Example: Coupling 2 drives (master, slave drive)

General The following example is based on the functionality of slave–to–slave
information communications via PROFIBUS–DP. It shows the steps which are ne-
cessary, using SimoCom U, to parameterize the master and slave
drive.
We recommend the following sequence when parameterizing:
1. Parameterizing the master, e.g. SIMATIC S7
2. Parameterizing the master drive
3. Parameterizing the slave drive

5.10 Slave–to–slave communications (from SW 4.1)
Standard telegram 108 for the master drive (publisher)
Standard telegram 109 for the slave drive (subscriber)
Default $5 m, sufficient for the traversing range
An SFC14/15 cannot be used
P1009 = 4 ms
Configuration, master drive matching telegram 108
––> number of process data
– 4 words, PKW
– 10 words, actual values to the DP master (inconsistent)
– 10 words, setpoints from the DP master (inconsistent)
