ILX34-AENWG ♦ POINT I/O Platform Wireless Point I/O Adapter 3.2 Procedures Setup Guide Physical Setup 3.2.1 Adapter Components The Wireless Point I/O Adapter is a communications adapter for POINT I/O modules. The adapter provides an interface for controlling and communicating with POINT I/O modules from an Ethernet network. Page 16 of 79 ProSoft Technology, Inc.
Procedures Setup Guide ILX34-AENWG ♦ POINT I/O Platform Wireless Point I/O Adapter 3.2.2 Install the Wireless Point I/O Adapter on the DIN-rail Warning: You must follow all safety instructions when installing this or any other electronic devices. Failure to follow safety procedures could result in damage to hardware or data, or even serious injury or death to personnel.
ILX34-AENWG ♦ POINT I/O Platform Wireless Point I/O Adapter Procedures Setup Guide 3.2.3 Configure the Wireless Access Point Although the ILX34-AENWG can communicate with any 802.11b/g Access Point radio, ProSoft Technology recommends the RadioLinx series Industrial Broadband radios wherever performance and compatibility are required. The following configuration steps are for the RLXIB-IHW. Use the examples in these steps to configure your own Access Point to work with the ILX34-AENWG.
Procedures Setup Guide ILX34-AENWG ♦ POINT I/O Platform Wireless Point I/O Adapter IP Address: The IP address for all radios must be within the same subnet, and each radio requires its own unique IP address. You can assign static IP addresses, as in this example, or you can use DHCP (Dynamic Host Control Protocol) to manage and assign IP addresses automatically.
ILX34-AENWG ♦ POINT I/O Platform Wireless Point I/O Adapter Procedures Setup Guide 3.2.4 Configure the IP Address with the Thumbwheel Switches Before you can connect to the ILX34-AENWG for the first time, you must configure its IP address. The simplest way to set the IP address for your initial connection is to use the thumbwheel switches on the front of the adapter. The three thumbwheel switches represent the final octet for the private IP address 192.168.1.
Procedures Setup Guide ILX34-AENWG ♦ POINT I/O Platform Wireless Point I/O Adapter 3.2.5 Connect Power to the Adapter The ILX34-AENWG adapter requires an external source of DC voltage. The DC source voltage should be 24V nominal, with a range of 10V to 28.8V. Refer to the following illustrations for wiring information. Caution: Do not connect 120/240V ac power to this supply. Warning: If you connect or disconnect wiring while the field-side power is on, an electrical arc can occur.
ILX34-AENWG ♦ POINT I/O Platform Wireless Point I/O Adapter Procedures Setup Guide When you power up the POINT I/O for the first time, the adapter must assign addresses to every module in the backplane. POINT I/O modules are all initially configured at the same address. When you first apply power, all but one module on the backplane should show a solid red Module Status LED. One by one, the adapter resets these modules and assigns addresses.
