Introduction
Communication
interfaces
The DHP11B control card is equipped with numerous communication interfaces.
The two system bus interfaces CAN 1 and CAN 2 are used primarily for connection.
They serve for controlling several drive inverters and for integrating decentralized I/O
modules. This module can be operated via a PROFIBUS slave interface with a higher-
level controller.
The RS485 interface is used as an engineering interface, to connect terminals or to con-
trol other frequency inverters.
Automation
topology
Use as a standalone machine controller
You can use the DHP11B control card as the control unit for a complete machine.
When no master PLC is used, the DHP11B control card takes over all control tasks. This
means that the DHP11B controls drives and other actuators and evaluates decentral-
ized inputs and outputs.
In this type of standalone topology, operator terminals (DOP11A) function as the inter-
face between the operator and machine (HMI functions). The operator terminals
(DOP11A) come equipped with an integrated web server and act as an interface to the
company’s Ethernet network.
