Implementation Phase 3 Area Automation
Now that the plant floor Ethernet network is in place and you have several process cells automated/integrated into one production system, it is now time to add the SCADA system and Plant Floor Database. The SCADA system will provide for supervisory control of the entire production system as well as real-time data collection and process monitoring.

Implementation Phase 4 Integration with the Front Office
It is important to note that up to this point, we have been dealing strictly with the production automation system which we refer to as the Plant Floor Ethernet Network. This network has PLCs, HMIs, SCADA system and its own Database. The plant floor Ethernet network must be a highly stable and reliable industry grade network This network must remain secure from the outside world to insure data integrity and plant up time. The Plant Floor Ethernet Network is linked to the Front Office Network or other Business Information Systems through a series of routers and Fire Walls. This combination of network equipment helps to protect the Plant Floor Ethernet Network from accidental or malicious tampering.

Implementation Phase 5 Enterprise Level
Once the local plant is fully integrated, then it is possible to link the plants information systems with enterprise level information systems. This is done again by using a series of routers and a Fire Wall to insure security data integrity.
