AS-Interface master module TWD NOI 10M3 allows
the Twido controller (version u 2.0) to perform the
function of AS-Interface master.
The AS-Interface consists of a master station (Twido
controller) and slave stations. The master, which
supports the AS-Interface pro le, polls each of the
devices connected to the AS-Interface, in turn, and
stores information gathered (sensor/actuator status,
operating status of the devices) in the controller
memory. Communication on the AS-Interface is
managed in a way that is totally transparent to the
Twido application program.
The TWD NOI 10M3 master module manages the
following with the AS-Interface M3 pro le:
b discrete slave modules (maximum of 62 slaves
arranged in 2 banks, A and B, of 31 addresses each),
b analogue slaves (maximum of 7 slaves in bank A).
The AS-Interface M3 pro le supports analogue pro le
7.3 (7 slaves), but does not support analogue pro le
S-7.4.
The maximum number of TWD NOI 10M3 modules per
Twido controller is 2.
An AS-Interface power supply is essential to supply the
various modules on AS-Interface. It should preferably
be located close to the stations with high power
consumption.

Description
Module TWD NOI 10M3 takes the form of a standard-size module. It is connected to
a Twido base controller (compact or modular) in the same way as any I/O module.
It has the following on the front panel:
1 A display block comprising:
b 6 pilot lights indicating the module operating modes:
v green PWR pilot light: module powered up,
v red FLT pilot light: error in the con guration loaded,
v green LMO pilot light: module in local mode,
v green CMO pilot light: module in connected mode,
v red CNF pilot light: not used,
v red OFF pilot light: module in protected, unconnected mode.
b 6 green pilot lights, 3 for inputs, 3 for outputs.
2 A block for displaying the status of the addresses.
3 Two pushbuttons PB1 and PB2 for controlling the status of the slaves by selecting
their address and changing the mode.
4 An extension connector for electrical connection to the previous module.
5 A connector (on the RH side) for I/O expansion modules TWD Dpp and TWD App
(4 or 7 depending on version).
6 A latching mechanism for attachment to the previous module.
7 A power supply removable screw terminal block.
Expansion module TWD NOI 10M3 can be mounted as standard on symmetrical
5 rail. Fixing kit TWD XMT5 (sold in lots of 5) allows plate or panel mounting.
