basic DHP11B.. controller
System buses
CAN 1 and CAN 2 You can use the MOVI-PLC
®
basic DHP11B.. controller to control a machine module by
coupling several inverters via the system bus. The MOVI-PLC
®
basic DHP11B..
controller controls all the drives in the machine module and thereby relieves the higher-
level control (e.g. machine or system PLC) of load. You can connect a maximum of
twelve of the following devices to the MOVI-PLC
®
basic DHP11B.. controller using
system buses CAN 1 and CAN 2, which means a maximum of six per CAN interface:
• MOVITRAC
®
07A or MOVITRAC
®
B frequency inverters
• MOVIDRIVE
®
MDX60B/61B drive inverter
• MOVIAXIS
®
servo booster
• MOVIMOT
®
gearmotors with integrated frequency inverter (CANopen MFO...
fieldbus interface required)
In the case of manual setup of SCOM objects, more than 12 inverters can be controlled
depending on the data to be transferred (
Æ
Sec. 8.1).
Configuring the
PROFIBUS
interface The PROFIBUS station address is set using the DIP switches on the front of the MOVI-
PLC
®
basic DHP11B.. controller. This manual setting means the MOVI-PLC
®
basic
DHP11B.. controller can be integrated into the PROFIBUS environment and switched
on within a very short period of time. The higher-level PROFIBUS master can automat-
ically set the parameters (parameter download).
This option offers the following advantages:
• Less time required to start up the system
• Simple documentation of the application program, since all important parameter data
can be transferred from the program of the higher-level controller.
Cyclical and
acyclical data
exchange via
PROFIBUS-DP While process data exchange usually takes place cyclically, drive parameters are read
or written acyclically via functions such as
read or 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 drive inverter itself.
Cyclical and
acyclical data
exchange via
PROFIBUS-DP-V1 The PROFIBUS-DP-V1 specification introduced new acyclical read/write services as
part of the PROFIBUS-DP 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
monitoring
functions Using a fieldbus system demands additional monitoring functions for the drive tech-
nology, e.g. 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.
RS485 interface
COM1 Connect one of the following devices to the RS485 interface COM1:
• Engineering PC, or
• DOP11A operator terminal
