part 3 (draft)
DP means "decentral peripherial units"
PROFIBUS-FMS Communication standard to DIN 19245
part 1 and part 2 (FMS protocol)
Profile The word profile is taken from the communication standard
PROFIBUS (DIN 19245) and describes supplementary or
restrictive regulations which are valid within industries or
device groups.
The DRIVECOM User Group has standardized some
important controller functions in the DRIVECOM profile 21.
Using the 2130 interface module, the Lenze controllers
support the DRIVECOM profile.
Process data For example set-values and actual values of controllers, which
must be transmitted in a very short time. These are small
amounts of data (e.g. two words with DRIVECOM and Lenze),
which are transmitted cyclically. For PROFIBUS, these data
are transmitted in the logic process data channel.
