The XSeries
G5
embedded software is modularized and flexible. The software includes a complete suite
of applications, each of which can be activated and configured to meet specific functionality
requirements or disabled to reduce allocation of system resources. XSeries
standard applications required for basic system operation and local communication. Additional
applications can be enabled at the factory, per request, or activated later by the customer.
While both the XFC
G5
and XRC
designed for different field scenarios and implementation scope. The type and number of applications
enabled in each device type will vary depending on the site scenario. The following sections describe
device-specific functionality and typical use.
IMPORTANT NOTE: This manual does not provide an exhaustive list and description of all the
applications available. For detailed application description see PCCU online help topics. Each
application has context-sensitive help for each of its related configuration/monitoring screens.
Data retention (may be limited by file space on the device) values are set to:
40 days of hourly log period data records
50 days of daily data records
200 event registers
1.2.1
Operating system
The XSeries
devices use a thread priority preemptive real-time operating system (OS) (Linux-
G5
based). This design prioritizes real-time functionality (measurement and control applications) before
executing non-real-time functionality (post measurement data processing and file system access).
The OS file system is composed of a RAM file system and an eMMC data journaling file system. The
applications access the RAM file system, which provides increased performance. The RAM file system
is backed up into the eMMC file system for the following triggers:
One time per minute on the fourth second of each minute
Before all warm restarts (triggered from PCCU32 Station Setup, terminal mode, PCCU32
device loader, or reset button)
A large capacitor provides power for 2.5 seconds to the system in the event of a power loss. This
allows the software to safely shutdown the eMMC file system. The system data not backed up by the
one-minute periodic update will be lost.
