Note:
*1 Number of bytes used = 19 + 1 x (Characters in equation)
*2 Number of bytes used = 8 + 4 x (Number of time switches)
*3 Number of bytes used = 30 + 1 x (Characters in equation)
*4 Number of bytes used is decided by the displayed item.
*5 Number of bytes used = 32 + 3 x (Number of screen)
*6 Number of bytes used = 12 + 1 x (Characters in E-Mail address)
Retentive
Set/Reset
[RSR]
The Set/Reset Function Block either holds
an output ON (set) or releases the output
OFF (reset.) Priority can be given to either
input pin if both inputs have been
energised. The default priority setting is
dedicated to the reset input pin. When the
power is turned OFF the function block will
use the last set or reset operation to control
the output.

Control
Display
[CDP]
The Control Display Function allows the
user to control the LCD image screens. The
function block can only be set in
AL-PCS/WIN-E software for Alpha Series
Controllers. When control bit N04 is ON, it
is possible to control the displayed User
Screen.
*5 6.35
Connect
[ _B ]
The Connect function block is an internal
device used to show the memory used by
input bits, system bits, AS-interface bits,
and the operation keys. No function block
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.
