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.
