Note
Use new CLPs
Only use a brand-new CLP or a CLP that was formatted by a gateway. The gateway formats
a brand-new CLP when it starts up with it.
CLPs that have already been used in other device types cannot be used for the gateway.
Startup of the gateway with configuration file on CLP
When a configuration file is saved on the CLP and you insert the CLP into a gateway, the
gateway always starts up with the configuration data of the CLP.
By inserting a CLP into a brand-new gateway or a gateway that was reset to factory settings,
you can cause the gateway to always start up with the configuration file saved on the CLP.
Function
An unwritten CLP (factory state) is automatically formatted for the gateway on startup of the
device.
The configuration of the gateway which you configure and apply is automatically backed up
on the CLP.
A device with an inserted CLP automatically uses the configuration data of the inserted CLP
when it starts up. This is, however, only possible when the data was written by a compatible
device type.
This allows fast and simple replacement of the basic device. If a device is replaced, the CLP
is taken from the failed device and inserted in the replacement. As soon as it starts up, the
replacement automatically applies the same device configuration as the failed device.
Inserting the CLP
Note
Insert and remove only when power is off
The CLP may be inserted or removed only when the power is off!
The slot for the CLP is located on the back of the device, see section CLP Slot (Page 24).
1. Turn off the power to the device.
2. Insert the CLP in the slot.
The CLP can only be inserted in one position.
Removing the CLP
1. Turn off the power to the device.
2. Insert a screwdriver between the front edge of the CLP and the slot and remove the CLP.
Diagnostics
General malfunctions of the CLP are signaled by the respective diagnostic message.
