The Set/Reset Function Block either holds
an output ON (set) or releases the output
OFF (reset.) Priority can be given to either

AL-PCS/WIN-E software for Alpha Series
Controllers. When control bit N04 is ON, it
is possible to control the displayed User
Screen.
The Connect function block is an internal
device used to show the memory used by
input bits, system bits, AS-interface bits,
0 0 0
and the operation keys. No function block
I O
appears on screen or is shown as being
used in the "Memory Configuration Usage"

dialog box. The purpose is only to calculate
the memory that is used by the bits listed
above.
