Language interface

At a glance The language interface defines all the data that can be read or modified by the application program. The data is implicit and periodic (%Q, %QW, %I, %IW) when it is updated automatically by the PLC task. It is explicit and not periodic (%MW) when it is updated by the program after execution of the READ_STS or READ /

WRITE_PARAM functions.

It is possible to associate with each word or bit a symbol that can be used by the application program (see PL7 reference manual). A table of symbols has been predefined. They can be assigned to the module data (see PL7 Reference Manual).
