AC
power
from
either
the
Industrial
Terminal
System
or
the
PLC
Proces-
sor.
The
1770-T2
or
1770-T3, series B
Industrial
Terminal
System can be
connected
up
to
5000
cable-feet
from
the
PLC
Processor
by
using
additional
cable between
the
1774-TC
Cable
and
Channel
B
(Figure
4-3).
This
additional
cable
(Cat. No. 1778-CR,
Belden
8723
or
its
equivalent)
must
be
constructed
as
shown
in
Figure
4-4.
The
parts
required
to
construct
this
cable are listed in
Table
4-1.

CONNECTING
A
PLC-3
PROCESSOR
The
PLC-3
Processor
is
connected
to
the
1770-T4
Industrial
Terminal
System
for
pro-
gramming
using
the
PLC-31ndustrial
Terminal
Cable
(Cat. No.
1775-CAT).
The
end
of
the
cable
labeled
INDUSTRIAL
TERMINAL
END
connects
to
Channel
B
(Figure
4-5).
The
end
of
the
cable
labeled
PLC-3
END
is
connected
to
one
of
two
ports
on
the
PLC-3
Processor:
either
Channel
0
on
the
front
panel
or
Channel
5
on
the
1/0
Scanner-Programmer
Interface
Module
(Cat. No. 1775-S4A)
inside
the
PLC-3
Chassis.
The
1770-T4
Industrial
Terminal
System can
be
connected
up
to
5000
cable
feet
from
the
PLC-3
Processor
(Figure
4-6)
using
cable
constructed
from
Cat. No. 1778-CK,
Belden
8723
or
its
equivalent.
The
cable
diagram
in
Figure
4-7
shows
how
to
wire
the
pins
to
the
male
connectors.
The
parts
necessary
to
con-
struct
the
cable
are listed in
Table
4-1.

CONNECTING
A
SERIES
7100
CNC
The
Programmable
Interface
(PI)
Module
is
an
optional
software
feature
of
the
Series 7100
Computerized
Numerical
Control
(CNC).
It
consists
of
a
printed
circuit
module
that
can
be
programmed
much
like
a
programmable
controller,
using
ladder-diagram
instructions.
For
detailed
information
about
programming
and
operating
the
Series 7100
CNC
with
the
PI
Module,
refer
to
Programmable
Interface
User's
Guide
(Publication
7100-4.2).
The
1770-T1, -T2, and
-T31ndustrial
Terminal
Systems
can be
connected
to
the
PI
Module
using
the
1772-TC
Program
Panel
Intercon-
nect
Cable
(Figure
4-8).
One
end
of
the
cable
connects
to
Channel
A
on
the
Industrial
Ter-
minal
System.
The
other
end
connects
to
the
15-pin
socket
on
the
front
edge
of
the
PI
Module.
