Weilun Tong macro is a programming language for human-computer interface interaction development, which is based on a programming language developed by Microsoft VB in the early days, macro provides some additional functions you need in addition to EBPro applications, macro is widely used, almost can realize most of the functions of PLC control.

Commonly used logic control, start-stop circuit; Logical operations, four-rule operations, string processing. Communication with thermostats, frequency converters, etc., can be achieved with macros.

Although the macro can be controlled logically, the touch screen itself does not have the output function of the PLC body, so it cannot directly control the device, and still needs to communicate with the PLC for output control. In this way, coupled with the communication time, the output lag is certain, so when the real-time requirements are relatively high, the practical application of the logic control of macros is of little significance.

The advantage of macros is that some functions that are not available in applications can be achieved with the help of macros, such as the processing of some strings, interface switching, etc.
