Introduction to COM-LINK The COM-LINK is a point-to-point connection via a serial
interface. This interface connection allows the reading of
input/output states as well as the reading and writing of
marker ranges. This data can be used for setpoint entry or for
display functions. The stations of the COM-LINK have
different functions. The active station controls the entire
interface. The remote station responds to the requests of the
active station. The remote station cannot detect whether the
COM-LINK is active or whether a PC with CL-SOFT is using
the interface.
