Endress+Hauser Deltapilot M FMB50 - Dynamic Behavior: PROFIBUS PA; Dynamic Behavior: FOUNDATION Fieldbus; Damping

Deltapilot M FMB50/51/52/53
14 Endress+Hauser
Dynamic behavior:
PROFIBUS PA
Reading cycle
• Cyclic: max. 30/s (dependent on the number and type of function blocks used in a closed-control loop)
• Acyclic: typical 25/s
Cycle time (update time)
min. 100 ms
The cycle time in a bus segment in cyclic data communication depends on the number of devices, on the
segment coupler used and on the internal PLC cycle time.
Response time
• Cyclic: approx. 8 to 13 ms (depends on Min. Slave Interval)
• Acyclic: approx. 23 to 35 ms (depends on Min. Slave Interval)
Dynamic behavior:
FOUNDATION Fieldbus
Reading cycle
• Cyclic: max. 10/s (dependent on the number and type of function blocks used in a closed-control loop)
• Acyclic: typical 5/s
Cycle time (update time)
Cyclic: min. 100 ms
Response time
• Cyclic: max. 20 ms (for standard bus parameter settings)
• Acyclic: typical 70 ms (for standard bus parameter settings)
Damping A damping affects all outputs (output signal, display).
• Via on-site display, handheld terminal or PC with operating program, continuous from 0...999 s
• Via DIP-switch on the electronic insert, switch position
"on" (= set value) and "off" (= damping switched off)
• Factory setting: 2 s
