Aborting during operation
The File Memory Read operation is used to read user program data (UM)
stored in the FM area and transfer it to a specified area in RAM Program
Memory, or to read user data (IOM) in the FM area and transfer it to one of
the CPU data areas. The data is read and transferred in blocks of 128 words.
When reading data to be transferred to program memory, reading begins at
the specified FM start block. Reading and block transfer end when either the
first END(01) or non-UM (i.e., CM or IOM) FM block is encountered, or when
the RAM user program memory area to which the data is being transferred
overflows.
When reading data for a data area, reading begins at the specified FM start
block and continues to the end. If a non-IOM block is encountered, an error
message will be displayed and transfer will not be possible. When transfer-
ring data to the DM area, you must specify the number of blocks to be read
and transferred.
