TIME 1: The message 054 (for example) is invoked and displayed
without
variables (Time 1-2 >= 74 ms)
TIME 2:
The function input TEXT/VARIABLE is switched to variable
(Time 2-3
>= 21 ms)
TIME 3:
The 1st variable is created, CLOCKed into the LCA042 in BCD/
ASCII-code via the message inputs and displayed. The variables
are written into the predetermined variable positions from
left to right (Time 3-4
>= 15 ms)
TIME 4: After the CLOCK there is an “idle time” (Time 4-5 >= 15 ms)
TIME 5: The 2nd variable is created, CLOCKed into the LCA 042 in BCD/
ASCII-code via the message inputs and displayed. The variables
are written into the predetermined variable positions from
left to right (Time 5-6
>= 15 ms)
TIME 6: After the CLOCK there is an “idle time” (Time 6-7 >= 15 ms)
TIME 7: The text is displayed with variables until time point 7
4.4 EXTERNAL VARIABLES
External variables are pressures, temperatures, counter
values etc. They can be read into any message text line.
The variables in an invoked message can be updated as
often as desired:
By means of place holders * (asterisks) you can determine
the number and position of the variables in a text line:
A maximum of 40 external variables can be written into
each text line.
