Diagnostics
The 30 pilot lights on the front panel of the module are used in conjunction with the
two pushbuttons for diagnostics by the Twido controller.
The display block on the front panel of master module TWD NOI 10M3 allows
simpli ed local diagnostics to be performed by displaying the slaves present on the
AS-Interface.
Software set-up
AS-Interface is con gured using TwidoSuite (1) software.
The services offered are based on the principle of simplicity:
b Management of pro le tables, parameters and data by the master, in a way that is
transparent to the user.
b Topological addressing of I/O: each AS-Interface slave de ned has a topological
address assigned to it, in a way that is transparent to the user.
Each AS-Interface sensor/actuator is seen by the Twido programmable controller in
the same way as any “In-rack” I/O.

For plate or panel mounting of the module TWD XMT5 –
(1) When analogue and discrete modules are connected simultaneously to a system, the
analogue modules use addresses 1 to 31 in bank A. When an analogue module uses a certain
address, the module addresses having the same number in bank B cannot be occupied by
slaves in banks A/B.
