Clear Flag of History Buffer
HMI history buffer (Fig. 5.1.2) can be cleared by the external controller, i.e. PLC. Once the control flag
is triggered to ON (Bit 0 ~ Bit 11 is set to ON), it will clear HMI history buffer ONCE. This flag needs be
set to OFF and then ON if the user wants to trigger again.

Control Flag for Changing Recipe Number
There are two kinds of methods for changing and calling recipe number. One method is to use HMI
internal register, RCPNO directly. RCPNO is the internal system register used for designating recipe
number. The other method is to use
Recipe Control Register (RECR) (Dn+5). When the user wants to
change HMI recipe number, i.e. RCPNO value through control block settings, first, it needs to write
recipe number (N) into Designated Recipe Number Register (RBIR) (Dn+6, please refer to the
explanation of
Register for Designating Recipe Number (RBIR)
) and use this control flag to trigger Bit 0
of Dn+5 to be ON. After setting, RCPNO will be changed to N automatically. This flag needs be set to
OFF and then ON if the user wants to trigger again.
Control Flag for Reading Recipe
The user can change the recipe value of PLC by triggering this control flag (Bit 1 is set to ON). Before
reading a recipe from PLC, the user should designate the recipe number (N) first (Please refer to the
section “
Control Flag for Changing Recipe Number
”). Then, trigger this control flag to ON (Bit 1 is set to
ON). After setting, the recipe will be read from PLC and stored in designating area of HMI. This flag
needs be set to OFF and then ON if the user wants to trigger again.
