Layer 2 fully supports a deployment on virtual infrastructure where it is available on the plant floor. The backend services run in virtual machines (VMs) supporting efficient resource management. The virtual infrastructure ensures all security, redundancy and backup requirements avoiding massive downtimes and disruption.

The client/server architecture allows an unlimited number of operator’s and engineer’s HMI clients to connect to Tenova Level 2 server tasks without any disruption.

Level 2 can communicate via OPC protocol (including the newer OPC UA standard) to PLCs on the Level 2 network.

Similarly, communication with Level 3 or other in-plant systems can take place using different methodologies based on customer requirements.
