Special structures now need to be counted equivalent to the following number of
i
devices:
Structure
S D-Bus participants with an own D-Bus address (e.g. DOT1151,
DO1131, DM1154, DCW1151, DOW1171...)
S Each used input or output of interactive or AnalogPLUS I/O devices
Example: DC1157 with 3 Inputs Ü 6 devices
DC1154 with 1 output and 1 input for confirmation mes-
sage Ü 4 devices
S Purely logical controls: Each 'element command' or 'zone control'
not directly connected to a channel
S Collective lines (e.g. 1 line of module E3M080)
S Inputs of modules (e.g. E3X10x –> I4, E3L020 –> I2,
K3I110 –> LONin, external LON device –> LONin)
S Outputs of modules (e.g. E3X10x –> Q3, E3G050 –> Q1,
K3I110 –> LONout, external LON device –> LONout)
S Parallel indicator terminal/synoptic (equipped with up to 384 LEDs /
relays)
The limits in the logical structure are given by the node-type, by the highest possible CSX
number and the maximum amount of display-digits. These limits are given by the system
and are independent of the memory capacity.

To trigger a zone control 4 or 6, 1 to 16 criteria can be programmed.
Each criterion requires a certain amount of memory. Therefore the maximum number of
criteria is limited according to the following graphs.
Important:
If CPU-overlapping controls are used (zone control 6) all criteria which are NOT located
in the same control unit as the control zone have to be counted twice: once in the control
unit they are located and once in the control unit the zone 'control 6' is located.
Notes: 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 admissi-
ble per C-Bus.
