Reading cycle
• Acyclic: max. 3/s, typically 1/s (depending on command # and number of preambles)
• Cyclic (burst): max. 3/s, typically 2/s
The Deltabar FMD71/FMD72 offers BURST MODE functionality for cyclical value transmission via
the HART communication protocol.
Cycle time (update time)
Cyclic (burst): min. 300 ms
Response time
• Acyclic: min. 330 ms, typically 590 ms (depending on command # and number of preambles)
• Cyclic (burst): min. 160 ms, typically 350 ms (depending on command # and number of
preambles)
Damping
A damping affects all outputs (output signal, display):
• Via onsite display, handheld terminal or PC with operating program, continuous from 0 to 999 s
• Via DIP switch on the electronic insert, switch position "on" = set value and "off"
• Factory setting: 2 s
Damping can be switched on or off using a switch on the electronic insert. If the switch is on, the
time constant can be set via a parameter in the menu and if the switch is off, the output signal is not
damped (time constant = 0.0).
