4.3.7 Ethernet
Most control systems are equipped with an integrated Ethernet connection. Since Ethernet is much
more powerful than most fieldbuses, it is recommended to access the control system via Ethernet
(and not via the lower-level fieldbus system).
This option has been described in the previous bus-specific chapters. There is no general possibility
of accessing optional field devices via Ethernet because Ethernet only describes the physical bus
features, but not the transmission protocol. Depending on the field device to be addressed, different
Ethernet protocols are required.
Lenze supports the RFC1006 Ethernet protocol which is based on TCP/IP and is supported by many
control system manufacturers. Control systems by the following manufacturers can be accessed via
RFC1006:
• Siemens S7-300/400
• VIPA
• SAIA
In addition, drivers for access to the following control systems are available:
• Industrial PCs (PC-based Automation): 3S Smart Software Solutions (CoDeSys V2.x)
• Controller (Controller-based Automation): 3S Smart Software Solutions (CoDeSys V3.x)
