7-2-15 UM Area Allocation
This operation is used to allocate part of the UM Area for use as expansion DM. It
can be performed in PROGRAM mode only. Memory allocated to expansion DM
is deducted from the ladder program area.
The amount of memory available for the ladder program depends on the amount
of RAM in the CPU Unit. About 15.2 KW of memory is available with the16-KW
RAM and about 31.2 KW is available with the 32-KW RAM.
This operation cannot be used to allocate UM to the I/O comment area. UM can
be allocated to the I/O comment area only with a host computer equipped with
SYSMAC Support Software.
