Built-in Firewall
This feature only applies to ControlEdge 900 controller and the
redundant ControlEdge 2020 controller.
Firewall is default to be enabled. The user can not turn off the Firewall
or can not reconfigure it. Only two uplink Ethernet ports are
supported by the Firewall function of the CPM.
Configuring IPsec
To support secure communications between the Experion (from
R500) and redundant ControlEdge 900 controller and redundant
ControlEdge 2020 controller, network layer security provided by
IPsec policies will be employed. To achieve this, both ControlEdge
900/2020 controller and the server node need a certificate issued by
a certification authority (CA) trusted by both.
For more information, see "Configuring a Secure Connection for
Experion Integration" in the ControlEdge PLC and ControlEdge RTU
Network and Security Guide.
To configure IPsec
1. Create the Certificate Authority.
2. Create a certificate for a Windows node.
a. Create a certificate.
b. Import certificate and private key on the target machine.
