Communication module, communication system, and method for the communication module

A communication module comprising:

• a first communication interface, a second communication interface, and a processing unit,
• wherein the first communication interface is configured to receive an instruction message according to a first communication protocol, wherein the instruction message represents a predefined reference instruction,
• wherein the communication module is configured to detect an uninterrupted idle time during which the communication module does not receive a message via the first communication interface, and
• wherein the processing unit is configured, in response to the uninterrupted idle time exceeding a predefined dead time, to control the second communication interface such that the second communication interface transmits a command message according to a second communication protocol, wherein the command message represents the reference instruction.

A communication system comprising:

• a first device, a communication module, and a second device,
• wherein the communication module comprises a first communication interface, a second communication interface, and a processing unit,
• wherein the first communication interface is configured to receive an instruction message according to a first communication protocol, wherein the instruction message represents a predefined reference instruction,
• wherein the first device comprises a third communication interface, that is configured to receive and transmit messages according to the first communication protocol,
• wherein the first device is configured to transmit the instruction message via the third communication interface to the first communication interface of the communication module,
• wherein the communication module is configured to detect an uninterrupted idle time during which the communication module does not receive a message via the first communication interface,
• wherein the processing unit is configured, in response to the idle time exceeding a predefined dead time, to control the second communication interface such that the second communication interface transmits a command message according to a second communication protocol, wherein the command message represents the reference instruction,
• wherein the second device comprising a fourth communication interface, and
• wherein the second device is configured to create and transmit a response message via the fourth communication interface to the second communication interface of the communication module.
