Connectivity between objects

• Framework connectivityThe objects are linked automatically when specified in the specs file (xml/xls)

• User connectivityThe links are established by the user at the process control logic development time

Forced Mode and Position Status of I/O Objects

11/02/14 UNICOS 8

Forced Mode (“expert” privilege): For AI & DI Objects, when the operator forces

the value, the Position Status may become different from the Hardware Feedback.

For DO & AO Objects, when the operator forces the object, the Output Order sent to the process may be different from the Auto Position Request of the process.

Forced Mode may be useful for: Electrical tests Program simulation Degraded operation!
