Parametric programming of the control lines/cables of the
COM 2/COM 3 interface
The operation of the control lines/cables is implemented with the
“ComControl” module. This function only serves the DTR, DSR and
DCD interface lines of the XIOC-SER hardware interface module.
The ERROR LED available on the module is also operated via this
module and controlled with the TRUE command. If the respective
interface lines are parameterized with TRUE, read/write access is
possible.
Parametric programming of the interface
In the “ComSettings” module the complete interface parameters
of the COM 2 or COM3 interface are deposited and stored. These
parameters are activated by the call up of the module and
assigned to the respective hardware interface.
