usage, and system setup. The table below shows an approximate time delay before starting operation after powerup.
Response time when no data link is used:
Program Size
4,800 bytes (800 steps)
15,000 bytes (2,500 steps)
27,000 bytes (4,500 steps)
64,500 bytes (10,750 steps)
Order of Powerup and Powerdown
To ensure I/O data transfer, power up the I/O modules first,
followed by the CPU module, or power up the CPU and I/O
modules at the same time. When shutting down the system,
power down the CPU first, followed by I/O modules, or
power down the CPU and I/O modules at the same time.
Start/Stop Operation Using Stop Input and Reset Input
Any input terminal available on the CPU module can be designated as a stop or reset input using the Function Area Set-
tings. The procedure for selecting stop and reset inputs is described on page 5-2.
Note: When using a stop and/or reset input to start and stop operation, make sure that start control special internal relay
M8000 is on. If M8000 is off, the CPU does not start operation when the stop or reset input is turned off. M8000 is not
turned on or off when the stop and/or reset input is turned on or off.
When a stop or reset input is turned on during program operation, the CPU stops operation, the RUN LED is turned off,
and all outputs are turned off.
The reset input has priority over the stop input.
System Statuses at Stop, Reset, and Restart
The system statuses during running, stop, reset, and restart after stopping are listed below:
Mode
Run
Stop (Stop input ON)
Reset (Reset input ON)

Note: Expansion data registers and AS-Interface operands are available on slim type CPU modules FC4A-D20RK1, FC4A-
D20RS1, FC4A-D40K3, and FC4A-D40S3. All expansion data registers are keep types. AS-Interface operands (M1300-
M1977 and D1700-D1999) remain unchanged when the reset input is turned on.
