Program Channels
Up to thirty-two inputs of broken line data can be included in expressions.
Multiple points can be set for the time from the start point and the output value at that
point. Specified points are linked with a straight line, the value of Y at the elapsed time X
is output. There is Single, in which one cycle is executed, and Repeat in which execution
repeats. By specifying a MATH channel to which broken line input is assigned to the
reference channel of an analog output channel, you can output arbitrary patterns.
• Example
X : Elapsed time (s)
Y : Output
(0.0)
(10.500)
(20.500)
(30.800) (40.800)
(50.0)
• Entry Example
Input of broken line data in the example is as follows.
(0.0), (10.500), (20.500), (30.800), (40.800), (50.0), (-1.0)
If there are fewer than thirty-two setting points, a (-1.0) is required to show the end of
the points.
• Operation of program channels for the computation operation
Computation Operation Program channel operation
Computation start Starts broken line computation from the held elapsed time
Computation stop Holds the broken line computed value
Computation clear Resets the elapsed time to 0 and start the broken line computation
from the beginning
Computation reset During self-computation, 0-clear the elapsed time and start the
broken line computation
• Operation after Elapsed Time
Mode Notation Program channel operation
Single Single Holds the broken line computed value of the last point
Repeat Repeat Returns to the start point then repeats broken line
Computation Operation
Starting and Stopping Computation
Execution of computation starts and stops according to user commands (Start/Stop key,
Event/Action function, or monitor screen settings).
Clearing Computations
Clears all MATH channel data (including MATH alarms) per the Event/Action function,
communication commands, or requests from the monitor setting screen.
Resetting Computation
Clears all MATH channel data (including MATH alarms) per the Event/Action function,
communication commands, or requests from the monitor setting screen. If this request
occurs during a computation, it is executed on the next computation interval and
computation starts. Also, if the request occurs while the computation operation is
stopped, it is cleared when computation starts.
