Profibus module
Parameter Description Possible settings Factory setting
3-12-1-3 Cycle time, setpoint/control value
Time delay before the message (warning or
alert) is triggered. In a redundant system, only
a warning is output as the auxiliary master can
assume the function. Only if the setpoint/
control value also fails at the auxiliary master is
the alert output, which then triggers the
specified response to setpoint/control value
failure.
0.0...10.0 5
3-12-1-4 Cycle time, actual value
Time delay before the message (warning or
alert) is triggered. In a redundant system, only
a warning is output as the auxiliary master can
assume the function. Only if the actual value
also fails at the auxiliary master is the alert
output, which then triggers the specified
response to actual value failure.
0.0...10.0 1
NOTE
If the field bus is only used for monitoring purposes, the Control Point parameter
(3-6-2) is set to Local.
NOTE
If the cycle times of parameters 3-12-1-3 and 3-12-1-4 are set to 0 seconds, the
monitoring function for each of these parameters is disabled.
1.7 Frequency inverter operation with Profibus module
The function and the commissioning procedure described below for the frequency
inverter are based on the device profile and communication profile "Profile for
Intelligent Pumps Version 1.0 November 2007" (PIP), edition for centrifugal pumps
("Rotodynamic pump"), issued by the Profibus user organisation (PNO).
Profibus for PumpDrive 2 is defined as a DP Slave of device type "Drive" and can be
addressed by a class 1 or class 2 DP Master.
The Profibus implementation supports the cyclic exchange of I/O data as part of the
MS0 communication relationship and the acyclic services Read/Write (PI function
blocks RDREC and WRREC) as part of the MS1 communication relationship.
