Accessing PLC via WLAN from Handheld Device
Figure 30: Accessing a PLC from a handheld device using WLAN
This example describes how to use a Wireless Access Point to access the web
interface of a PLC on a wired network from a tablet or smartphone which uses
DHCP. The Wireless Access Point will function as a WLAN access point.
Please refer to the documentation for the handheld device and PLC on how to
configure their respective network settings.
Configuration
1.
Reset the Wireless Access Point to the factory default settings.
2.
In
Network Settings
, configure the IP settings as required.
- If the wired network uses DHCP, select
DHCP Relay Enabled
. The
DHCP server on the network will now be able to allocate an IP address to
the handheld device.
- If the wired network uses static IP, select
DHCP Server Enabled
and
set a Start Address for DHCP addressing. Make sure that the address
range does not contain any existing addresses on the network.
The Wireless Access Point will now function as a DHCP server and allocate an IP
address to the handheld device over WLAN.
Do not enable the internal DHCP Server if one already exist!
Do not enable the internal DHCP Server if there is already a DHCP server on the
network, as this may cause IP address conflicts!
