Input data for slot 30*
* = The amount of input data for each module is based on the configuration of each I/O module done as part of the 1769-ADN configuration. Note that if an I/O
module is configured to have 0 words of input data, then there are no input data words for that module in the 1769-ADN’s input image.
V1 = Data invalid from slot 1 (1 = invalid data)
V2 = Data invalid from slot 2
V3 = Data invalid from slot 3
...
V30 =Data invalid from slot 30
where 1 = data invalid or a module error is detected; 0 = data valid, no module error
NS = Node address switch changed
where 1 = node address switch changed since power-up
X = Reserved
