Flow-control instructions
A Flow-control instruction causes the program to jump to a specified
instruction or to be terminated (eg.
GOTO
).
Maths functions
A Maths function applies a mathematical operative to an expression to
return a value (eg.
SIN
).
Signal-processing functions
A Signal-processing function returns a value from a number of samples over
a fixed time-period. Signal-processing functions can be used only in the
SPEED, CLOCK
or
ENCODER
tasks (eg.
FILTER
).
Base-conversion functions
A Base-conversion function acts upon a value to convert Binary Coded
Decimal to Binary and vice versa. Base-conversion functions are useful for
data received from an IO Box. Refer to Chapter 6 Serial Communications.
Data-conversion functions
A Data-conversion function converts a floating-point variable to an integer
variable and vice versa.
ANSI instructions
An ANSI instructions allows a DPL program to communicate via the
RS485
port with other Drives and
UD70
cards using the
ANSI
protocol. Refer to
Chapter 6 Serial Communications.
