AS-Interface Digital I/O module -- In this week's episode, Tim explains the data concerning the outputs, profiles, data bit layout, and parameter bits for AS-Interface module VBA-4E4A-G11-ZAJ/EA2L-F. --Typical AS-Interface modules with electronic outputs are sourcing 24 VDC plus. --Depending on the "power source," digital outputs are powered from AUX or from AS-Interface. --It is important to look at the total output current and watch for any restrictions. --Profiles specify the "function" of a module; they are important in case a failed module must be replaced. --Data bit layout is important since a PLC programmer needs to know where in the PLC map an input shows up and which PLC bits control an output. --Parameter bits give the programmer the ability to modify the behavior of a module.
