B-4 Using the ASCII Modules with the ControlLogix System Application Examples

Reading Data from the ASCII Modules into ControlLogix

For this example, the advanced mapping feature in RSNetWorx for

DeviceNet was used to separate the header bytes into their own data

Local:1:I.Data[0], the status byte is in Local:1:I.Data[1], and the length

is in Local:1:I.Data[3]. The ASCII data starts in Local:1:I.Data[4].
