define the required number of
control terminals by going
through this flow chart
The number of texts of other stations (i.e. AREAS) that can be displayed on one control
terminal (CT/CI) is limited.
The following calculation must be used:
twice the number of visible SECTIONS
+ the number of visible ZONES
+ the number of visible ELEMENTS with element text
= number of texts
Limit for 'CT1142' (B3Q460/480/670, B3Q660/680/685)
The max. number of texts is fix 8500.
Limit for 'CI1142' (B3Q460/480/670, B3Q660/680/685)
The max. number of texts is depending on the number of devices already configured in
the control unit.

Example:

Free RAM space: 600 devices

–> maximum number of texts: 540 x 6 = 3240 texts
