Take HMI0 as example and the mask relationship is shown as below:
LW.B 9400.0
LW.9264~9279

Mask System Prompt Information
NB-Designer provides the system information mask function which is controlled by the special
registers LW9296 (read/write) and each bit corresponds to one piece of system error
information, and the system error information will be masked when the corresponding bits are
set to ON. For example, LW.B9296.2 corresponds to the prompt information "PLC No
Response".
Note: LW.B9296.2 must be set to "Set On when Window Open".
Take Mask of "PLC No Response" as example
(1) Create one project, and connect NB5Q-TW00B with SIMENS S7-200 for communication.
(2) Place one Number Input component VW0 (One register in SiemensS7-200) and one Bit
State Setting component with the address of LW.B9296.2 and Type of "Set On when
Window Open" in HMI Edit Window.
(3) Actually, HMI0 is not connected with Siemens S7-200 PLC. The prompt information of "PLC
No Response" should appear before, but now the system error prompt information doesn't
appear for the LW9296 mask function.

How to clear RW area for recipe saving
Clear the address of related register of RW
(1) Set LB9130 (system register of HMI) to ON to trigger "Clear RW".
(2) Set LW9260 occupying double words, and set the start address for RW clearing.
(3) Set LW9262 occupying double words, and set the word length for RW clearing.
