Replacing a Module
An
electronic unit
can be replaced at any time by a similar or compatible type,
even if the system is in operation.
When replacing a
whole module
(including socket), the following points must be
observed:
The bus connector protrudes from all TX-I/O devices on the right. For this
reason, the electronic unit must first be removed from the neighboring module
on the right.
The removal of the terminal socket interrupts the island bus so that modules on
the right no longer receive power.
To replace the module U (including socket) with the number n:
1.
First
swivel out the address key at the neighboring module U
n+1
(1)
2.
Remove the electronic unit U
n+1
(2)
3.
Remove the mounting slider at the terminal socket U
n
(3)
4.
Remove the whole module U
n
with the terminal socket (4)
5.
Install the new module U
n
with terminal socket – without an address key
6.
Push in the mounting slider U
n
7.
Insert the address key of the old module in the new module and swivel it into
position carefully
8.
Insert the electronic unit at the neighboring module U
n+1
again and carefully
swivel the address key into position.

Once the new electronic unit has a connection with the bus master, it is
configured in accordance with the module address and begins to work after a
brief period of time.
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 same procedure is used as for replacing an I/O module.
These devices have pluggable terminals for fast connection.
