User configurable input/output
One
specific input or output is assigned to a user-configurable input/output (configurable
I/O) during device commissioning.
The following inputs and outputs are available for assignment:
• Choice of current output: 4 to 20 mA (active), 0/4 to 20 mA (passive)
• Pulse/frequency/switch output
• Choice of current input: 4 to 20 mA (active), 0/4 to 20 mA (passive)
• Status input
The technical values correspond to those of the inputs and outputs described in this
section.
Signal on alarm Depending on the interface, failure information is displayed as follows:
