11 Assignable IO Details
Introduction
The Gen IV controller supports assignable I/O.
Buses
The controller is divided up into buses. Each bus has a set of inputs and a set of outputs. Currently the
controller supports the following buses.
Bus Number
Bus
1
Physical I/O
2
Fieldbus (Anybus module) I/O
3
Modbus TCP
4
Ethernet/IP
All assignments have a bus, element, and bit configuration to define its location in the system. The bus
value needs to be set from the list above. The element and bit define the location in the bus. The first
element on the bus is 0 and goes up the last legal element for the given bus. The bits in each element is
referenced from 0(LSB) to 31(MSB).
Inputs
All input assignments have a Bus, Element, and Bit configuration to define its location in the system.
Along with the basic configuration many also have other configuration(s) that allow its behavior to be
modified to suit the application.
