If Compact Mode with Sync is used (versus Compact Mode without Sync), one additional 16-bit
register to hold the Synchronization Output register. See Using the PROFIBUS-DP Compact
Mode for details on using this register and the differences between these two sub-modes.
The order of the output registers for an n-axis module with a Sensor DI/O running in Compact
Mode with Sync is shown below. O represents the RMC’s output base address. If your module
does not have a Sensor DI/O, drop the last two registers:
Register
Number
Contents
O + 0 Synchronization Input
O + 1 Command – axis 0
O + 2 Data out – axis 0
O + 3 Command – axis 1
O + 4 Data out – axis 1
: :
O + 2*n +
1
Command – axis n
O + 2*n +
2
Data out – axis n
O + 2*n +
3
Reserved by Sensor DI/O
O + 2*n +
4
Reserved by Sensor DI/O
The following chart shows the same for an RMC running in Compact Mode without Sync:
