System Level Programming

With system level, it will be possible to control as well as monitor all the zones on system level. This makes it convenient by a system with a lot of zones.

When using system level programming, the group function block TECT_GROUP will still be applied as in group level programming. Also the TECT_HMI_MUX can be used. Thus the functionalities on group level are still available.

The ADR_SYSTEM_INFO points to the ZONE_INFO which contains the actual temperature and error word. They will be used directly in the HMI for alarm handling and trends because they should be delivered to HMI without interruption by TECT_HMI_MUX.
