Design

2.1 General

This software connects a CANopen network to the local backplane modules. The Gateway

transports commands and responses to and from the CANbus. It scans the LDM modules for

their status and then transmits this status information continuously to the CAN controller.

2.2 Backplane

handling

The Gateway must continuously scan the backplane modules. It keeps track of which

modules are present and those that are not. The Gateway communicates with 4 levels of

priority on the backplane.

The highest priority communication is initiated on direct commands from the CAN controller

either by accessing a SDO or by using RPDO3.

The second highest priority is given to LDM modules in the final filling stage. The Gateway

reports the end of filling for each module with a TPDO2 containing the module number,

module status, and for example the dosed weight.

The third priority is the normal module scan. The Gateway continuously transmits TPDO1

with the status information for each module.

At a very low priority the Gateway looks for backplane modules that aren’t recorded as

active, in order to re-establish communication with modules that may have been restarted to

recover from failure.

The Gateway always informs the CAN controller when a module fails, or comes back online.
