Custom Data Display Monitoring
Selecting an existing screen or exiting the edit mode places the current Custom Display
screen in the monitor mode. Symbol display mode is the default for the screen. Data
format is indicated by a letter in parentheses after the value. The possible indicators
are:
( i ) Integer
( o ) Octal
( h ) Hex or BCD
( a ) ASCII
no indicator for binary or floating point
Binary formatted floating point numbers do not have special indicators, since the
format of the data is self-explanatory. Bit addresses display the word ON or OFF.
A sample Custom Display screen in monitor mode is shown below.
