11.10. Replacing submodules
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 submodule, and the
safe bits are reset. 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.
NOTICE
Pay attention to the information on the replacement of a submodule in the operating instructions for
the related module. On submodules with a safety function, the correct function must be tested after
replacement before the system enters normal operation again.
The replacement of submodules MSM while in operation is also possible (pay attention to safety note above). As soon as the
system detects a correct submodule, the submodule is ready for operation. The system reacts as follows on a replacement:
1.
If the submodule MSM is removed, the SLOT LED illuminates red, interrupted by 1x green flash. In addition, the SF LED
on the bus module MBM illuminates red.
2.
If the submodule MSM contains a safety function, the related bit on the bus is cleared as soon as the submodule has
been removed.
3.
If an identical submodule is inserted with the same alignment, the error display goes out and the bit is transmitted on
the bus again to suit the actual situation.
11.11. 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, and the safe
bits are reset. 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.
Modules (e.g. locking module or extension module) can be replaced only in combination with a restart of the overall system.
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).
11.12. Saving configuration
Changes to the configuration of the overall system must always be made in the configuration software for your control

. Depending on the change, a factory reset
might also be necessary.
