Description of Operation Section 3-2
send/receive data is then read from the CPU Unit's HMI data area (in the EM
area) and written to RAM.
Hot start within specified time (ITEM018 = 0)
When operation is started in hot start mode (ITEM018 = 0), a hot start is per-
formed after recovering from a power interruption if the time that power is
interrupted is a within the time specified in ITEM037 (Hot start enabled time: 0
to 3,600 s (1 hour)). Cold starts are performed if power is interrupted for
longer than this time.
If a hot started within specified time is specified, but a cold start is used
because the specified time has been exceeded, the cold start will differ from
normal cold starts in that the parameters for control and operation blocks and
the SPs for control blocks will not be read from flash memory and the HMI
interface data area, i.e., the data that is already in RAM will be used. For CS-
series PLCs, however, a normal cold start will be used if the power has been
interrupted for more than 24 hours.
