C-PLUG Configuration Memory

Description
The C-PLUG is an exchangeable medium for storage of the configuration and project
engineering data of the base device. This means that the configuration data remains
available when the basic device is replaced. It is therefore used when the replacement of
network components or communications modules needs to be quick if a fault occurs without
needing to configure a replacement and without needing specialist personnel. As a result,
downtimes of network segments and connected Industrial Ethernet nodes can be minimized
if a fault occurs.
The C-Plug can be used in all SIMATIC NET products with a C-PLUG slot.
Structure
The C-PLUG has IP20 degree of protection. With IP65 components the protection is ensured
because the C-PLUG is installed inside the protected housing.
Power is supplied by the end device. The C-PLUG retains all data when the power is turned
off.
Function
If an empty CPLUG (as supplied) is inserted in a SIMATIC NET component, the device
automatically backs up the configuration data during startup. Changes to the configuration
during operation are also saved on the C-PLUG without any additional operator intervention
being necessary.
When an unconfigured device starts up, it automatically adopts the configuration data of an
inserted C-PLUG assuming the data was written by a compatible device type.
The C-PLUG can also be used to store application data such as documentation or Web
pages.
