Start Up 2-5Establishing A ConnectionWith EtherNet/IPThere are three methods for configuring the embedded EtherNet/IPadapter’s IP address:• Adapter Rotary Switches – Use the switches when working on asimple, isolated network (for example, 192.168.1.xxx) that has otherproducts with switches to set their IP addresses, does not need to beaccessed from outside the network, and you prefer a simplified nodeaddressing method. The three adapter switches are read when the drivepowers up, and represent three decimal digits from top to bottom (seeFigure 2.2). If set to a valid address (001-254), the adapter will use thatvalue as the lower octet of its IP address (192.168.1.xxx, where xxx =rotary switch settings), along with a subnet mask of 255.255.255.0 andthere will be no gateway configured. Also, the setting for adapter P36[BOOTP] is automatically ignored.See Figure 2.2 and its accompanying table for all possible switch settingsand their related descriptions.Important: When using the adapter rotary switches, set the IP addressbefore power is applied because the adapter uses the IPaddress it detects when it first receives power.• BOOTP Server – Use BOOTP if you prefer to control the IP addressesof devices using a server. The IP address, subnet mask, and gatewayaddresses will then be provided by the BOOTP server.• Adapter Parameters – Use adapter parameters when you want moreflexibility in setting up the IP address, or need to communicate outsidethe control network using a gateway. The IP address, subnet mask, andgateway addresses will then come from the adapter parameters you set.Important: Regardless of the method used to set the adapter’s IP address,each node on the EtherNet/IP network must have a unique IPaddress. To change an IP address, you must set the new valueand then remove and reapply power to (or reset) the adapter.Figure 2.2 Setting the IP Address SwitchesHundredsPositionTensPositionOnesPosition323241324141505050696796798878PowerFlex 750-Series User Manual – Publication 750-UM001C-EN-P – September 2009
