Subject : Setting "Cycle to cycle" mode from an input signal
Keywords: Cycle to Cycle - Run/stop hardware command
An input signal can be used to set the "Cycle to cycle" or "Real
time" execution mode for the ISaGRAF cycle. This corresponds to the
run/stop hardware command on a common PLC. Below is an example of
input driver programming:
#include <tasy0def.h> /* main ISaGRAF definitions */
extern str_system *SYST; /* internal ISaGRAF structure */
/* to be added in a boolean input driver routine */
/* state is the boolean state of the input signal */
SYST->mode_ker = RT; /* set up real time mode */
SYST->mode_ker = CC; /* set up cycle to cycle mode */
WARNING: When this input driver is actif, the corresponding "cycle
to cycle" and "real time" commands of the ISaGRAF debugger cannot
be used anymore.
When the kernel is blocked in cycle to cycle mode, inputs, outputs
and communication with debugger are still handled.
