How to Use Function Blocks for Specific Operations
To perform this specific operation
Sequence AND, OR and other logical operations on
control the Loop Controller
One-shot contact output of the ON input
state when the contact state changes
from OFF to ON and vice versa only in 1-
operation cycles (system common opera-
tion cycle)
Constantly ON contacts and other system
contacts
Step progression control and other con-
trol on the Loop Controller
Acceptance of bits in the Step Ladder
Program
Execution of special processing at each
fixed cycle longer than operation cycle in
Step Ladder Program
Execution of timers/counters on the Loop
Controller
Constant Constant transmission of constants as
set- analog signals
ting/selec-
Setting of constants to specified ITEMs
tion
under certain conditions
Selection of one of multiple constants and
transmission of that constant as an ana-
log signal
Changing PID constants and other
parameters in stages according to a pro-
cess value (e.g., temperature).
Perform the following
Use the Sequence Table block (Block Model
302) or Step Ladder Program block (Block
Model 301).
Use the Internal Switch block (Block Model
209).
Generate a fixed cycle timing signal by the
Clock Pulse block (Block Model 207).
Use the Timer block (Block Model 205) and
the Counter block (Block Model 208).
Use the Constant Generator block (Block
Model 166).
Use the Constant Item Setting block (Block
Model 171).
Use the Constant Selector block (Block
Model 165).
Use the Level Check block (Block Model
210) and the Constant ITEM Setting block
(Block Model 171) together to change
parameters for other blocks according to the
level.
