Input Structure
The controller receives input I/O by reading input data from an input
structure in the 1756-DNB scanner module. The scanner module receives
input data from DeviceNet modules and delivers a copy of these values to the
controller. The input structure consists of one 32-bit status register and a
variable size 32-bit array of up to 124 words for input data. The 32-bit status
register reflects the current state of several key module-level operational
parameters.
The input structure consists of these data elements.
Input Structure Element Data Type
module status register 1 x 32-bit register
input_data 123 x 32-bit variable size data array
