The CBP2 (Communication Board PROFIBUS) serves to link drives and higher-level automation
systems via the PROFIBUS-DP. For the purpose of PROFIBUS, it is necessary to distinguish
between master and slave converters.
Masters control the data traffic via the bus and are also referred to as active nodes . There
are two classes of master:
DP masters of class 1 (DPM1) are central stations (e.g. SIMATIC S5, SIMATIC S7 or
SIMADYN D) which exchange data with slaves in predefined message cycles.
DPM1s support both a cyclic channel (transmission of process data and parameter data)
and an acyclic channel (transmission of parameter data and diagnostic data).
DP masters of class 2 (DPM2) are programming, configuring or operator
control/visualization devices (e.g. DriveMonitor) which are used in operation to configure,
start up or monitor the installation.
DPM2s support only an acyclic channel for transferring parameter data.
The contents of the data frames transferred via these channels are identical to the structure
of the parameter section (PKW) as defined by the USS specification.
7-28
section of the telegram (required only if the PPO type cannot be set via PROFIBUS-
DP master)
The DP master configuring data determine whether the slave (CBP2) must monitor
telegram traffic with the master. If this monitoring function is activated, the DP master
passes a time value (watchdog time) to the slave when the link is set up. If no data
are exchanged within this period, the slave terminates the process data exchange
with the SIMOTRAS HD converter. The latter can monitor the process data as a
function of U722 and activate fault message F082.
