2.4.8.7 Digital Outputs states, Key to Press 'D'
This screen displays the output states, of the first 24 TC12 digital output boards;
each line represents 64 digital outputs i.e. one board. As there is the possibility of
16 boards in a rack the first 16 lines therefore would represent first rack.
This display is in colour and CTERM should be switched into the colour mode to
gain any information from this screen Press CNTRL K.
The colours used are as follows and correspond to shades as detailed below for
the monochrome screen used on the test set.
Colour
Blue
Red
White
NB If only two shades can be seen it may be possible to distinguish what is
being shown in the following ways.
If 'O' is pressed the screen will be blank if there is NO TC8, if TC8 is being driven
screen will show data. With this knowledge above screen can be interpreted as
TC8 Outputs are always the first shown on the above screen i.e. top lines.
2.4.8.8 Event flags, Key to Press 'E'
This screen and the flags are self descriptive, however on the terminal emulator
the line showing the state of the flags cannot be viewed and this screen is
therefore of no use under normal circumstances.
2.4.8.9 Free time, Key to Press 'F'
This screen shows the current, worst, best and average free time as percentages.
NB After re-booting the Instation PC worst percent free time goes to 0%, as during
initialisation it is allowed to use all time available for processing. To determine the
worst percentage free time during normal operation reset counters once operating
normally by pressing 'Z'. The worst percentage free after five minutes should be an
accurate figure for the system.
2.4.8.10 Help Screen, Key to Press 'H'
This screen lists all of the screens detailed in this section.
