Problems solved by technology

However, protocol conversion circuits are usually active circuits that require external electrical power and signal processing, which increases the power requirements, cost and complexity of the control network implementation, and may also add processing delays to the communication
This is especially detrimental to industrial control environments where fast-acting real-time or deterministic communications may be required

Abstract

The present invention comprises a communication module. A communication module used in a control network comprises: an interface circuit configured to realize communication with an external device; a communication device configured to communicate with the external device through the control network by means of communication with the interface circuit; a coupling device configured to mechanically couple the control module to an adjacent control module and provide data connection between the communication device and the adjacent module; and an electrical isolation in data connection located between the communication device and the coupling device.

Description

technical field [0001] The present invention relates to, but is not limited to, the implementation of communication modules, communication components and communication networks such as control modules, control components and control networks in industrial control environments. Background technique [0002] Communication applications, such as industrial control applications, can be harsh environments for the transmission of communication signals over communication networks. This is partly due to the amount of electromagnetic noise in the environment. Therefore, communication protocols and transmission media over which communication signals are transmitted must generally be robust so that they can withstand the potentially damaging effects of electromagnetic interference. Communication robust to such noise usually requires high transmission power or resilient signaling techniques. Additionally, in some environments, the distances covered by communication signals may be large...
