PROFIBUS DP
PROFIBUS bus system with the DP protocol (decentralized peripherals). The
main task of PROFIBUS DP is fast cyclic data exchange between the central
DP master and the I/O devices.
PROFIBUS DPV1
PROFIBUS DPV1 is an extension of the DP protocol. It enables acyclic data
exchange of parameter, diagnostic, receive and test data.
DP master
A master is designated as a DP master if it works with the DP protocol
according to the EN 50 170 standard, Volume 2, PROFIBUS.
Class 1 master
A class 1 master is an active station on the PROFIBUS DP. The cyclic data
exchange with other stations is characteristic for this type of master. Typical
class 1 masters are, for example, PLCs with a PROFIBUS DP connection.
Class 2 master
A class 2 master is an optional station on the PROFIBUS DP.
Typical class 2 masters are, for example:
• PC/programming devices with the SIMOCODE ES software
• SIMATIC PDM (PCS7)
• PC with SIMATIC powercontrol software (power management).
DPV1 slave
A slave is designated as a DPV1 slave if it is operated on the PROFIBUS bus
with the PROFIBUS DP protocol and works according to the EN 50 170
standard, Volume 2, PROFIBUS.
GSD
Device data (GSD) include DP slave descriptions in a uniform format. Using
GSD (device data) makes it easier to parameterize the DP slaves in a DP
master system.
OM SIMOCODE pro
OM SIMOCODE pro (object manager) is used instead of GSD (device data)
to integrate SIMOCODE pro into STEP7.
OM SIMOCODE pro enables the use of SIMOCODE ES (if it is installed) for
parameterization within STEP7.
