Addressing
In order for the automation station to be able to identify and address a specific
I/O module, each I/O module needs its own address.
Without an address key, the module is in a secure, inactive state.
The module is fully functional with the address key.
The module address is mechanically coded in the address key. It is inserted in
the I/O module socket and swiveled into the electronic unit.
Based on the address, the module is configured by the bus master via the island
bus and in this way receives the information as to what peripheral devices are
connected and what function is required for the periphery.
If the electronic unit is replaced, the address key must
first
be swiveled out.
The load is disabled as a result. The values remain stored in the bus master.
The key is left inserted in the terminal socket so that the bus master can inform
the new electronic unit of its function.
If you need a previously used electronic unit or used module as the replacement
part,
it must be reset to the factory settings with the deletion key
before the
address key is permitted to be swiveled into place.
The address key must first be
firmly inserted in the terminal socket
and then
carefully swiveled into the electronic part
.
