Mask System Prompt Information
NB-Designer provides the system information mask function which is controlled by the special
memories 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 Place Bit Button component and others in the screen which should be being masking of error display and
specify [Set to ON when screen is open] for Type and specify LW.B9296.2 to On.
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 memory in SiemensS7-200) and one Bit
Button component with the address of LW.B9296.2 and Type of “Bit Button” in Edit Window.
(3) Actually, PT0 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.
