For Compact version’s CAN configuration
“DIP Switch Configuration (SW1)” on page 3-35.
CAN ID (N
ODE
A
DDRESS
)
The CAN ID is set with input lines CAN ID1…CAN ID5. The node address (1…31) may be coded using
binary code.
Table 3-59
CAN ID – Pin assignment
The set CAN ID (node address) can be observed by adding the valences of all inputs connected exter-
nally to GND. Use the following table as a (non-concluding) guide:
Table 3-60
CAN ID – Examples
Setting the CAN ID by «EPOS Studio»
• The CAN ID may be set by software (changing object “Node ID”, range 1…127).
• The CAN ID set by the software is valid if the Node Address is set to “0” (all CAN ID input lines not
connected).
