4.1 Field of application

SIMATIC PN/CAN LINK
Operating Instructions, 03/2022, A5E39895388-AC

General features

•

CAN interface according to ISO 11898-2 (High Speed CAN)

•

2 PROFINET interfaces (integrated switch) enable PROFINET line operation according to

Conformance Class B (CC-B).

•

In addition to the PROFINET and CAN protocol, the PN/CAN LINK also offers the CANopen

protocol. This means the PN/CAN LINK can be operated as a CANopen node and can also

take on the role of CANopen Manager in the CANopen network. The PN/CAN LINK can be

operated in the following three modes:

–

CANopen Manager

–

CANopen Slave

–

CAN transparent

•

The operating mode for the PN/CAN LINK is set via the associated HSP in the TIA Portal.

•

The PN/CAN LINK supports both the standard format (CAN 2.0A) as well as the extended

CAN format (CAN 2.0B).

•

The PN/CAN LINK can operate up to 126 nodes in the CAN network in Manager mode.

•

The CAN side supports baud rates from 50 kBaud up to 1000 kBaud.

•

The maximum permissible cable length of the CAN network is up to 1000 m (dependent

on data transmission rate, cable cross-section, number of nodes).
