Ctrl Command set_input_pointer
Function sets the list input pointer to the specified address in the RTC
®
4 list buffer. The next list
command will be stored at this address. Also see chapter 5.6 "Structured Programming",
page 45.
Parameter
pointer
list input pointer [0 … 7999] as unsigned 16-bit value
Integration Pascal:
procedure set_input_pointer(pointer: word);
C:
void set_input_pointer(unsigned short pointer);
Basic:
sub set_input_pointer(ByVal pointer%)
Comments • This command can be used alternatively instead of the set_start_list commands.
• CAUTION: If the end of the list buffer is reached, the list input pointer is reset to zero.
Make sure not to overwrite any commands still needed by your application.

List Command set_io_cond_list
Function set the bits of the 16-bit digital output port that are set (=1) in
mask_set
,
if the current
IOvalue
at the digital input port meets the following condition:
((IOvalue AND mask_1) = mask_1) AND (((not IOvalue) AND mask_0) = mask_0)
(i.e. the
IOvalue
’s bits specified in
mask_1
must be
1
and the
IOvalue
’s bits specified in
mask_0
must be
0
).
Parameters
mask_1,
mask_0,
mask_set
unsigned 16-bit masks
Integration Pascal:
procedure set_io_cond_list(mask_1, mask_0, mask_set: word);
C:
void set_io_cond_list(unsigned short mask_1, unsigned short mask_0,
unsigned short mask_set);
Basic:
sub set_io_cond_list(ByVal mask_1%, ByVal mask_0%, ByVal mask_set%)
Comments • The command affects only those bits of the output port that are set (=1) in the param-
eter
mask_set
.
Examples
(Pascal)
• set bit #4 of the output port (DIGITAL_OUT4), if bit #0 of the input port (DIGITAL_IN0)
is HIGH and bits #1 to #3 (DIGTAL_IN1…3) of the input port are LOW:
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)
