Functional Description

8/67 ekr 500 digital Unit Touch – CANopen User Gateway

No additional devices are required for the communication between

the web guiding controller and the customer control system.

During commissioning, only the following procedures must be

carried out:

■ Configuration of the integrated CAN bus interface (connector

socket X101) of the ekr 500 digital Unit Touch web guiding

controller as external CAN bus

■ Setting of the baud rate (default setting = 500kBit)

■ Selection of the communication protocol to be used

■ Loading of the provided EDS file into the customer control

system

2.2 CANopen Communication Profile

Communication of the ekr 500 digital Unit Touch web guiding con-

troller with the customer control system takes place via the CAN

bus based on the CANopen communication protocol that is stand-

ardized as the European Standard EN 50325-4.

This chapter describes the basic services and communication

objects of the CANopen DS301 communication profile, which are

used by the ekr 500 digital Unit Touch web guiding controller.

The description of the CANopen communication profile

assumes that the basic functioning of the DS301 commu-

nication profile is known and available as reference docu-

mentation.

2.2.1 Fundamentals

CANopen is an open CAN-based fieldbus standard enabling the

communication of devices of different manufacturers without any

special interface adjustments. The CANopen standard describes

the exchange of data in a CAN-based network. The DS301 com-

munication profile defines the type of data transmission, the dis-

tribution of the identifiers existing in the CAN bus system as well

as their use for the communication services required in a fieldbus

system.
