Function 1, 2: Signals synchronized actions to / from Channel
Synchronized actions can be disabled or enabled by the PLC.
The data area is stored on the user interface in DB21, ... .DBB300 ...307 (to channel) and
DB21, ... .DBB308 ...315 (from channel). The parameter "S7Var" is not evaluated for this
function, but must be assigned an actual parameter (see call example). The data are
transferred to/from the NC as soon as FC21 is processed.
