SmartWire-DT will require a certain amount of time in order to transmit data
to the DS7-SWD soft starter. Likewise, the DS7-SWD soft starter will require
a certain amount of time in order to perform the corresponding commands.
Following are a couple of examples showing response times for cyclic data
transfers and for the feedback signal sent back to the PLC.
Example 1:
XC202... controller, PROFIBUS DP interface, 2 slaves
Size Set value
Baud Rate 500 kBaud at DP
250 kBaud at SWD
Start 150 - 200 ms
Stop 150 - 200 ms
Coast Stop 1.5 s (complete stop)
External Error 150 - 200 ms (complete stop)
Example 2:
XC202... controller, PROFIBUS DP interface, 58 slaves
Size Set value
Baud Rate 9.6 kBaud at DP
125 kBaud at SWD
Start 600 ms
Stop 600 ms
Quick Stop 2 - 2.5 s
In the case of PROFIBUS DP, the decisive factor for response time is the
baud rate, not the number of slaves.
