Transfer block
With this function you can transfer new or existing logic and data
blocks to the user memory of the CPU.
If a block already exists in the user memory of the CPU, it is declared
invalid and the new block becomes valid.
Delete block
With this function you declare a logic or data block in the user
memory as invalid.
The space taken up by such blocks is released and can be used again.

Program Test
Start/stop
When you use the START and STOP PG functions, operating the PG
corresponds to manual operation.
You can put the programmable controller into the STOP mode by
calling the STOP function while the controller is in the RUN mode.
PGSTP is marked in the control bit display. In multiprocessor
operation, the HALT control bit is set for the other CPUs.
You exit the SOFT STOP status with a COLD RESTART or WARM
RESTART. In the single processor mode, the CPU exits the stop
mode. In multiprocessor operation, the restart type is registered
initially (the NEUDF or WIEDF control bit is set). However, the CPU
stays in the soft STOP mode until all CPUs are initialized for
multiprocessing. With the next operation "system start" you can start
the programmable controller. This corresponds to switching the
coordinator switch to RUN.
You can call the START PG function in the multiprocessor mode to
select the restart type you want for all the CPUs you are using. After
that, you can start the programmable controller with the last CPU.
