NOTE
When editing any macros, please pay close attention to the logicality of macro command,
especially the usage of loop and program. If the user write an infinite loop (i.e. pro

ram cannot
be ended) in the macro or write a program which will not be executed until some certain
condition is satisfied, it may make HMI work abnormally. Therefore, it is recommended that the
user should use simulation function to verify the macro and check if HMI operation is correct or
not after macro editing is completed.
