3.1.3 Set node address
Every ETCHx I/O module in a line represents a separate node at CAN1 bus and
must be set up with a unique node address.
ETC025
The node address is set via a front Hex switch (4 low value address bits) and
via permanently wirded bridges within the housing (3 high value address
bits). This means that a maximum of 16 modules are possible within a
module type.
)
Note!
Some modules have internal codings switches instead of the
permanently wired bridges for the optional modification of the
high value address bits.
