Input Module’s Input Image
The input modules’ input image file represents data words and status bits.
Input words 0 to 3 hold the input data that represents the value of the analog
inputs for channels 0 to 3. These data words are valid only when the channel is
enabled and there are no errors. Input words 4 and 5 hold the status bits. To
receive valid status information, the channel must be enabled.
For example, to obtain the general status of channel 2 of the analog module
located in slot 3, use address I:3.4/2.
TIP
The end cap does not use a slot address.
I:3.4/2
