11.3. Controlling and Supervising the 8 TeSys U Motor Starters

The “Supervision Control” operating screen (see picture below) is meant to monitor the status of the 8 TeSys U
motor starters, numbered from 1 to 8. It is also meant to control them individually using several buttons.

Registers 455 and 704 of each of the 8 TeSys U motor starters are used to conduct this control and supervision:

455 – TeSys U status register (IEC61915)

Bit 0 ..........Motor starter ready
Bit 1 ..........Contactor in the ON position (

1

)

Bit 2 ..........Fault (trip or dropout)
Bit 3 ..........Alarm presence
Bit 4 ..........Specific: Tripped (

I >>

)

Bit 5 ..........Specific: Fault reset authorized
Bit 6 ..........Specific: A1-A2 supply
Bit 7 ..........Specific: Motor running
Bits 8-13 ...Motor current (2#10 0000 = 200%)
Bit 14 ........Reserved: Local control
Bit 15 ........Ramping (motor starting)

704 – (IEC61915) command register

Bit 0 ..........Reserved: Run forward
Bit 1 ..........Reserved: Run reverse
Bit 2 ..........Reserved (stopping)
Bit 3 ..........Reset
Bit 4 ..........Reserved (emergency start)
Bit 5 ..........Self test: Triggering test (trip)
Bit 6 ..........Reserved (low speed)
Bits 7-11 ...Reserved by the IEC61915 standard
Bit 12 ........Specific: Overload (shunt trip)
Bit 13 ........Specific: Pause (reserved for adjustment)
Bits 14-15 .Specific: Reserved

These statuses and controls are grouped in two sections: “General Status”, for the general operating mode of
the motor starters, and "Motor" for the general operating mode of controlled motors. The last section, “DEBUG
COMM.”, displays the registers %IW and %QW used for each motor starter.

This screen is represented below, but only for the first motor starter, as it is identical for the 7 others.

Most displays in this operating screen are directly tied to the %MW
registers containing the values of registers %IW4.0.1 to %IW4.0.8 and
%QW4.0.1 to %QW4.0.8 (status and command registers of the TeSys U
motor starters). Only the indirect controls and statuses are described
below.

The “Cmd_mon” program conducts the following tasks:

• Copy the values of words %MW20 to %MW27 to output registers

%QW4.0.1 to %QW4.0.8, and copy the values of input registers
%IW4.0.1 to %IW4.0.8 to words %MW10 to %MW17.

These data are copied because word bit extraction can be carried out
on %MW indexed words, but not on %IW indexed words. Actually, the
sub-program “Sr0” uses word indexing to a large extent, as it makes it
possible to process any motor starter, since it is designated by the word
%MW0.

E.g.:

“%MW10[%MW0]:X13” is allowed, but not

“%IW4.0.1[%MW0]:X13”.

Furthermore, the input and output words are copied one by one, as
PL7 PRO does not support expressions such as “%IW4.0.1:8”.

“Sr0” sub-program calling loop, whose purpose is to control and

monitor of the 8 TeSys U motor starters. Upon each iteration of this
loop, the word %MW0 (“Module”) takes a value from 0 to 7 in order
to be used as an index for words %MW10 to %MW17 (inputs) and
%MW20 to %MW27 (outputs).
