(three lines of macro commands), when background macro is executed, HMI will first read 25 element
addresses and then execute one line of background macro in order.
„ Clock Macro
There is only an initial Macro in a program or a machine. Similar to Screen Cycle Macro, it can be
executed repeatedly for a specified period of preset clock time. The user can set Clock Macro Delay
Time, i.e. the delay time every time between the end and the restart of Clock Macro in Standard tab of
Configuration dialog box (See Fig. 4.1.3). The system default setting is 100ms.
