Webmaster: Networking 2 or more WebMasters using the optional Master capability key
Note: The Master capability is an option that must be purchased when ordering the WebMaster or may be added afterwards by ordering the "key" to activate the feature.
Setting up: |
 |
| If you're setting up a network with 2 or more controllers that are not on the customer's LAN, here's an easy way to program the Ethernet (LAN) settings. |
| Set the IP address of the Master to 10.0.100.29 (this is the factory default- you should not have to change it). The subnet mask should be 255.255.254.0. The gateway should be its own IP address (10.0.100.29). |
| For the Slaves, set the IP address as one above the address of the Master. For example, the first Slave should be 10.0.100.30 (one above than 10.0.100.29). Each subsequent Slave with be one above the previous Slave (in this example, the second slave would be .31, the third would be .32 and so on). All controllers, Master and Slaves will have the same subnet mask (255.255.254.0) and the same gateway as the Master. |
| In the Ethernet (LAN) settings, the default configuration of the WebMaster is independent. You must remember to program the Master WebMaster as Master, and each Slave as a Slave. The controllers will need to be restarted to save these settings. |
| If you're setting a Master-Slave network where the WebMasters are on the customer's LAN, then the IP address, subnet mask and gateway must all be compatible with the customer's network. This information comes from the LAN's IT administrator. Note that the gateway must be filled in for the sub network to function properly. If the IT administrator does not supply you with one, sometimes using the master's IP address will work. |
| In some installations, it can be difficult to obtain an IP address for WebMasters that are installed on a customer's LAN. Keep in mind that Webmasters now support DHCP, which means they can be automatically assigned an IP address by the network. To utilize this feature, enable DHCP on the communications page, set the Master/Slave configurations, cycle power to the WebMasters, and all the controllers should be on the LAN. Use the keypad or the USB connection to find out the IP addresses that have been assigned to the WebMasters. |
| Remember to change the Networking Settings on the Communications page for each WebMaster on the Network! The default is Independent. |
 |
| Above, Master is selected for the controller with the Master code. After you select the network mode, click “Submit”, and then restart the controllers. |
