Premium and Advantys STB on Profibus DP.doc – Juni-05
Schneider Electric 39
Functional
expansion
Advantys STB supports the local connection of a visual display unit, e.g., a Magelis
XBT-N 401. In this case, the VDU data must also be transferred between Advantys STB
and the PLC so that the drives can be operated via the local visual display unit with the
aid of the PLC.
Local control/operation of the drives is not possible without a higher level control
system. This is mainly attributable to the state machine required for control of the
variable speed drive, which is only available on the PLC and cannot be implemented
locally.
Operating behavior
Starting
characteristics
• As soon as the power is switched on, the drive island devices enter the initialization
phase, during which their own parameters are (re)set. The Advantys STB
initialization process is the longest. During this time, the CANopen extension starts
up and parameters are transferred from the Advantys STB to the extension devices
(if such parameters have been defined in the Advantys configuration software).
• For the purpose of operating the drive island, the island (i.e., Advantys STB) and the
PLC must be able to communicate with one another. Without this active
communication, it will not be possible for the DriveCom profile of the variable speed
drives to be evaluated and controlled and they will switch to fault mode.
Number of
stations on
the CANopen
extension
• The maximum number of stations on the extension is 12. The configuration
described above is capable of handling six devices without any discernible
problems. Similarly, there is no evidence to suggest that the order/address of the
individual stations will be adversely affected.
• The maximum number of ATV31s on the extension, which is unrelated to the
maximum number of stations, is limited to seven.
Configuring
the ATV31s
As the ATV31s can be configured using the Advantys software as well as the
PowerSuite software or the control buttons on the device itself, the user must take a firm
decision as to which of these configuration options he wishes to adopt:
Advantys: If configured using Advantys, the ATV31 receives the
values configured in Advantys every time
the extension is restarted, e.g., when the island
is restarted.
PowerSuite/control keys: If the parameters are modified using PowerSuite or the
control keys, the changes are immediate and
will be retained even if the ATV31 is restarted,
provided that no parameters have been modified
with the Advantys software.
