CANio 500 Quickstart Manual, version 1.3

5.1.14 Reserved CAN identifiers

To guarantee a basic communication, the CANio 500 uses specific CAN identi-
fiers. These identifie

rs can’t be changed.

List of the reserved CAN identifiers:

CAN Identifier

Meaning

0x000

Command to steer the state machine of the CANio
500: see 5.1.15

0x600 + node number
0x580 + node number

These identifiers are reserved for configuration mes-
sages.

0x700 + node number

This identifier is reserved for the heartbeat message.

Even in case that the CANio 500 shall not generated
heartbeat messages, at the end of it’s initialization it
will transmit a Bootup message. The Bootup message
uses this identifier.

0x7E5
0x7E4

These identifiers are reserved for messages to config-
ure the node number and the CAN baudrate.

5.1.15 Steering the state machine of the CANio 500

The internal state machine of the CANio 500 can be steered by a specific
command:

CAN identifier

Data field (length = 2)

Byte 0

Byte 1

0x000

Command

Node number

Description of the node number:

Node number

Consequence

0x00

Every CANio 500 in the network needs to execute this com-
mand

0x01

– 0x7F

The CANio 500 using the selected node number needs to exe-
cute the command. Else the command is ignored.

else

Is ignored
