Fig. 51 CAN bus interface -1- in combination with
RS-232 REAR interface -2-.
Installation of the interfaces
The interface is built into the rear side of the device. It can be already
installed in a device on delivery.
Only Regatron can retrofit this interface.
Combination with other interfaces
The interface is always supplied in combination with the RS-232
REAR interface.
The RS-232 REAR interface takes over the tasks of the RS-232
interface on the front side of the device.
An active CAN/CANOpen® interface has a higher priority than
HMI/RCU control units connected and therefore implements its
commands instead.
Technical characteristics
Type of bus connection: plug, D-Sub 9-pin
CANOpen protocol: CiA standard 301 V 4.02
Function
Unlike the internal CAN bus in the device, which is responsible for the
internal flow of information in the device and that is supplied as standard,
the optional CAN/CanOpen® interface is used for the connection of
devices from other manufacturers.
As a real-time system the CAN bus can be used for controlled systems.
The CAN bus is a serial two-wire bus that combines a high transmission
speed with the communication protocol CANOpen®. By means of its
collision management a lasting communication blockage on the bus is
prevented.
The utilisation of the CAN/CANOpen® interface makes it possible to
connect the TopCon power supply to a type of communication network
in widespread use in industry.
You will find further information in the instructions supplied with the order.
