Following it shows operating characteristics of the SRW01-ETH smart relay using the for PROFINET communication.
8.1
IP ADDRESS CONFIGURATION
In a PROFINET network, IP address programming is usually done through the network itself, instead of being locally
programmed in the product. In this case, you must program in the P0760 to option 2 (DCP). With this option, no local
product configuration will be used - IP address, subnet mask, DHCP or gateway. Configuration of these properties
must be received over the network using DCP commands. It is also possible to set the addressing switches to ’FF’
position, so that the IP address configuration is not made locally, only via network via DCP. To set the IP address
locally on the product - as well as other relevant parameters - you must use the parameters P0760 to P0769.
8.2
STATION NAME CONFIGURATION
In a PROFINET network, each equipment has a different Station Name, which is used to identify the equipment in the
network.
The two addressing switches, next to SRW01-ETH Ethernet connectors, allow you to program how to configure
the Station Name, where the switch
Ê
represents the most significant digit and the switch
Ë
represents the less
significant digit.

Configuration
00h
Station Name: do not program the Station Name, and this configuration
must be done via network using the DCP protocol. Once programmed,
the Station Name value is saved to non-volatile memory, and remains
programmed even when the product is turned off.
IP address: IP address settings are made using the parameters P0760
to P0769.
01h ... FEh
Station Name: the combination of switches 1 and 2 form the value to
configure the Station Name suffix. In this case, when powering the pro-
duct, it will assume the Station Name ”SRW01-ETH-XY”, with ’X’ and ’Y’
being the value of switches 1 and 2 respectively (numbers ’1’ through ’9’
and letters ’A’ to ’F’).
IP address: IP address settings are made using the parameters P0760
to P0769.
FFh
Station Name and IP Address are not programmed locally, and all confi-
guration must be done via network using the DCP protocol. Once pro-
grammed, the values are saved in non-volatile memory, and remain pro-
grammed even when the product is turned off.
