5.2.2 Configuration
This menu contains functions for configuring the device. The functions are available both on the device
and in the setup program (see the "Configuration" chapter in the operating manual).
In addition to this, there are functions that can only be configured with the setup program (see the oper-
ating manual, chapter "Configuration - only in setup program" and "Online parameters").
CAUTION!
Changing the configuration closes the current capturing of recording data and means the new
data is recorded such that it is chronologically separated from the old data (new configuration =
new archive section). As a basic principle, the device only stores the recording data that has
been captured during the last 20 configurations. However, irrespective of this, the oldest data is
automatically overwritten with new data when the internal memory is full (ring buffer principle).
The data before and after the reconfiguration cannot be displayed as a whole in PCA3000. Data which
is older than the last 20 configurations can no longer be extracted from the device.
Before making any changes to the configuration, always create a backup of the data. It is also nec-
essary to select suitable retrieval cycles for the data to prevent data loss. The setup program (con-
figuration of the groups) provides a guideline value for the maximum data capture time.
5.2.3 Parameterization
This menu contains the functions for parameterizing the device (see the "Parameterization" chapter in
the operating manual).
5.2.4 Device information
This menu contains information about the device (name, versions), the current process values (inputs,
outputs, internal functions), the Ethernet interface, and the PROFINET interface (optional extra).
The device version is indicated through the "Version" parameter in the submenu "Versions" > "Basic de-
vice":
Standard = device in standard version
21 CFR Part 11 = device in FDA compliant version
With extra code 887 (digital certificate) or 888 (FDA) information about the digital certificate is also dis-
played in this menu.
5.2.5 Audit trail list
This menu lists the audit trail messages generated by the device.
All user intervention with the device is automatically recorded and stored in the audit trail list of the de-
vice. The audit trail list is managed independently of the event list.
The audit trail list is designed as a ring buffer which can contain a maximum of 150 entries. When the
list is full, each new entry causes the oldest entry to be deleted from the list.
