Maximum number of texts
There is a limit to the number of texts of external stations (or AREAS) which can be displayed on an
operating unit (CT/CI).
The following calculation must be applied:
2x number of visible SECTIONS
+ number of visible OBJECTS
+ number of visible ELEMENTS with element text
= number of texts
'CT1142' limit value (B3Q661/681/686)
The maximum number of texts is fixed at 8500.
'CI1142' limit value (B3Q661/681/686)
The maximum number of texts depends on how many devices there already are in the control panel
configuration:
Number of texts per 100 non-configured devices
ELEMENTS per OBJECT
no
yes
reduce number of
visible AREAS or use
an additional control
terminal
maximum number
of texts
< X ?
the required number
of control terminals
is defined
The limit values for the station (CI/CC), gateway (CK) and additional AlgoWorks
programs must also be checked!
540
Example:
Average number of ELEMENTS per OBJECT: 5 = 540 texts per 100 devices
Free memory space: 600 devices (according to example shown in diagram in
section 9.1)
