CAN2 - Bus length and cable type
The type of cable to be used depends largely on the required bus length and number of nodes. The bus length is
determined by the bit rate. In accordance with CiA (CAN in Automation), the maximum bus length is 1000 meters.
The following bus lengths are permitted with a maximum oscillator tolerance of 0.121%:
Extension Transfer rate
≤1000 m Typ. 50 kbit/s
≤200 m Typ. 250 kbit/s
≤100 m Typ. 500 kbit/s

Table 72: CAN2 - Bus length and transfer rate
1) The specified cable length is only valid with the values specified in Tab. 66 "CAN driver settings" . Cable lengths additionally depend on the values in the
timing register.
The material used for the cable should have all or most of the following properties in order to achieve an optimal
transfer rate.

1) The interfaces, etc. available on the device or module have been numbered as such for easy identification. This numbering may differ from that used by
the particular operating system.
2) This interface can only be used in Automation Runtime and is referred to as IF2 in Automation Studio / Automation Runtime. It is not a "PC interface" and
therefore not shown in BIOS.
3.4.1.3.5 Shielding
For the interfaces on the 10-pin female connector, the interface shield can be put on pin 2 of the female connector.
