Operating Mode Changes and I/O Memory
Note
1.
The following processing is performed if the I/O Memory Hold Bit is ON.
Outputs from Output Units will be turned OFF when operation stops even
if I/O bit status is held in the CPU Unit.
2.
The cycle time will increase by approximately 10 ms when the operating
mode is changed from MONITOR to RUN mode. This will not, however,
cause an error for exceeding the maximum cycle time limit.
Note
Refer to
SECTION 4 I/O Memory Allocation

A Programming Console cannot be connected to the CP1L.
RUN
• Any task that has not yet been executed, will be in disabled status (INI).
• A task will go to READY status if the task is set to go to READY status at star-
tup or the TASK ON (TKON) instruction has been executed for it.
• A task in READY status will be executed (RUN status) when it obtains the
right to execute.
• A status will go to Standby status (WAIT) if a READY task is put into Standby
status by a TASK OFF (TKOF) instruction.
Executed if inter-
rupt condition is
met.
