Logic Module N 301

Description

The Logic Module N 301 applies logic operations, such

as AND and OR gates, to group addresses received.

One or more results of the logic operations can be

returned to the bus as group telegrams. This device

Selected applications allow you to allocate and

‘multiply’ received telegrams according to the actual

status of the selection objects (sensors).

The Logic Module N 301 performs different tasks

depending on the application program that is used. For

example, the number of logical inputs and outputs and

specific logic operations can be selected, and telegram

transmission may be controlled according to the

outcome of a certain logic operation.

ETS (Engineering Tool Software) is used to select the

application program, assign parameters and

addresses, and transfer this data into the Logic Module

N 301.

Application Programs

11 CO AND-8/2 720101 (8 inputs, 2 outputs)

One AND gate and one OR gate

8 inputs, 2 outputs. Inputs can be allocated to

either or both gates.

Inputs and/or outputs may be inverted.

Send conditions can be specified for each output

(for example, send on specific value or transition)

11 CO INV-4/4 740301 (4 inputs, 4 outputs)

Functions as inverter or pass-through for binary

signals.

4 inputs, 4 outputs.

Send conditions can be specified for each output

(for example, send on specific value or transition).

Value on bus voltage recurrence can be specified.

12 CO Binary 740A01 (Partition Control, 1-bit)

Forward switching telegrams from one object to

another based on four select-inputs. For example,

forwarding from one room section to another

depending on the position of moveable room

dividers.

Two groups with up to four different 1-bit group

addresses each.

12 CO Binary 740B01 (Partition Control, 8-bit)

Forward 8-bit value telegrams from one object to

another based on four select-inputs. For example,

forwarding from one room section to another

depending on the position of moveable room

dividers.

Two groups with up to four different 8-bit group

addresses each.
