MOVI-PLC® advanced DH.41B control card
Introduction
System buses
CAN 1, CAN 2 and
Ethernet 1
You can use MOVI-PLC
®
advanced DH.41B to control a machine module by connecting
several inverters via one system bus. In this way, MOVI-PLC
®
advanced DH.41B con-
trols all the drives within the machine module and thereby takes off load from the higher-
level controller (e.g. machine or system PLC). You can connect up to 64 of the following
units to MOVI-PLC
®
advanced DH.41B via system buses CAN 1, CAN 2 and Ethernet 1:
•MOVITRAC
®
07A or MOVITRAC
®
B frequency inverters
•MOVIDRIVE
®
MDX60B/61B drive inverters
•MOVIAXIS
®
servo drives
• MOVIMOT
®
gearmotors with integrated frequency inverter (DeviceNet MFD...
fieldbus interface required)
Configuration of
the PROFIBUS
interface
The PROFIBUS station address is set using the DIP switches on the front of the
MOVI-PLC
®
advanced DH.41B controller. You can use these manual settings to inte-
grate and switch on the MOVI-PLC
®
advanced DH.41B control card in the PROFIBUS
environment in next to no time. The higher-level PROFIBUS master can set the
parameters automatically (parameter download).
This option offers the following advantages:
• Shorter start up times
• 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 higher-level programmable control-
ler, so that there is no need to make parameter settings manually on the drive 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
inserted 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
technology, for example, time monitoring of the fieldbus (PROFIBUS timeout). The
function module that addresses the PROFIBUS issues a PROFIBUS timeout using the
relevant fault information. This allows the application to respond to the PROFIBUS
timeout.
