Methods and nodes for facilitating communication between a tool server and a plurality of tool controllers in a work tools communication system

A method performed by a work tools communication system for facilitating communication between a tool server and a plurality of tool controllers of the work tools communication system, the tool server being connected to the plurality of tool controllers, the tool controllers being further adapted for communication with the work tools connected to the tool controllers, the method comprising:

• sending, from the tool server to a first of the plurality of tool controllers, a message relating to control of at least one work tool connected to the first tool controller, the message comprising a destination address of the first tool controller and a requested action to be performed by the first tool controller;
• receiving, by the first tool controller, the message sent by the tool server, based on the destination address;
• analysing, by the first tool controller, the message to detect the requested action;
• and
• controlling, by the first tool controller, the at least one work tool connected to the first tool controller according to the detected requested action,
• wherein the message further comprises a header part and a payload part, the header part comprising the requested action and the payload part comprising details of the requested action, and wherein the payload part is divided into a plurality of data nodes, each data node comprising a type of data field and a data value field.

A method performed by a tool controller of a work tools communication system for facilitating communication with a tool server of the work tools communication system, the tool controller being adapted for communication with work tools connected to the tool controller, the method comprising:

• receiving, from the tool server, a message relating to control of at least one work tool connected to the tool controller, the message comprising a destination address of the tool controller and a requested action to be performed by the tool controller, the message being received based on the destination address, wherein the message further comprises a header part and a payload part, the header part comprising the requested action and the payload part comprising details of the requested action, and wherein the payload part is divided into a plurality of data nodes, each data node comprising a type of data field and a data value field;
• analysing the received message to detect the requested action;
• and
• controlling the at least one work tool of the tool controller according to the detected requested action.

A tool controller of a work tools communication system for communicating with a tool server of the work tools communication network, the tool controller being adapted for communication with work tools connected to the tool controller, the tool controller comprising a processor and a memory, said memory containing instructions executable by said processor, whereby said tool controller is operative for:

• receiving from the tool server, a message relating to control of at least one work tool connected to the tool controller, the message comprising a destination address of the tool controller and a requested action to be performed by the tool controller, the message being received based on the destination address;
• analysing the received message to detect the requested action;
• and
• controlling the at least one work tool of the tool controller according to the detected requested action,
• wherein the message further comprises a header part and a payload part, the header part comprising the requested action and the payload part comprising details of the requested action, and wherein the payload part is divided into a plurality of data nodes, each data node comprising a type of data field and a data value field.

A computer program comprising computer readable code, which when run in a tool controller of a work tools communication system for communicating with a tools server of the work tools communication system, causes the tool controller to perform:

• receiving, from the tool server, a message relating to control of at least one work tool connected to the tool controller, the message comprising a destination address of the first tool controller and a requested action to be performed by the first tool controller, the message being received based on the destination address;
• analyzing the received message to detect the requested action;
• controlling the at least one work tool of the tool controller according to the detected requested action,
• wherein the message further comprises a header part and a payload part, the header part comprising the requested action and the payload part comprising details of the requested action, and wherein the payload part is divided into a plurality of data nodes, each data node comprising a type of data field and a data value field.
