An industrial mission critical networking communication device is adapted from a wired industrial networking communication device to provide wireless capabilities. Accordingly, the PHY of the wired device, that is communicatively connected to a first microcontrollers, is replaced by a second microcontroller. The second microcontroller is adapted to communicate with the first microcontroller using a serial adaptation layer to ensure that the original communication interface between the PHY and the first microcontroller is maintained. The second microcontroller is further adapted with at least capabilities of wireless communication to allow for wireless communication based on a predetermined protocol, for example, the wireless IO-Link® protocol.

Reducing signal interferences in critical mission wireless communication system

A method for securing communicating with a human machine interface (HMI) terminal over a mission critical wireless link (MCWL) link is provided. The method includes sending, by a MCWL node, a connection request to the HMI terminal; upon receiving an acknowledge from the HMI terminal, authenticating the HMI terminal; and upon authentication of the HMI terminal, establishing a secure connection channel is between the MCWL node and the HMI terminal, wherein commands to at least control the MCWL node are sent from the HMI terminal over the secure connection channel.

Human machine interface for mission critical wireless communication link nodes

A communication method between a master and a device, the master transmits in a subcycle a received condition message (RCM) for an immediately prior subcycle, wherein the RCM is an ACK when a transmission from the device in the preceding subcycle was correctly received and the RCM is a NACK when a transmission from the device in the preceding subcycle was not correctly received, comprising: including in each transmitted condition message a current priority data acknowledgement flag (CPDAF), the CPDAF being transmitted set in each condition message for each subcycle of an offset cycle after the master correctly received in a current cycle a priority data message, the offset cycle being defined as the second and subsequent subcycles of a current cycle and the first subcycle of a next cycle, the CPDAF being transmitted as cleared otherwise.

A method for hub for interfacing between a wireless mission critical communication link (MCCL) and a wired MCCL. The hub includes a wired interface a providing a physical layer connectivity to the wired MCCL; a plurality of ports coupled to the wired interface; a wireless interface providing a physical layer connectivity to the wireless MCCL; and a processor; and a memory containing instructions that, when executed by the processing circuitry, configure the hub to: receive a signal from a primary device through the wireless MCCL; determine a wireless communication cycle of the primary device; determine a wired communication cycle of a secondary device, wherein the secondary device is connected via the wired MCCL; synchronize a start time of the wired communication cycle to a start of the wireless communication cycle; and send the received signal to the secondary device at the synchronized start time of the wired communication cycle.

A novel and useful acknowledgement and adaptive frequency hopping mechanism for use in wireless communication systems such as IO-Link Wireless. One or two additional acknowledgement bits are added to packet transmissions. One is a current acknowledgment bit which indicates whether a packet was successfully received anytime during the current cycle. The second bit is a previous acknowledgment bit which indicates whether packets were received successfully anytime during the previous cycle. An adaptive hopping table is constructed using a greedy algorithm which chooses frequencies with the best PER for transmission of higher priority packets, while equalizing the PER products across cycles. A last resort frequency mechanism further improves transmission success by switching to a better performing channel for the last subcycle when previous attempts to transmit a high priority packet have failed.
