PTQ-PDPMV1 ♦ Quantum Platform
PROFIBUS DP Master Network Interface Module for Quantum
Example #2


Stand-alone application scan time: 80 ms
Data (state RAM + unlocated variables): 300 Kb
Note: In addition to the above times for system overhead, the PTQ-PDPMV1 module may acquire
from 100 ms to 300 ms of switch-over time. All configured data is to be updated as fast as the
combined asynchronous events occur based on the processor scan time, backplane transfer time,
PTQ data handling time and PROFIBUS Master bus cycle time. PROFIBUS bus cycle time is
based on slave reaction time, sync time, baud rate and other bus delay times for a given number of
slaves on the network.
