Ethernet gateways
This chapter describes the following samos®PRO gateways:
• EtherNet/IP gateway (SP-EN-IP)
• Modbus TCP gateway (SP-EN-MOD)
• Profinet IO gateway (SP-EN-PN)
5.1
Common features of the Ethernet gateways
5.1.1
TCP/IP configuration interface
The samos®PRO Ethernet gateways offer a TCP/IP configuration interface which allows the
configuration of the samos®PRO System over Ethernet TCP/IP. This runs parallel to the
Ethernet TCP/IP or other Ethernet protocols.
Do not connect to the samos®PRO system via the RS-232 and the Ethernet interface
at the same time!
The samos®PRO system can only communicate with one instance of the samos®PLAN at one
time. Connecting to the samos®PRO system using multiple instances of the Designer, either
on a single PC or multiple PCs, may result in inconsistencies of the configuration and the
diagnostics as well as in operational errors. This applies to both RS-232 and Ethernet connections equally.
WA RNING
In order to configure a gateway for TCP/IP configuration for the first time, perform the
following steps:
Step 1: Assign an IP address
 Connect a PC or notebook to the RS-232 interface of the SP-SCON.
 Power on the samos®PRO System.
 Open the samos®PLAN configuration tool installed on the PC and load the hardware configuration including the gateway.
 If your project is online, click on the Disconnect button to go offline.
 Click on the Gateway button above the main window and select the desired gateway.
 Click on Gateway configuration on the left hand menu. The following dialog appears:
