Initial Setup and Configuration
Proper setup involves assigning a unique IP address to the 1734-AENTR adapter‚ utilizing either thumbwheel switches‚ BootP‚ or DHCP methods for network connectivity.
Default settings enable automatic IP acquisition‚ simplifying initial integration into existing EtherNet/IP networks for streamlined communication.
Default IP Address Setting (999)
Upon initial power-up‚ the 1734-AENTR communication module is pre-configured with a default setting of “999” on its thumbwheel switches. This deliberate configuration isn’t intended for direct network communication; instead‚ it’s a crucial step to facilitate automatic IP address acquisition.
Setting the thumbwheels to 999 instructs the adapter to actively listen for an IP address to be assigned via either the BootP (Bootstrap Protocol) or DHCP (Dynamic Host Configuration Protocol) services available on the network. This eliminates the need for manual IP address entry during the initial setup phase‚ simplifying the integration process.
This default setting is particularly beneficial in environments where centralized IP address management is employed‚ allowing the network infrastructure to dynamically allocate an appropriate IP address to the adapter. It’s important to note that while in the “999” setting‚ the adapter won’t respond to direct network requests until an IP address is successfully obtained.
After acquiring an IP address‚ the adapter will function as a standard EtherNet/IP device‚ enabling communication with PLCs and other network components.
IP Address Configuration Methods
The 1734-AENTR adapter offers multiple methods for configuring its IP address‚ providing flexibility to suit various network environments and user preferences.

Manual configuration involves setting the desired IP address directly on the adapter using the thumbwheel switches. This method is suitable for static network environments where IP addresses are pre-defined. However‚ it requires careful attention to ensure the address is unique and compatible with the network’s subnet mask.
BootP configuration allows the adapter to obtain an IP address from a BootP server on the network. This method simplifies IP address management‚ particularly in larger networks.
DHCP configuration is another automatic method‚ utilizing a DHCP server to dynamically assign an IP address to the adapter. This is the most common approach in modern networks‚ offering centralized IP address management and automatic lease renewal.
Using Thumbwheels
The 1734-AENTR adapter allows for direct IP address configuration via onboard thumbwheels‚ offering a straightforward method for static IP assignment. By default‚ the adapter ships with the thumbwheels set to ‘999’‚ enabling BootP or DHCP discovery. To manually set an IP address‚ each thumbwheel must be adjusted to represent a digit of the desired address.
Carefully consult the adapter’s documentation to understand the specific thumbwheel encoding scheme. Incorrect settings can lead to communication failures or IP address conflicts. Ensure the selected IP address is within the network’s valid range and does not clash with existing devices.
This method is ideal for networks without BootP or DHCP servers‚ or when a fixed IP address is required for the adapter. Remember to document the manually configured IP address for future reference and troubleshooting purposes.
After adjusting the thumbwheels‚ power cycle the adapter for the new settings to take effect.
BootP Configuration
BootP (Bootstrap Protocol) configuration allows the 1734-AENTR adapter to automatically obtain its IP address‚ subnet mask‚ and default gateway from a BootP server on the network. This simplifies network setup‚ especially in environments with numerous devices.
To utilize BootP‚ ensure a BootP server is active and properly configured with the adapter’s MAC address and corresponding IP address information. The adapter‚ with thumbwheels set to ‘999’ by default‚ will broadcast a BootP request upon startup.
If a BootP server responds‚ the adapter will receive its network settings and establish communication. Verify that the BootP server’s configuration matches the network infrastructure to avoid conflicts.
BootP is a legacy protocol‚ and DHCP is generally preferred for modern networks‚ but BootP remains a viable option for compatibility with older systems.
DHCP Configuration
DHCP (Dynamic Host Configuration Protocol) offers a streamlined method for the 1734-AENTR adapter to acquire network settings automatically. Similar to BootP‚ DHCP eliminates the need for manual IP address assignment‚ simplifying network administration and reducing potential errors.
To enable DHCP‚ ensure a DHCP server is operational on the network and configured to provide IP addresses within the appropriate range. The adapter‚ with thumbwheels initially set to ‘999’‚ will broadcast a DHCP Discover message upon power-up.
Upon receiving a DHCP Offer‚ the adapter will request an address‚ and if granted‚ will receive its IP address‚ subnet mask‚ default gateway‚ and DNS server information.
DHCP is the recommended method for IP address assignment in most modern industrial Ethernet networks due to its flexibility and centralized management capabilities.
