Channel Selection:
The following 3 operating modes can be set:
Internal
Fieldbus
External
Mode Internal
In the mode internal, the AMI Silica works as a master.
2
nd
Sample Stream Option
The AMI Silica switches automatically between channel 1 and 2.
Sample Sequencer
The AMI Silica sequentially measures each single sample stream of
the Sample Sequencer.
Via an external PLC it can be defined which sample streams should
not be measured. In the example below, only the samples streams 2,
4 and 6 are measured, whereas the samples streams 1, 3 and 5 are
switched off. Sample streams which are switched off are marked with
an “x” behind the measuring value on the AMI Silica display.
Mode Fieldbus
The AMI Silica is controlled via fieldbus.
Mode External
In the mode external, the AMI Silica works as a slave.

Sample Stream Option
The 2
nd
Sample Stream option is switched between sample stream 1
and 2 via input, see Input
.
Sample Sequencer
The AMI Silica is controlled by the Sample Sequencer. The Sample
Sequencer in turn is controlled via an external PLC. Each sample
stream to be measured has to be activated by closing the respective
contact.
