List Command write_da_2_list
Function see write_da_x_list
Integration Pascal:
procedure write_da_2_list(value: word);
C:
void write_da_2_list(unsigned short value);
Basic:
sub write_da_2_list(ByVal value%)
Ctrl Command write_da_x
Function writes a 10-bit value to one of the analog output ports of the RTC
®
4 or the
RTC
®
4 I/O Extension Board
Parameters
x
[1, 2] ANALOG OUT1 / ANALOG OUT2 ports on the RTC
®
4 board
[3, 4, 5, 6] ANALOG OUT ports on the RTC
®
4 I/O Extension Board (optional)
value
output value for the DA converter as unsigned 16-bit value.
Allowed range: [0 … 1023].
If a value > 1023 is specified, the output value is set to 1023.
Integration Pascal:
procedure write_da_x(x, value: word);
C:
void write_da_x(unsigned short x, unsigned short value);
Basic:
sub write_da_x(ByVal x%, ByVal value%)
Comments • For the ANALOG OUT1 / ANALOG OUT2 ports, the commands write_da_1 / write_da_2
can be used alternatively (without parameter
x
).
• Note that the output range of the ANALOG OUT1 port can be either 0 V … 2.56 V or
0V…10V (seepage 59), whereas the output range of the ANALOG OUT2 port is
always 0 V … 10 V. Also see the supplement manual "I/O Extension Board".
List Command write_da_x_list
Function same as write_da_x (see above), but a list command
Integration Pascal:
procedure write_da_x_list(x, value: word);
C:
void write_da_x_list(unsigned short x, unsigned short value);
Basic:
sub write_da_x_list(ByVal x%, ByVal value%)
Ctrl Command write_io_port
Function writes a value to the 16-bit digital output port on the “EXTENSION 1” connector
Parameter
value
output value as unsigned 16-bit value (DIGITAL_OUT0 … DIGITAL_OUT15)
Integration Pascal:
procedure write_io_port(value: word);
C:
void write_io_port(unsigned short value);
Basic:
sub write_io_port(ByVal value%)
Comments • Use the commands set_io_cond_list and clear_io_cond_list to set/clear individual bits
of the 16-bit digital output port, depending on the state of the input port.
