$0 = 10


$1 = 1

CALL 1($0 = 0)







Fig. 3-14-9 Execution process of Screen Open Macro


When CALL 1 is executed, it means that Sub-Macro 1 is called and executed. After
executing Sub-Macro, the system will continue to execute Sceen Open Macro till it ends.
At this time, 0 = 0 and $1 = 1.

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. program 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.
