PNOZmulti with fieldbus module
The PNOZmulti system in the example consists of the following modules:
}
PNOZmulti base unit PNOZ m B1
}
PNOZmulti input/output module PNOZ m EF
}
PNOZmulti fieldbus module with Ethernet interface
Description:
The PNOZmulti system has 2 Ethernet modules in networks that are independent of each
other.
}
Base unit in protected network:
The connection to the configuration tool PNOZmulti Configurator is created via the Ether-
net interfaces at the base unit. The project is changed via this connection and transferred
to the PNOZmulti. This connection is protected. The PNOZmulti base unit is in the protec-
ted network. Access to the base unit is only performed with the VPN client via the Secur-
ityBridge.
}
Fieldbus module in unprotected network:
Via the Ethernet interfaces of the left-hand side fieldbus module, process date are ex-
change in a control system. This module is in an independent network. The connection to
the control system is not protected. The fieldbus module is in the protected network.
