CX-Server OPC compatibility
Support for OPC data access v1.0 or v2.0
CX-Server OPC will work with any OPC compliant client supporting v1.0 or v2.0 of OPC
data access.
CX-Server OPC has been tested and is currently used with many leading SCADA packages
Support for Redundant PLCs
Any PLC supporting function blocks and Ethernet can have an identical partner configured

Support for Redundant Networks
CX-Server OPC supports Ethernet networks for redundant configurations.
Each network for the each device can be configured with a secondary network
Together with the device redundancy this can allow up to 4 levels of redundancy.
PLCs configured as a redundant pair will both write to the device network so the device
network must be able to handle this. ProfiNet is the recommended network for this.
