1.7.1.3.5 Addressing
A detailed description concerning addressing can be found in the documentation of ABB Control
Builder Plus Software.
The CANopen bus module reads the position of the rotary switches only during
power-up, i. e. changes of the switch position during operation will have no
effect until the next module initialization.
The range of permitted CANopen slave addresses is 1 to 127. Setting a higher
address (> 128) does not lead to an error response, but results in a special
mode (DS401). In this special mode, the device creates the node address by
subtracting the value 128 from the address switch's value.
1.7.1.3.6 I/O Configuration
The CI582-CN CANopen bus configuration is handled by CANopen master with the exception of
the slave node ID (via rotary switches) and the baud rate (automatic detection).
The digital I/O channels and the fast counter are configured via software.
