Example of a system configuration with analog I/O and digital I/O
System features:
●
The SITRANS SL is controlled by the automation system via analog I/O and digital I/O.
●
The measurement results of the SITRANS SL are output to the automation system via
analog output.
●
The digital outputs can be used to indicate warnings and alarms and the digital input can
be used to evaluate errors of external pressure or temperature sensors.
●
When external sensors are to be connected the first choice is to use analog input of the
automation system although direct connection via the analog input of SITRANS SL is also
possible.
●
A PC/PG used for the configuration of the automation system is connected to an
automation system via an MPI cable.
