BRX PLC Connection via WiFi Router SE-SL3011-WF
The WiFi Stride VPN router is a valuable options when:
•
Client mode - Wired internet access is not available to the equipment panel, or would be
impractical to install.
• Access point mode - VPN connections to multiple devices is desired without wiring
Ethernet cable to each.
• Client mode - Local operators want to limit access to a machine network by using their
smartphone as a WiFi hotspot. This allows the SiteLink WiFi router to connect as a client
and establish a VPN connection to the platform on an as-needed basis.
This example will step you through connecting to a BRX via the WiFi router, model
SE-SL3011-WF, in client mode. Internet access will be via the WiFi connection, and the BRX
PLC will be connected to a LAN port on the router. The router’s Ethernet WAN port will be
disabled.
NOTE: Regarding Ethernet access to a BRX PLC
If you intend to take advantage of any methods of remote access to the PLC, you need to consider the security
exposure in order to minimize the risks to your process and your PLC.
Security should always be carefully evaluated for each installation. Refer to the “Security Considerations for Control
Systems Networks” section of Appendix B.
Before You Begin
1. Know your BRX network settings
2. Know the SSID and password for the WiFi access point at your BRX location
3. Have your SE-SL3011-WF router, WiFi antenna and USB stick available
Setup
Remember that you can’t browse across the VPN to the router’s LAN network, so the BRX
PLC must be configured and the network settings known before you configure your router.
Configure the BRX PLC Network Settings
For our example, we’ll configure BRX PLC as follows:
• IP Address: 192.168.140.19
• Subnet mask: 255.255.255.0
• Default Gateway: 192.168.140.1 (the router’s LAN IP address) This must be on the same
subnet as the BRX PLC
