LZF (Runtime Errors)
A runtime error occurs when the CPU detects an error during the
execution of a STEP 5 operation.The operation that causes the
runtime error is
not executed. (Exception: opening a non-existent
data block DB/DX
). If there is an LZF organization block, this is
called. The interrupted user program is then continued from the next
operation after the operation that caused the error. If no LZF-OB is
loaded, the CPU goes to the STOP mode.
The following runtime errors are possible. In each case, the named
error OB is called:
LZF - calling a block that
is not loaded (OB 19)
If a block is called or opened in the user program and this block does
not exist, the system program automatically detects an error. This
applies to all block types and is true for conditional and unconditional
calls.
If the system program detects the call or opening of a block that is not
loaded, it calls organization block
OB 19, if it is loaded. In OB 19,
you can specify how the CPU should proceed.
If you have programmed OB 19, it is called and processed following
which the interrupted STEP 5 program is continued at the next
operation unless OB 19 contains a stop operation. If, on the other
hand, you have not programmed OB 19, the CPU goes into the STOP
mode when a block that is not loaded is called or opened.
