2.3.5.1.3.2 CAN bus 1 interface - Pinout
The CAN bus 1 interface on the system unit is referred to as "IF option".
A terminating resistor can be switched on or off for the CAN bus 1 interface. LED status indicator "L1" indicates
whether the terminating resistor is switched on or off.
CAN bus 1

The electrically isolated CAN bus interface is designed as a female 10-pin connector.

Table 118: 5ACCIF01.FPCC-000 - CAN bus 1 interface
1)
The interfaces, etc. available on the device or module have been numbered for the purpose of clear differentiation. This numbering may deviate from the
numbering used by the respective operating system, however.
2)
This interface can only be used in Automation Runtime and is displayed as IF3 in Automation Studio / Automation Runtime. It is not a "PC interface" and
therefore not displayed in BIOS.
CAN driver settings
The baud rate can be set either with predefined values or via the bit timing register. For additional information,
see Automation Help.

CAN1 - 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 transfer rate. According to CAN in Automation (CiA), the maximum bus length is 1000 meters.
The following bus lengths are permitted at a maximum permissible oscillator tolerance of 0.121%:

Table 120: CAN1 - Bus length and transfer rate
1)
The specified cable length is only valid with the values specified in
Tab. 118 "CAN driver settings"
. Otherwise, the cable lengths depend on the values in
the timing register.
