CONTROLLER LOGICAL STRUCTURE
The controller is internally organized as a set of function blocks, which can be individually
configured and arbitrarily connected together to achieve the required system functionality, see
Figure 3.
Figure 3. The Controller Logical Block Diagram
Each function block is absolutely independent and has its own set of configuration parameters,
aka setpoints. The configuration parameters can be viewed and changed through CAN bus
using Axiomatic Electronic Assistant
®
(EA) software or over Modbus interface.
The
Universal Input
function block presents the controller physical input channels. This
function block can measure multiple physical parameters.
The J1939 CAN interface is presented by the
CAN Input Signal, CAN Output Message
and
J1939 Network
function blocks. The
CAN Input Signal
functional blocks are used to receive
CAN signals transmitted on the CAN bus. They have one signal output, which is updated once
the signal is received. The
CAN Output Message
function blocks are used to transmit CAN
signals on the CAN bus. Each CAN message can hold up to ten individual CAN output signals,
receiving data from their own signal inputs.
