List Command
set_io_cond_list
Function sets the bits of the 16-bit digital output port on the EXTENSION 1 connector that are set
in the parameter
MaskSet , if the current IOvalue at the 16-bit digital input port on the
EXTENSION 1 connector meets the following condition:
((IOvalue AND Mask1) = Mask1) AND (((not IOvalue) AND Mask0) = Mask0)
(i.e. if the bits specified in Mask1 are 1 and the bits specified in Mask0 are 0 ).
Call
set_io_cond_list( Mask1, Mask0, MaskSet )
Parameters Mask1,
Mask0,
MaskSet
16-bit masks as unsigned 32-bit values
(only the least significant 16 bits are evaluated)
Comments • The command sets only those bits of the digital output port that are set in the
parameter
MaskSet and leaves the other bits unchanged.
• Also see section "16-Bit Digital Input and Output", page 49 and "Conditional Command
Execution", page 213.
Examples
(Pascal)
• set bit #4 of the output port (DIGITAL OUT4), if bit #0 of the input port (DIGITAL IN0)
is set and bits #1 to #3 (DIGITAL IN1…3) of the input port are not set:
set_io_cond_list($0001, $000E, $0010)
• always set bit #15 of the output port (and leave the other bits unchanged):
set_io_cond_list(0, 0, $8000)
