Command
read_io_port_list
Function Writes into the internal IOPort buffer the current state (DIGITAL IN0…DIGITAL IN15) of the
EXTENSION 1 socket connector’s 16-bit digital input port. At the same time, the current
xy set positions and relative time in seconds are stored.
Call read_io_port_list()
Comments • read_io_port_list does not return values. However, the values can be subsequently
queried from the IOPort buffer by the read_io_port_buffer command.
• The IOPort buffer holds 4,096 entries and is circularly organized. It always stores the
4,096 most recent entries and overwrites older entries without warning. The
incremental Index starts after a reset (program start) at Index 0, and after passing
4,095 does rollover to 0.
• The stored time is the current value of an internal seconds counter that is set to 0 at
program start (load_program_file) or by time_update.
• See also Chapter 9.2.1 ”16-Bit Digital Input Port”, page 288.
RTC4RTC6 New command.
