6.3 Startup
6.3.1 OB 100, OB 102 - Complete/Cold Restart - Startup
On a restart, the CPU sets both itself and the modules to the programmed initial state,
deletes all not-latching data in the system memory, calls Startup OB and then executes
the main program in OB 1. Here the current program and the current data blocks gener-
ated by SFC remain in memory.
A distinction is made between the following types of startup:
n OB 100: Complete restart
n OB 102: Cold restart
The CPU executes a startup as follows:
n after PowerON and operating switch in RUN
n whenever you switch the mode selector from STOP to RUN
n after a request using a communication function
(menu command from the programming device)
Even if no startup OB is loaded into the CPU, the CPU goes to RUN without an error
message.
The following table describes the start information of the startup OB with default names of
the variables and its data types:
