This chapter describes the quantitative limits of the FC700A station.
The selection of the station type depends on the requirements. The following vari-
ants are available:
Flash ROM
Modules
(2x1024Kx8Bit)
'Program file'
B3Q700
CIY00760
B3Q700
CTY00760
E3H020
1000 devices (with AMPK=1) per FC700A.
The limits in the logical structure are given by the node-type, by the highest possi-
ble CSX number and the maximum amount of display-digits. These limits are given
by the system and are independent of the memory capacity.

The maximum number of control zones with 16 criteria is limited by 200.
To optimize the performance of your system minimize the number of CPU-overlapping controls as
much as possible.
A maximum of 40 CPU-overlapping controls (zone control 6) are admissible per C-Bus.
Max. 16 ZONES time channel are permitted per station.
