MOVI-PLC® advanced DH.41B controller
Introduction
System buses
CAN 1, CAN 2 and
Ethernet 1
You can use the MOVI-PLC
®
advanced
DH.41B controller to control a machine module
by coupling several inverters via the system bus. In this way, MOVI-PLC
®
advanced
DH.41B controls all the drives within the machine module and in doing so takes off load
from the master controller (e.g. machine or system PLC). You can connect a maximum
of
64
of the following units to the MOVI-PLC
®
advanced
DH.41B controller via system
buses CAN 1, CAN 2 and Ethernet 1:
• MOVITRAC
®
B frequency inverter
• MOVIDRIVE
®
MDX60B/61B drive inverter
• MOVIAXIS
®
servo inverter
• Gearmotor with integrated frequency inverter MOVIMOT
®
(Fieldbus interface
DeviceNet MFD... required)
Configuring the
PROFIBUS
interface
The PROFIBUS station address is set using the DIP switches on the front of the
MOVI-PLC
®
advanced
DH.41B controller. This manual setting means the MOVI-PLC
®
advanced
DH.41B controller can be integrated into the PROFIBUS environment and
switched on within a very short period of time. The higher-level PROFIBUS master can
set the parameters automatically (parameter download).
This option offers the following advantages:
• Less time required to start up the system
• Simple documentation of the application program as all important parameter data
can be transferred from the program of the higher-level controller.
Cyclical and acycli-
cal data exchange
via PROFIBUS DP
While process data is usually exchanged cyclically, drive parameters are read or written
acyclically using functions such as
Read
and
Write
or via the MOVILINK
®
parameter
channel. This parameter data exchange enables you to implement applications in which
all the important drive parameters are stored in the master programmable controller, so
that there is no need to make parameter settings manually on the inverter itself.
Cyclical and acycli-
cal data exchange
via PROFIBUS
DP-V1
The PROFIBUS DP-V1 specification introduced new acyclical
Read
/
Write
services with-
in the context of the PROFIBUS DP-V1 expansions. These acyclical services are insert-
ed in special telegrams during cyclical bus operation to ensure compatibility between
PROFIBUS DP (version 0) and PROFIBUS DP-V1 (version 1).
PROFIBUS moni-
toring functions
Using a fieldbus system requires additional monitoring functions for the drive technolo-
gy, for example, time monitoring of the fieldbus (PROFIBUS timeout). The function mod-
ule that addresses the PROFIBUS issues a PROFIBUS timeout using the relevant fault
information. This allows the application to respond to the PROFIBUS timeout.
