8.2Control terminal limits (FC/FT)
8.2.1Limitation of visible texts on a FC700A
The number of texts of other stations (i.e. AREAS) that can be displayed on one control terminal is limited by 14'000 texts.
To evaluate how many control panels FC700A can be displayed to one FC700A, the following calculation must be used:
Twice the number of visible sections (worst case 1000)
+The number of visible ZONES (worst case 1000)
+The number of visible ELEMENTS with element text (worst case 1000) = Number of texts per FC/FT (worst case 4000)
Example (worst case)
14'000 : 4000 (e.g.) = 3 fully configured FC can be displayed to one FC
8.2.2Limitation of visible texts on a FT700A
The number of texts of other stations (FC700A) that can be displayed on one con- trol terminal is limited by 14'000 texts.
To evaluate how many control panels FC700A can be displayed to one FT700A, the following calculation must be used:
Twice the number of visible sections (worst case 1000)
+The number of visible ZONES (worst case 1000)
+The number of visible ELEMENTS with element text (worst case 1000) = Number of texts per FC/FT (worst case 4000)
Example (worst case)
30'000 : 4000 (e.g.) = 7 fully configured FC can be displayed to one FT
