# MacroTen ActiveX control

The MacroTen ActiveX control provides the system with the ability to read ten analog values and write the values to ten assigned tags. The input values, Read connections, can be a constant, tag, tag placeholder "{#1}", or an expression built with tags and tag placeholders.

When triggered, the MacroTen ActiveX control writes the value of each Read connection to the corresponding Write connection. For example, Read01 is written to Write01, Read02 is written to Write02, ..., Read10 is written to Write10.
