8 Limitations of C-Bus participants
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:
Station type Modules
Flash ROM
(2x1024Kx8Bit)
'Program file'
SRAM
Soldered
EPROM set RAM set
FC700A B3Q700 CIY00760 4x512Kx8Bit – –
FT700A B3Q700 CTY00760 4x512Kx8Bit – –

8.1 Main CPU limits
8.1.1 Maximum number of devices
1000 devices (with AMPK=1) per FC700A.
8.1.2 Limits in the logical structure
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.

8.1.3 Maximum number of criteria in zones control 4 and 6
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.
8.1.4 Maximum number of ZONE time channel
Max. 16 ZONES time channel are permitted per station.
