Analog output modules -- Tim and Helge again talk about AS-Interface data sheets. More specifically, they are focusing on the data that is specific to analog output modules, such as the G11 AS-Interface module VBA-4A-G11-I/U-F. --The voltage and current range specifies what kind of output signals the modules can generate.  While 0 V -10 V and 4 mA to 20 mA is normal, it is also possible to output current signals down to 0 mA. --The supply section specifies whether the outputs are powered from the AS-Interface yellow cable or the back AUX cable.  The second option is, of course, able to provide a lot more current. --Parameter bits are again used to modify the operation.  Frequently, the parameter bits are used to configure the module watchdog. --On some modules, a DIP switch is used to lock in the type of output; either current or voltage.
