  • Page 34: Gateway With Shared Memory

    The Z-KEY / Z-KEY WIFI can be configured with up to 500 tag (1 tag = 1 variable that can be composed by one or two Modbus registers), these values are stored into a shared memory that can be accessed from Ethernet /Wifi and/or from Serials.

By this port the Modbus RTU Slaves (connected to the Z-KEY Modbus Master port) values are available for the PLC.

  • Page 38: How It Works

    A lot of PLCs have the limitation that only the Modbus Master protocol is implemented. When values from the Modbus Slaves must be read/write from the PLC and also from a SCADA/Datalogger, the Z-KEY / Z-KEY WIFI can be configured with one serial port in modbus slave (connected to the PLC modbus master port)

    Modbus Slaves must be shared with another PLC/SCADA/DATALOGGER etc.. the Z-KEY can be configured in Gateway mode with the 2 ports in Modbus Slave. In this way the two PLCs and the Ethernet Clients can freely write/read the Z-KEY Shadow memory for data sharing:...
