3.3.2 CAN interface
The two CAN Controllers are directed via CAN drivers to 9−pole D−Sub plug−in
connectors with standard connector allocation (electrically isolated).
Because theETCPx has only one plug−in connector per CAN channel, the
subassembly must either be connected to one of the two bus ends or it must
be integrated with the bus line using an adapter cable or node connector
(e.g. ERbic by ERNI).
If the ETCPx is positioned at the CAN bus start or end, a terminating resistor
can be added on the board via the jumpbers J7 and J10.
A CAN high−speed interface in accordance with the ISO/DIS 11898 standard
has been implemented. The ETCPCx is implemented as a CAN Master.
The CAN interface is electrically isolated from the computer. The isolation
voltage to the computer is 500 V.

P4 allows for devices to be connected which are triggered by the PLC and
support the CANopen profile DS 301.
A maximum of 60 nodes can be connected electrically to the interface.
