AVCO 8800 (active)

The active AVCO 8800 is a linux-based application that replaces a USEC MODCOMP II Unit Computer. All linux-based versions of the 8800 software are broken into two parts: the resident core and the user interface. The core will run automatically as part of the system start up sequence when PICS is running and available. To run the user interface, one must either use a local console (i.e. a directly attached keyboard and display) or remotely connect using an SSH (secure shell) client program across the 8800 network. When using the local console, the user interface display will look very much like the samples below. When using a remote shell, you may see more (or less) than is shown here because generally, remote shells allow the window to be any size, while the local console is fixed at 80 columns and 25 rows.

Common Screen Areas

Area Name Area Content

Build Info Most of the top two lines of the primary screen contain build info. The first number shown is the current build of the user interface program, followed by the build string from the resident 8800 program. The next object is a greater than (or greater than or equal) sign, indicating how significant change testing is performed. The last items on the first line are the 8800 number and side, followed by the 8800's IP address.
The second line contains the resident 8800 program's version number, build flags, hwardware type, watchdog type and the currently controlling MUX name (if any).

Status Line This line (plus the qSec item at the end of the fourth line) provide an overview of the 8800's current operational state. A functional and scanning 8800 should have a status of 'good', state of 'primary', control of 'online' and the MLC (main loop counter) and qSec (current quarter second) should be changing.

Scan Info The 8800 counts every attempt to scan a point, whether or not the attempt succeeded and when a new (sigchg) or refreshed value is sent to PICS. This section shows the current values for those counters.

Network Info Shows the number of network messages sent and received by the 8800. If any send/recv errors are detected, the number of those is also shown here.

Memory Usage This section shows exactly how many bytes of memory are being used for various parts of the database used to scan, convert and alarm points.

Message Logging Current settings for the 8800's message logging facility are shown here. The filters control which messages are logged and which are not. The debug option determines if the name and line number of the source file where the message originated are included. Warning: excessive logging will impact the 8800's performance and is only recommended when trying to track a particular problem. Typically, the default settings are more than adequate.

Time Sync The 8800 core interfaces with EVI's time sync monitor program to determine the quality of the local clock relative to the time standard from the network. When the time is too far from the standard (or the standard is unknown) the 8800 considers the time unusable and marks the PICS Time point it provides accordingly. When the standard is known, the 'sync' value shows the IP address where the standard was found; the drift value shows how far from the standard the local clock is currently running; reference shows the UTC and local time that the standard was last accessed; update shows the most recent time update; and PICS Time shows whether or not the 8800 is marking the time point as usable.

Hardware-specific: AVCO The AVCO panel includes some byte and packet counters to show how much data has been sent/recv'd on the serial ports.

Menu The menu (usually shown in the bottom right corner of the display) is on a magenta background to separate it from the 8800 data. The keys show are case sensitive, so be careful to watch for CAPS lock being on. Some of the displays (like 'Big Log') use the entire lower part of the screen, so the menu is moved to the 4th and 5th lines of the screen in order to maximize the space available for the log (or other functions)
