You can advance through Input Storage by
keying in the advance command, A, or backup
by keying in the backup command, B. The Input
Location you are observing is shown on the left
in the display ID field. The temperature data
stored in the Input locations are updated every 2
seconds, each time Table 1 is executed. Verify
this by changing the temperature of the
thermocouple (hold it in your fingers) while
monitoring the proper Input Location. It is possible to go directly to a specific Input
Storage location by entering the *6 Mode and
keying in the desired location before keying A.
A similar utility is available in other Modes.
OV4.2 OUTPUT
In the following example instructions are
appended to Table 1 to output the time and the
average temperatures to Final Storage every 5
minutes.
