Channel switch for coupling of two redundant devices to one communication line

  • For protocol converters in redundant operation, maximum uptime is ensured with the hot standby method. This means only one of the two devices is active at any time. The passive device monitors the active one and if the active one fails, the passive one automatically steps in and resumes communication.
    The currently active protocol converter then sends a defined signal string to the channel switch initiating the switchover.
    All communication in control and monitoring direction is then run by the second protocol converter.

    Please note that in monitoring direction information is transmitted to both the active and passive protocol converters, irrespective of the position of the channel switch.
