nCreating
a
Project
File
The
following
descripton
provides
information
about
how
to
create
a
project
file
to
send
the
RUN
command
and
frequency
references
to
three
Inverters
and
read
the
Inverter
status.
(“PST”
indicates
the
WS01-PSTF1-J
Protocol
Support
Tool.)
First,
select
from
I/O
items,
monitor
items,
and
parameters
the
data
to
be
exchanged
according
to
the
applica-
tion.
Then
consider
what
sequence
is
required
by
using
the
protocol
macro
function.
Example:
Writes
control
input
items
(such
as
the
RUN
command
and
multi-function
input)
of
the
Inverter
and
frequency
reference,
monitors
the
control
output
(such
as
error
output
and
RUN
output)
of
the
Inverter,
and
monitors
the
Inverter
status.
Three
Inverters
with
Slave
addresses
from
01
to
03
are
installed
for
communications.
Checking
the
Register
Numbers
In
the
above
example,
the
following
three
registers
are
required.
Control
Input:
Register
0001
Hex
for
RUN
command
Frequency
Reference:
Register
0002
Hex
Control
Output:
Register
002C
Hex
for
Inverter
status
Memory
Allocations
The
PMCR
instruction
sends
each
Slave
the
data
in
consecutive
words
specified
by
the
operand
and
beginning
with
the
first
word
(S),
and
writes
in
the
memory
area
beginning
with
the
first
word
(D)
the
data
received.
The
following
memory
allocations
are
made
in
the
above
example.
