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

'Program file'

SRAM

Soldered

EPROM set

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.
