9.1. Replacing modules
CAUTION
Risk of damage to equipment or malfunction as a result of uncontrolled machine stop.
Ì
The communication within the system is interrupted by the replacement of a module. If a process
is running, this situation can result in an uncontrolled stop and damage to the installation or the
product. Before replacement, make sure the installation is in a suitable operating status.
An interlocking/locking module with the BP configuration can be replaced only in combination with an overall system restart.
On the disconnection of the module connection, the system enters into a fault state. The related module and all downstream
modules remain inactive until the overall system is restarted (fault state).
Interlocking/locking modules with the configuration BR are hot pluggable. It is therefore not necessary to restart the overall
system.
9.2. Mounting submodules
CAUTION
Risk of damage to equipment or malfunction as a result of incorrect connection or a configuration
change.
Ì
Only submodules of connection types P, K and N can be used. Check the compatibility before instal-
lation. For information on the related connection type of a submodule, refer to the sticker on the rear
of the submodule or the data sheet for the related submodule. This is included with each submodule.
Ì
Pay attention to the alignment of the submodule. See marking (a) in
.
Submodules can also be installed rotated by 180°. The marking (a) always indicates the first posi-
tion to be equipped. This is the emergency stop S1 position in the example below.
Ì
Make sure the pins on the submodule slide straight into the guide. Tighten the cover screws to
0.5 Nm.
Ì
If you use a submodule, pay attention to the correct alignment of the modules in relation to the
labeling fields on the connection module. Incorrect assignments can cause serious malfunctions in
your installation.
Ì
Make sure no foreign bodies, e.g. swarf or wires, enter the open submodule slots. These can
cause short circuits or contact problems.
Ì
Avoid touching the contacts on the underside of the submodule. Risk of ESD damage and contact
problems due to soiling.
Ì
Unused submodule slots must be fitted with a cover (e.g. order number 126372).
