Description
This is indication data for
receiving analog data (unit:
ITEM number
%) from an analog output
ITEM in another function
block.
This is analog data (unit: %)
that is received from the
source designation specified
by the analog input
connection information
ITEM.
Analog data (unit: %) is sent
to the analog input ITEM of
another function block.

Contact signals are input
from the Step Ladder
ITEM number
Program block (Block Model
301) or the Contact
Distributor block (Block
Model 201).

Contact signals can also be
output to the Step Ladder
Program block (Block Model
301) or the Contact
Distributor block (Block
Model 201).
Exception:
Note that with some ITEMs the
source designation is sometimes
specified in the same way as
analog input for inputting contact
signals.
Contact signals are output
to Step Ladder Program
block (Block Model 301) or
the Contact Distributor block
× × ×
(Block Model 201).
Example
PV source designation
(ITEM006) of the Basic
PID block
PV input (ITEM007) of
the Basic PID block
MV output (ITEM087) of
the Basic PID block
Remote/Local switch
(ITEM026) of the Basic
PID block
High alarm output
(ITEM014) of the Basic
PID block
Section 3-1
Setting method
Specify the block address
of the source designation
and the ITEM number
(analog output ITEM).
Note: This data can also be set as
data for each ITEM or wired
in the software.
Á
This is not specified. (The
connection is made by
specifying output at the
send destination block.)
Contact signals are output
to the contact input ITEM
of the specified block
according to the output
instruction in the Step
Ladder Program block
(Block Model 301) or
according to the
destination of the Contact
Distributor block (Block
Model 201).
Note: Contact signals are input
once via the Step Ladder
Program block or the
Contact Distributor block
also from the System
Common block (Block
Model: 000, state output for
sequence control).
Contact signals are input to
the contact output ITEM of
the specified block
according to the input
instruction in the Step
Ladder Program block
(Block Model 301) or
according to the source
designation of the Contact
Distributor block (Block
Model 201).
