Declarations Overview

Declarations control the name, type, and number of inputs and outputs on a SIMPL+
symbol. The name is shown as a cue on the symbol in SIMPL Windows and is used
as the variable name in the body of the SIMPL+ program. When the symbol is drawn
in SIMPL Windows, the inputs are shown in the order of DIGITAL_INPUTs,
ANALOG_INPUTs, STRING_INPUTs. The outputs are shown in the order of
DIGITAL_OUTPUTs, ANALOG_OUTPUTs, STRING_OUTPUTs. When
specifying a declaration, several variable names can be put after a declaration or
multiple declaration statements may be used.
For example:
ANALOG_INPUT val1, val2, val3;
is equivalent to:
ANALOG_INPUT val1, val2;
ANALOG_INPUT val3;
Allowable I/O List Combinations
SIMPL+ Version 2.00 and later gives the ability to define arrays in the Input/Output
Lists. SIMPL+ version 3.01 and later introduced the ability to declare multiple fixed-
size arrays in the input/output lists, and a minimum expanded size to variable-size
arrays.
The following are the allowable combinations:
•
Zero or more DIGITAL_INPUTs
•
Zero or more DIGITAL_INPUT arrays, the last is variable-size, the others are
fixed-size.
•
Zero or more ANALOG_INPUTs, STRING_INPUTs, or BUFFER_INPUTs
in any combination.
•
Zero or more ANALOG_INPUT, STRING_INPUT, or BUFFER_INPUT
array, the last is variable-size, the others are fixed-size.
•
Zero or more DIGITAL_OUPUTs
•
Zero or more DIGITAL_OUTPUT array, the last is variable-size, the others
are fixed-size.
•
Zero or more ANALOG_OUTPUTs, STRING_OUTPUTs in any
combination.
•
Zero or more ANALOG_OUTPUT or STRING_OUTPUT array, the last is
variable-size, the others are fixed-size.
