Reset Operations
Dual-process systems have a process reset operation, in addition to the
normal block reset and control reset functions. These reset operations
work as follows:
If you want to
perform a:
Press: The control will:
Block Reset [RESET] Skip the currently active block in the
currently selected process (see chapter
2).
Control Reset [SHIFT] + [RESET] Return the control to the default settings,
clear any program errors, and cancel
MDI commands in all processes (see
chapter 2).
‚
Process Reset [SHIFT] + [PROC SELECT] Return the program of the currently
selected process to the first block. Does
not affect the additional processes (only
works on programs executed from
control memory).
‚ If only one (or both) processes are still executing their part program when a control reset is
performed, only processes not currently executing a part program will have a control reset
performed. A message will occur in the processes executing the program stating that a control
reset is not allowed on that process.
Communication Between Processes (Shared Paramacro Parameters)
A link between the different processes of the machine is provided with the
dual-process shared paramacro parameters. These parameters are available
only on dual-process systems. They provide a link through which common
data can be passed between the different part programs executing in the
different processes of the machine. The shared dual-process parameters
are paramacro parameter numbers:
#7100 to #7199
Refer to page 28-36 for details on these paramacro parameters.
