Table 'Maximum number of I-Bus-modules'
Station type
I-Bus modules
1) Limited by software
2) Value based on experience (depends on cabinet size and/or 5V current consumption)
3) Battery charging unit E3C011 counts as one I-Bus module
All I-Bus modules are supplied with 24V and 5V. The available current for the 5V,
supplied from main CPU is limited:
'Main CPU'
B3Q700 / E3C011

* Not an I-Bus module, but supplied via the 'Main CPU'
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
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
