Functions - Siemens SIPROCESS GA700 Operating Manual

The digital outputs can be used for different tasks, for example, signaling or control of valves.
The corresponding functions can be assigned to several digital outputs. These digital outputs
can perform the following tasks:
● Status message (function check, operating states)
● Output of maintenance-related messages, for example: maintenance demanded,
maintenance required, maintenance alarm
● Output of fault messages
● Output of the current measuring range and/or the current process tag
● Switchover of the process tag
● Output of limit violations
● Output of status of a result of logic operation
● Switching of solenoid valves
● Synchronization of AutoCal/AutoVal sequences of several devices ("Sync.", function
cannot currently be executed.)
● Signaling of different diagnostic states
You can find additional information on the functions that can be used under → Functions
(Page 153).
Information on the terminal assignment of the individual digital outputs in de-energized state
is available in the operating instructions of the device: → Table A-1 References 1 - Operating
Manuals LUI (Page 281).
Digital outputs on analyzer modules
In addition to the eight digital outputs of the basic device, each analyzer module also has
three digital outputs whose parameters cannot be assigned. These digital outputs are also
numbered through from "1" to "3" per analyzer module.
These digital outputs are responsible for transmitting the status information of the analyzer
module to specific applications. The assignment of the functions cannot be changed.
You can find additional information under → Table 6-25 Analyzer module: permanently
assigned digital outputs (Page 154).
