RS232 interface in transparentmode (COM 1/2/3)10/10 MN05003004Z-EN62Parametric programming of the control lines/cables of theCOM 2/COM 3 interfaceThe operation of the control lines/cables is implemented with the“ComControl” module. This function only serves the DTR, DSR andDCD interface lines of the XIOC-SER hardware interface module.The ERROR LED available on the module is also operated via thismodule and controlled with the TRUE command. If the respectiveinterface lines are parameterized with TRUE, read/write access ispossible.Parametric programming of the interfaceIn the “ComSettings” module the complete interface parametersof the COM 2 or COM3 interface are deposited and stored. Theseparameters are activated by the call up of the module andassigned to the respective hardware interface.Figure 88: Parametric programming of the control lines of the COM 2 and COM 3 interfaces and the ERR-LEDFigure 89: Interface parameter of the COM 2 or COM 3 interface
