1. TCP/IP-communication in operation and control
Driving force to ease system integration
TCP/IP as a transport protocol utilised in new standards, like IEC61850
IEC60870 and DNP 3.0 will be adapted too

2. Integrating TCP/IP in field devices
An embedded protocol stack sharing the resources of the processor (new devices)
Extension via a connection box: TCP/IP upwards, e.g. Modbus downwards (retrofit)

3. Concerns about TCP/IP
Data security: monitoring, control and parametrization functions ?
Deterministic communication in packet switched network with different physical media
New solutions needed to ensure packet transmission up to application level (DSiP)
