Limit comparator texts, external text, binary-linked external text
Limit
comparator
texts
Limit comparator texts can be printed out. To do this, the parameter Configu-
ration level 1
Î
Limit comparator
Î
Limtext state must be set to ON and the
corresponding texts must be entered. Every time that a measurement goes
above or below a limit value, the appropriate text will be printed.
v Section 3.1 “Limit monitoring by limit comparators”
External text
There are eight logic inputs available for external texts.
If a logic input is closed (positive edge triggering) then the corresponding text
will be printed. Opening the logic input has no effect.
The function is activated by the parameter Configuration level 3
Î
External
text.
Binary-linked
external text
(text logic links)
It is possible to interpret the signals on the first four logic inputs as a binary
number, and to associate a text with each binary number. Up to 16 texts can
be defined in this way.
The text which is assigned to the binary number is printed out after every
change of state of the logic inputs concerned.
Text printing can be switched off individually for each of the 16 texts.
Example:
If the binary number 1001 is present on the logic inputs, then text 9 will be
printed.
If logic input 1 is opened, then the binary number 1000 is present on the logic
inputs, and so text 8 will be printed.
H
Extra code “Logic inputs” is required.
If this extra code is not present, then the parameter will not be
displayed.
